  1. A photo of a person's eye taken at a medium distance is more than enough to trick a Samsung Galaxy S8 smartphone, according to researchers from the Chaos Computer Club (CCC). Samsung added the iris scanner authentication feature with the release of the Galaxy Note 7 model, launched last year, but the feature was hardly used as the company was forced to recall Galaxy Note 7 handsets due to faulty batteries that kept catching fire out of the blue. Arguably, it's with the company's latest line of flagship products where this feature will be really tested and used by most of its customers. Camera, printer, glue, and a contact lens Launched on March 29, the Galaxy S8 model is Samsung's most advanced product to date, featuring multiple biometrics authentication systems on top of the classic pattern and PIN locking systems. This includes a fingerprint scanner, a facial recognition system, and an iris scanner. According to research published today, it took a CCC researcher less than two months to breake the latter. Named Jan “Starbug” Krissler, this CCC researcher realized that by taking a photo of a phone owner's face, an attacker with physical access to the device would be able to unlock the phone just by printing the photo on paper and flashing it in front of the phone's front camera. But there's a trick to the attack. Modern iris scanners (and facial recognition systems) are programmed to use image depth in order to distinguish between (2D) photos and a human's real (3D) eye. Krissler bypassed this hurdle by gluing a contact lens on top of the image depicting the eye. This created a round surface on top of the iris photo, which was more than enough to trick the phone. Use a Samsung printer for best results (How ironic!) To get the best results, Krissler recommends that users take photos using a camera's night-shot mode, as it captures iris details better for individuals with darker eye colors. Ironically, Krissler also said he achieved the best results when he printed the iris photos using a Samsung laser printer. According to the researcher, "a good digital camera with 200mm-lens at a distance of up to five meters is sufficient to capture suitably good pictures to fool iris recognition systems." Samsung Pay wallet technology in danger The attack is worrisome on different levels. First off, Samsung announced the iris scanner feature would also be used to approve payments sent via Samsung Pay. The attack announced today not only endangers data stored on the phone but also funds stored in the user's Samsung Pay wallet. Second, many users that opt to use the iris scanners are inherently in danger because photos of someone's iris — or face for that matter — are incredibly easy to come by in today's age when everybody shares high-quality photos on a regular basis. For now, experts from the Chaos Computer Club recommend that users continue to use classic PIN-based authentication systems. Below is a video showing a step-by-step guide to how the iris scanner bypass works. Researcher has a history of hacking biometrics The researcher behind this attack has a long history of hacking biometrics systems. Krissler is the same person that two years ago had successfully bypassed the biometric security of Apple's Touch ID (fingerprint authentication) system. In the same year, the researcher also bypassed Panasonic's Authenticam BM-ET200 iris recognition technology, using nothing more than images he obtained off Google Image Search. In late 2014, Krissler achieved his biggest hack after he created a clone thumbprint of the German Defense Minister just by photographing her hand at a press conference. Earlier this year, Spanish phone expert MarcianoTech bypassed the Galaxy S8 facial recognition system two days after Samsung launched the phone. MarcianoTech bypassed the facial recognition scanner by using a photo of his face stored on another smartphone. If someone finds a way to bypass the Samsung Galaxy S8 fingerprint scanner in the following weeks, Samsung should just scrape its entire biometrics authentication systems and start from scratch for its next smartphone flagship series.

  2. Security researchers from Neseso are sounding the alarm on a vulnerability they've discovered in Samsung smart TVs that Samsung declined to fix. The security flaw affects Wi-Fi Direct, a Wi-Fi standard that enables devices to connect with each other without requiring a wireless access point. Smasung uses Wi-Fi Direct with its smart TVs to allow TV owners to connect to the TV via their phones, laptops, or tablets, directly, and not through the local access point. Samsung smart TVs use MAC addresses for authentication Neseso researchers claim that Samsung has failed in the implementation of this standard, as Samsung TVs only use MAC addresses to authenticate users. Other vendors use more solid authentication systems based on a Push-Button or PIN. Because anyone can sniff and spoof MAC addresses, this vulnerability opens the user's TV to getting hacked by anyone in the range of the TV's Wi-Fi Direct coverage. "Once connected, the attacker has access to all the services provided by the TV, such as remote control service or DNLA screen mirroring," Neseso researchers wrote in their report. Smart TVs could be used as entry points for other hacks Further, they argue that an attacker could use access to the TV as an entry point to a user or company's private network. The attacker can dump login credentials for the Wi-Fi network the TV is connected to and move laterally to other devices. The dangers are palpable for companies, as most have smart TVs in their offices, employee lounges, customer waiting rooms, or board rooms. Worse is that the Samsung smart TV Wi-Fi Direct feature is enabled by default every time the device boots up. Users are notified on screen when a whitelisted device connects to the TV via Wi-Fi Direct, but those warnings could be misinterpreted by TV owners, or missed altogether if nobody's watching the TV. Samsung said it's not a "security threat" Contacted by Neseso in mid-March, Samsung answered it doesn't view this feature as a security risk and declined to provide a firmware update, telling Neseso they don't view this issue as a "security threat." Researchers tested their attack on Samsung UN32J5500 Firmware version 1480, but say that other versions are most likely vulnerable as well. There is currently no workaround for protecting against attacks via Wi-Fi Direct except turning off the feature every time you boot/reboot your device. Earlier this month, at the Security Analyst Summit 2017, security expert Amihai Neiderman disclosed about the presence of 40 zero-day vulnerabilities in Tizen, the operating system that runs on Samsung smart TVs. The flaws were all unpatched at the time they were reported. Source
  3. Apple’s iPhone 8 is certainly one of the most exciting devices to come out of Cupertino facilities in a while, but it seems that the smartphone could face a two months release delay. Recent Korean reports confirm the previously rumored delay, but provide a different reason. According to a report from Nikkei Assian Review, one of the reasons why Apple’s iPhone 8 could be delayed is Samsung. Specifically, Samsung is facing some issues with production of OLED panels for Apple’s iPhone 8. Originally, Samsung planned to start production of OLED panels for the upcoming iPhone 8 in May, but the schedule will most likely be delayed to the end of June or even July. Apple is said to have ordered 70-90 million high-quality OLED panels from Samsung for its iPhone 8 smartphone. The delay could be caused by a number of reasons The OLED display isn’t the only reason behind iPhone 8’s delay, recent reports have revealed that Apple is facing issues with wireless charging modules, which cause the device to overheat. Moreover, the smaller printed circuit board is causing some problems for Apple, together with the 3DNAND flash supply. The report also reveals that memory chip suppliers are concerned “whether the upcoming iPhone's migration to advanced 3D NAND flash memory chips would be smooth enough to avoid tight supply or a shipment delay." Still, the supply chain source believes Apple and parts makers have enough time to make sure components are prepared for expected production and shipment schedules. The latest information does confirm the sayings of analysts, who predicted that the iPhone 8 will be announced in September, together with the iPhone 7s and iPhone 7s Plus. Hopefully, Apple will fix any issues that’s it has been encountering and won’t make customers wait until November to get their hands on the new phone. Aside from an OLED display and wireless charging technology, iPhone 8 is also expected to feature a larger battery and slimmer bezels. Source
  4. Plenty of people have been burned by Samsung, but that was mainly due to exploding Galaxy Note 7s. But now one guy has been burned hard on Twitter after trying to be funny and failing miserably. It all started when Samsung recently asked people to tweet the first pictures that they took with their Galaxy S8s. Many people politely did as requested, but there’s always one person who wants to ruin it for everybody else. In this case that person was @savEdward, who told Samsung that the first pic they took was in fact a picture of their genitalia. Unfazed by Edward’s attempt at humor however, Samsung shot back with a single hilarious emoji that spoke much louder than words ever could. See for yourself below. The moral of the story? Don’t mess with Samsung! Samsung recently asked people to send them the first pictures they took with their Galazy S8 It didn’t take long for the internet to show its appreciation Source
  5. Samsung logo Samsung subsidiaries in China must pay $11.6 million to Huawei Technologies for patent infringement, following a ruling made by a Chinese court. This is Huawei’s first victory against Samsung in legal disputes over intellectual property, according to Reuters. Last year, Huawei accused Samsung of patent infringement, claiming that the South Korean smartphone maker allegedly used 4G communications technology without a license. In addition, Huawei said Samsung infringed on user interface software and operating systems in smartphones. Samsung’s response to Huawei was its own patent infringement lawsuit, filed two months later. Samsung accused Huawei of allegedly infringing on six of its patents and sued the company through multiple courts in China. The court ruling regards more than 30 million smartphones and tablets One such court, the Quanzhou Intermediary Court, ruled in Huawei’s favor and ordered Samsung to pay $11.6 million in damages, as well as to stop infringing Huawei’s copyright immediately. Huawei’s claim affects over 30 million products, estimated to worth $12.7 billion, according to Reuters. The company sued for a total of 20 smartphone and tablet models that supposedly incorporated its technology, one of them being the Galaxy S7. Huawei stated that it welcomes the court’s ruling, while Samsung intends to decide on its response after reviewing the decision. Most likely, Samsung will look for ways to appeal the decision. Huawei currently holds over 50,000 technological patents, while Samsung has been involved in many patent disputes over the past few years. Last year, Samsung managed to overturn a decision made by the Supreme Court when it was ordered to pay $399 million in damages to Apple. The ruling was overturned and reopened by the Court of Appeal. Samsung had been ordered to pay the high sum for using rounded corners, bezels and an icon grid on its smartphones, very similar to what Apple employs on its iPhones. Source
  6. Even before its official launch, smartphone experts are criticizing Samsung Galaxy S8 phones after one of their colleagues managed to bypass the facial recognition feature that ships with these phones by flashing a photo of himself in front of the phone. In terms of bypass techniques, facial recognition systems getting fooled by photos is as bad as it gets, right there with storing passwords in cleartext. The flaw was spotted by Spanish phone expert MarcianoTech, who was testing the device at its official launch, at the Unpacked event that took place yesterday in New York, USA. The phones expert was actually live on Periscope when he first tricked the S8 with a photo of himself, shown via another device. The YouTube video above shows just the S8 facial recognition bypass. Samsung launched the S8 with many new security features, such as an iris scanner and a fingerprint sensor. MarcianoTech didn't attempt to fool the iris scanner with a photo of his eye but expect such tests in the following days. Experts believe the same flaw affects the S8+ model. As said before, tricking a face recognition feature with a photo is a big no-no, as this is the first thing developers of biometrics software makers test. If a facial recognition feature can accurately distinguish between individuals, the next test is usually the one for image depth, as not be fooled by 2D images. Source
  7. Intel had a tech day this week to discuss the future of its own 14nm and 10nm chips, and it laid out some impressive claims in the process. It also laid out what it believes is a better metric for calculating process nodes in the future, though we suspect TSMC, Samsung, and GloFo may all disagree. Intel’s presentation focused mainly on two related topics: The strength and characteristics of its 10nm node, and its proposal for a new (or rather, a return to an old) method of calculating process node scaling. Intel drives “hyperscaling” at the 10nm node Intel is claiming that its 10nm node will deliver a 2.7x improvement in transistor density compared with its 14nm products. That’s a significant jump over its 14nm products, and it’s not just the result of the improvements to various semiconductor manufacturing metrics. Intel has improved its 10nm scaling compared with 14nm through the use of two specific new technologies — single dummy gate, and contact-over-active-gate. Typically, logic cells use a pair of what are called “dummy gates” to isolate each cell from its neighbors. Intel has found a method of using just one dummy gate instead of using a pair of them, and has managed to recover significant space savings as a result. Each gate has multiple contacts that connect to the metal layers within a CPU. Typically, these contacts are offset from the gate. At 10nm, Intel is moving the contact to directly under the gate, which frees up additional transistor space. All of these advantages combined is why Intel is claiming such significant improvements compared with 14nm. The slides below includes visualizations of these improvements and how they collectively improve Intel’s 10nm process node. All slides can be clicked on to expand them in a new window. The general thrust of Intel’s argument is that these new technologies will give it a significant lead over its rivals and competitors in the foundry space. Intel vs. everyone at the 10nm node One major point of Intel’s presentation is actually something we’ve discussed before: When TSMC, Samsung, GlobalFoundries and Intel talk about 14nm, the process nodes they discuss are not identical. Each foundry has implemented different feature sizes and each of their nodes (16nm/12nm for TSMC, 14nm for Samsung and GF) has its own distinct characteristics. To some extent, the modern definition of a node has become “The bucket of technologies we periodically dump in to improve some aspects of transistor density, power consumption, and performance enough to justify moving to a new number.” The problem, at least for Intel, is that when a company like Samsung announces 10nm production, that’s actually roughly equivalent to Intel’s 14nm, which debuted in 2014. To get around this issue, Intel has described a method for calculating process node size that would weight certain factors differently than they are weighted today. Intel’s Process Architecture and Integration Director, Mark Bohr, described the formula in an editorial published by Intel: Measuring process node metrics in this fashion would give Intel an obvious advantage over all of its rivals. As such, it’s hard to imagine they’ll ever endorse it. Whether its TSMC with a new “12nm” node or potential future gaps between the various pure-play foundries at 7nm, nobody but Intel will substantially benefit from measuring process nodes differently, even if Intel’s method is more accurate. The slides below steps through some of Intel’s transistor density comparisons against its competitors’ nodes, as well as how it compares against them on specific metrics and how large it expects the gaps to be at 10nm. We can’t speak to the accuracy of Intel’s projections for its competitors at 10nm, but the company’s general projection matches what we’ve seen at the 14nm node. With Intel taking on more foundry customers (or trying to), it doubtlessly sees this as a potential barrier to those efforts. What’s the point of calling a node “10nm” (from Intel’s perspective) if that artificially inflates the value of what your competitors’ are selling and diminishes your own value? The other interesting question is how much these advantages will practically matter going forward. When Intel intended to break into the tablet and smartphone markets to compete directly against ARM, it had an obvious rationale for comparing its own performance against Samsung, GlobalFoundries, and TSMC. Today, Intel and the pure-play foundries once again move in different circles — but that could change in the future if Intel can land some significant foundry deals. The other reason foundry die shrinks aren’t as interesting as they used to be is for the simple reason that they don’t deliver much in the way of improved performance any more, at least not outside specific market segments. Six years ago, the Core i5-2537M was a Sandy Bridge-era core clocked at 1.4GHz base / 2.3GHz Turbo with a TDP of 17W. Today, Intel’s Core i5-7300U is a 15W chip with a 2.6GHz base clock and a 3.5GHz Turbo. It’s TDP is 15W. Intel, in other words, improved the base clock by 1.86x and the boost clock by 1.52x all while trimming the TDP. But in the desktop space, performance gains have been rarer, overclocking headroom has shrunk, and frequency gains have been doled out very sparingly. Intel has absolutely made progress over this time, but not at anything like a quick pace. Again, that’s not the company’s fault — it’s related, as we’ve said before, more to the difficulties with scaling silicon than anything — but with AMD surging back into the CPU fight, Intel may find itself under increased pressure to demonstrate that its 10nm hardware can do more than look impressively futuristic in a variety of graphs. Intel’s full presentations are available for download, if you’d care to flip through them yourself. Source
  8. Qualcomm Snapdragon platforms Qualcomm is undoubtedly the biggest chipset maker out there, its Snapdragon platforms equip many smartphones available on the market. By contrast, Samsung’s very own Exynos chip powers devices created by the South Korean company. Samsung’s Exynos chips don’t make it to smartphones developed by other companies on the market, although Samsung often creates Exynos chips that provide similar performance as Snapdragon platforms. The South Korean company equips its Galaxy S flagships with Exynos chips in certain countries, while the other variants run the latest Snapdragon platforms. Considering that Exynos chips can take on Qualcomm’s platform in terms of performance, it’s quite curious that they haven’t been featured in other phones, except for those made by Chinese manufacturer Meizu. The South Korean Fair Trade Commission has answered to this question. According to reports from the country, Qualcomm blocked Samsung from selling its Exynos chipsets to other smartphone makers, like LG, Huawei or Xiaomi. Samsung may be blocked from selling Exynos chips Apparently, Qualcomm abused the standard essential patent license and prevented Samsung from selling modems and integrated chipsets for about 25 years, said the Fair Trade Commission. Officials said in the resolution on the case of Qualcomm’s abuse of its market power that "Samsung Electronics has been blocked from selling its modem chipsets to other smartphone manufacturers due to a license deal it signed with Qualcomm." Back in December last year, the Fair Trade Commission decided to fine Qualcomm with $865 million over antitrust violations. The company violated the competition law and granted limited access to standard essential patents to competing chip makers. Qualcomm intends to appeal the decision, as the company stated that it “strongly disagrees with the KFTC’s announced decision, which Qualcomm believes is inconsistent with the facts and the law, reflects a flawed process and represents a violation of due process rights owed American companies under the Korea-U.S.” At the start of this year, Apple sued Qualcomm over excessive royalties and the Cupertino company is seeking $1 billion in damages. The lawsuit claims that Qualcomm charged Apple up to five times more in payments than any other patent licensors. Source
  9. Sony Xperia XZ Premium Smartphone makers don’t seem to run out of ideas when it comes to bringing new features and innovation to their products, in an attempt to make it easier for consumers to use them. Sony has just patented phone-to-phone wireless charging technology. The concept is quite interesting, Sony is thinking about a technology that would allow the smartphone’s battery to charge from another device, via NFC. The method would let users jump start a smartphone from another device, while also connect to both WiFi and power when entering a room. Sony’s method proposes adding a second wireless antenna for Near Field Communications (NFC) for transferring power rather than data. The phone could then be recharged from another smartphone, a refrigerator, washing machine or any other device that has a NFC power transmitter. Sony’s method comes with some limitations However, there’s a limitation that allows users to recharge a phone only if the device that is charging from is connected to a power outlet. Sony suggests that the option to charge a device wirelessly would show up on smartphones much like WiFi hotspots and users would be able to choose which to take charge from. The patent application was filed back in November last year, but was posted by the US Patent and Trademark Office only this month. It remains to be seen if Sony intends to start working on such a technology and include it in future flagships. Smartphone makers file multiple patents for new ideas, but not all of them reach development stages. Current wireless technology doesn’t support such a new method. The technology allows devices to charge over very short distances without cables, the main advantage being that users no longer need to plug and unplug phones in order to charge. They can simply place them on wireless charging ports and pick them up when they reach a full charge. The most popular standard for wireless charging is QI, supported by a number of companies, including Samsung, Google and Nokia. Source
  10. The Galaxy Book comes with support for a detachable keyboard Samsung joined the Windows 10 2-in-1 device party at MWC this year with the Galaxy Book, but information that was included in the official user manual reveals some features that could sound really odd at first glance. First and foremost, it’s worth noting that the Galaxy Book has been developed based on an approach that was pioneered by Microsoft with the Surface lineup, so it comes with touch support and a detachable keyboard that turns it from a tablet to a laptop in a second. What’s interesting is that the keyboard houses some important parts as well, including the NFC module, so Samsung has developed the Galaxy Book in such a way that when it’s removed and the device enters tablet mode, performance is automatically reduced. Beware the overheating Samsung explains in the manual (via MSPU) that “if you use the device without connecting the Keyboard Cover, the device’s speed and performance may be affected. Use the device with the Keyboard Cover connected.” Even though the company doesn’t explain why exactly this is happening, the Galaxy Book most likely cuts the power in order to save battery life, so you can use the device for a little longer even though the keyboard is no longer connected. Additionally, Samsung also provides guidance to make sure that the Note 7 catching fire nightmare doesn’t repeat, explaining that buyers who notice the Galaxy Book getting super-hot on a regular basis should contact the company for assistance. “When you use apps that require more power or use apps on your device for an extended period of time, your device may feel hot to the touch. This is normal and should not affect your device’s lifespan or performance. If the device overheats or feels hot for a prolonged period, do not use it for a while. If the device continues to overheat, contact a Samsung Service Centre,” the firm says. The Galaxy Book is available in two different sizes and in addition to the detachable keyboard, it also supports pen input, just like Microsoft’s Surface line. Source
  11. Smartphone OS sales share The latest Kantar World Panel report reveals market trends in the past period, providing an insight into smartphone OS sales. The study shows that iOS continued to grow in most regions, except for Japan, Spain and Urban China. On the other hand, Android grew in the US, and accounted for 74.3% of smartphone sales, an increase from 72.9% in the three months ending January 2016. iOS recorded a share of 22.7%, while iPhone 7 remained the top-selling smartphone in major European countries. Newly announced Nokia 3, 5 and 6 smartphones are said to leave a mark in European markets, especially since Nokia accounted for 6% of phone sales in EU5 at the start of 2016. It was the fourth largest brand in Great Britain, Germany, France, Italy and Spain. Android dominates the market in Asia with 83.2% of smartphone sold, after increasing 9.3% during the three months period ending January 2017, while Huawei continued to account for over a quarter of smartphone sales at 26.6% for the three months ending January 2017. Apple is the second largest smartphone seller in Asia with 16.6%, but continues to experience year-on-year decline resulted from increased competition from local manufacturers. 70% of the US market is dominated by Apple and Samsung The numbers are quite different in the US, where Android accounts for 56.4% of smartphone sales, down 1.8% from a year earlier. iOS’ share is 42% of sales, up 2.9% year-on-year, while 70% of the US domestic market is dominated by Apple and Samsung, with LG being the third largest manufacturer and accounting for 11.1% of sales. The report mentions that Android and iOS will soon be the only two smartphone ecosystems moving forward, while phone manufacturers will have to adapt in order to remain competitive on the market. In addition, no other mobile OS has the capacity to challenge Android and iOS, and the situation won’t change in the near future. Source

  13. Android 7.1.1 Nougat Running Surprisingly Well on a 7-Year Old Galaxy S1 Samsung released the Galaxy S in June 2010 YouTuber XTvideos posted a video showing how Android 7.1.1 Nougat performs on the 7-year old Galaxy S smartphone, announced in March 2010 and released a couple of months later in June. The video shows the first boot of Galaxy S1 i9000 running the latest version of Android. Obviously, this is an unofficial CM version of Nougat, nobody expects Samsung to release an update for devices so old. The smartphone runs a bit slow, it takes some time to load the settings menu, and the phone is running a clean OS, no apps were flashed. The user installed CyanogenMod 14.1 on the Galaxy S (GT-I9000), and since it’s an unofficial version, the phone is a bit slow in certain areas. The phone also appears to have the December security patch, which was the latest when the video was uploaded. 512MB of RAM and Hummingbird chipset inside The video shows that 7.1.1 Nougat contains most of the features that you would expect, like a revamped notification area and even quick reply. The phone can open all settings menus and it provides the user with access to developer options, without crashing, freezing or shutting down. Samsung’s Galaxy S1 (GT-I9000) had a 4-inch AMOLED display with 480 x 800 pixel resolution and Corning Gorilla Glass coating on top. It ran Android 2.1 Eclair out of the box and later received an update to 2.3 Gingerbread. These two versions haven’t been included in Android Distribution reports for quite some time now, meaning that they’re market share is well below 0.1%. Moving on the Galaxy S1 came with 512MB of RAM, 8 or 16GB of internal storage which could be expanded to 32GB with a microSD card and ran a Hummingbird chipset or Exynos 3110 with a 1.0GHz Cortex-A8 processor, coupled with PowerVR SGX540 graphics processing units. Rear camera capacity reached 5MP with autofocus, while the secondary camera was VGA. The phone drew power from a removable 1,500mAh battery. Source
  14. Xiaomi Can Silently Install Any App On Your Android Phone Using A Backdoor Do you own an Android Smartphone from Xiaomi, HTC, Samsung, or OnePlus? If yes, then you must be aware that almost all smartphone manufacturers provide custom ROMs like CyanogenMod, Paranoid Android, MIUI and others with some pre-loaded themes and applications to increase the device's performance. But do you have any idea about the pre-installed apps and services your manufacturer has installed on your device?, What are their purposes? And, Do they pose any threat to your security or privacy? With the same curiosity to find answers to these questions, a Computer Science student and security enthusiast from Netherlands who own a Xiaomi Mi4 smartphone started an investigation to know the purpose of a mysterious pre-installed app, dubbed AnalyticsCore.apk, that runs 24x7 in the background and reappeared even if you delete it. Xiaomi is one of the world's largest smartphone manufacturers, which has previously been criticized for spreading malware, shipping handsets with pre-loaded spyware/adware and forked version of Android OS, and secretly stealing users' data from the device without their permission. Xiaomi Can Silently Install Any App On your Device After asking about the purpose of AnalyticsCore app on company’s support forum and getting no response, Thijs Broenink reverse engineered the code and found that the app checks for a new update from the company's official server every 24 hours. While making these requests, the app sends device identification information with it, including phone's IMEI, Model, MAC address, Nonce, Package name as well as signature. If there is an updated app available on the server with the filename "Analytics.apk," it will automatically get downloaded and installed in the background without user interaction. Now the question is, Does your phone verify the correctness of the APK, and does it make sure that it is actually an Analytics app? Broenink found that there is no validation at all to check which APK is getting installed to user's phone, which means there is a way for hackers to exploit this loophole. This also means Xiaomi can remotely and silently install any application on your device just by renaming it to "Analytics.apk" and hosting it on the server. Hackers Can Also Exploit This Backdoor Since the researcher didn't find the actual purpose of the AnalyticsCore app, neither on Googling nor on the company's website, it is hard to say why Xiaomi has kept this mysterious "backdoor" on its millions of devices. As I previously said: There is no such backdoor that only its creator can access. So, what if hackers or any intelligence agency figure out how to exploit this backdoor to silently push malware onto millions of Xiaomi devices within just 24 hours? Ironically, the device connects and receive updates over HTTP connection, exposing the whole process to Man-in-the-Middle attacks. Even on the Xiaomi discussion forum, multiple users have shown their concerns about the existence of this mysterious APK and its purpose. How to Block Secret Installation? As a temporary workaround, Xiaomi users can block all connections to Xiaomi related domains using a firewall app. No one from Xiaomi team has yet commented on its forum about the question raised by Broenink. We'll update the story as soon as we heard from the company. Meanwhile, if you are a Xiaomi user and has experienced anything fishy on your device, hit the comments below and let us know. Source
  15. Explosive Start for Samsung Galaxy Note 7: More Phones Catch Fire While Charging Buy a Note 7, and get a free fireworks show in your bedroom If you’re an iPhone user, and you know what we’re talking about already, try not to smile too much because this is getting serious, and it involves severe damage that could actually lead to people getting injured. You'd better put firemen on speed dial A report that has recently reached the web reveals that a Samsung Galaxy Note 7 caught fire while charging, even though the owner was using the USB Type-C charger that Samsung itself included in the box. From the photos posted by the owner, it’s very clear that the phone exploded on the left side, but why it happened is yet to be disclosed. Obviously, Samsung has all the reasons in the world to be worried, so they have already contacted the owner to offer compensation and investigate. And now it seems that Samsung has even more reasons to be worried because it turns out that a similar explosion impacted not one, not two, but several Galaxy Note 7s. Photos and reports that have reached the web in the last few hours seem to point to similar cases, but it’s worth mentioning that we can’t tell exactly how many they are at the moment. Also, it’s hard to say whether some of the photos that have been posted lately and that allegedly refer to different cases are actually showing the first Note 7 that caught fire. A report coming from BusinessKorea reportedly has a new case of an explosive Note 7, and it includes information that confirms Samsung is aware of the problem and is now investigating. “There was another explosion of the Galaxy Note 7. It was my friend’s phone. A Samsung employee checked the site and he is currently in talks over the compensation with Samsung. You should use its original charger just in case and leave the phone far away from where you are while charging,” the aforementioned source writes citing someone who also got to see fireworks in their bedroom thanks to the explosive Note 7. Happening with original Samsung charger In most of the cases, owners who claim that their Note 7s caught fire say they used the genuine charger that Samsung offered in the box, so if this is true, the Koreans might really have a big problem here. There are people out there who have already decided to hold onto their purchases just because they’re afraid the Note 7 can explode for them too. And as compelling as Samsung’s buy-a-Note-7-get-a-free-fireworks-show offer might seem to be, the Korean firm is on thin ice right now. And it’s not all because of the damages that its explosive device could cause, but also because Apple is getting ready to take the wraps off the iPhone 7 in exactly one week. The Note 7 is a direct competitor to the iPhone 7, and it’s pretty clear that these reports are hurting its sales. For more evidence of exploding Notes, you can check out the gallery below, as well as the video after the jump - they claim to be from separate cases, but as mentioned, this cannot be confirmed right now. And, Timothy, you'd better stop smiling, you do know that this happened with some iPhones too, don’t you? Source
  16. Just recently, Samsung’s massive 15.6TB SSD began selling at retailers for $10,000. The 15TB drive was impressive at the time, but now it looks like Seagate is stealing the limelight with the announcement of its 60TB SSD. Seagate showed off its massive SSD at the Flash Memory Summit this week, though it was only there for demonstration purposes, so it isn’t really a full-blown product just yet and likely still needs some work. As PCworld points out, if Seagate can deliver on this, then its SSD would be four times larger than the current largest SSD in the world, Samsung’s PM1633a, the $10,000 15TB drive. Much like Samsung’s offering, the Seagate 60TB SSD is a SAS drive in a 3.5-inch form factor. It isn’t really for consumer use but would work well for server use, where you can double down on mass storage and save on rack space. The exciting part is that this drive is based on a “flexible architecture” and could end up scaling to support 100TB of storage in the same form factor, according to the official announcement.

  17. New GDDR6 Memory Could Hit GPUs In 2018 Samsung believes the days of good, old GDDR5 are numbered as VR and games demand better graphics Virtual reality and gaming are changing the way PCs are built and driving the development of new types of memory for GPUs. A successor to the GDDR5 memory used in most GPUs -- called GDDR6 -- will be on its way by 2018, according to a presentation by Samsung executive Jin Kim at the Hot Chips conference this week. GDDR6 will be a faster and more power-efficient form of graphics memory. GDDR6 will provide throughput of around 14Gbps (bits per second), an improvement of 10Gbps with GDDR5. Although Samsung has targeted 2018 for GDDR6, new graphics memory usually takes a long time to reach the market, so the estimate may be aggressive. GPUs will need to be designed for the new memory, and components will need to be validated and tested, all of which takes time. Applications like VR and gaming are putting a heavy load on GPUs, under stress to deliver the best graphics. VR headsets like Oculus Rift and HTC's Vive only work with premium GPUs. GDDR6 will help GPUs deliver faster performance while drawing less power. The need for more GPU performance is already changing GPUs. New types of memory like HBM (High-Bandwidth Memory) and GDDR5X, which offer faster bandwidth, are already being used in new GPUs from AMD and Nvidia. GPUs with HBM and other new memory are still priced at a premium. But GDDR6 -- like GDDR5 -- could be used in low-priced GPUs. It'll also be easier for GPUs to transition from GDDR5 to GDDR6 or GDDR5X than to HBM, which redefines the memory subsystem. It's clear that Samsung is putting its weight behind GDDR6, while rival Micron is backing GDDR5X. Nvidia's GeForce GTX1080 GPU has GDDR5X memory. Samsung also backs HBM. GPUs are also getting faster throughput, driving a need for faster memory. Faster memory helps GPUs process graphics faster, and the graphics can then be sent to memory, CPU, and storage via quicker interconnects like Nvidia's NVLink or the upcoming PCI-Express 4.0. Advances in manufacturing have also created the need for new GPU memory. Some of the latest GPUs based on Nvidia's Pascal and AMD's Polaris architectures are manufactured with new techniques including FinFET, a 3D structure in which chips are stacked. New memory like HBM and GDDR6 are designed for such new chip structures, while GDDR5 memory has been designed for older GPUs made using older manufacturing technologies that don't use stacked chips.

  18. Will also facilitate graphics cards with 64GB of VRAM. So far we have only seen limited hardware releases packing HBM1 or HBM2 memory but sk Hynix and Samsung are already working on HBM3 and other memory technologies and teased this fact at the current Hot Chips Symposium in Cupertino. According to slides published at Hot Chips, the next generation HBM will offer improved density, bandwidth, cost, power efficiency, and more. AMD used HBM1 in its Fury range of graphics cards. Nvidia used HBM2 in its Pascal-based Tesla P100 accelerator. For HBM3, perhaps AMD will be the first company to make a shipping product using the new memory, as its roadmap says the Vega architecture GPU (with HBM2) will be followed up with the Navi GPU with 'NextGen Memory'. In a more specific information release, at the recent IDF, Samsung published a slide showing HBM3 will offer more than twice the density and bandwidth of HBM2. It directly compares HMB2 and HBM3. Check out the table below to easily see the advances. In other Hot Chips memory news, sk Hynix said it was looking forward to expanding HBM tech to HPCs & Servers, Networking & Graphics Card products, and Client Desktops and Laptops. For these purposes HBM2 memory will be available in sizes up to 32GB (4 stacks of 8 Hi modules). Cheaper chips – GDDR6 and 'Low Cost HBM' At the more affordable end of the new memory technology market Samsung detailed a couple of interesting new developments. At Hot Chips it showed off slides illustrating progress with developing GDDR6 and with a new type of HBM dubbed 'Low Cost HBM'. GDDR6 is expected to arrive as the successor to GDDR5X in 2018. Currently GDDR5X can achieve 10Gbps with that bar being raised to 12Gbps shortly. As you can see from the Samsung slide, above, GDDR6 will offer a bandwidth of about 15Gbps from the start and greater power efficiency. Samsung's plans for Low Cost HBM are interesting. It will remove the buffer die, and reduce the number of TSV (through-silicon via) connections, interposers and more, for cost competitiveness. However, on a positive note, it will offer 50 per cent improved pin speeds. As you can see from the slide, above, while HBM2 offers around 256GB/s bandwidth the Low Cost HBM will not be that far behind with approx 200GB/s. Low Cost HBM will be an undisclosed fraction of the price of HBM2 and, importantly, it targets the mass market. View: Original Article
  19. Don't get too excited - it costs a bomb Samsung is shipping its PM1633a SSD which has 15.36TB of storage space however you are not going to get much change out of $10,000. Samsung now has the drive available at select retailers but at $10,000 it is one of the most expensive SSD storage drives around. Pricing seems to vary too with CDW asking $10,311.99 while SHI wants $9,690 on pre-order. There is a 7.68TB flavour but that is $5,700. The SSDs are based around 16 of Samsung's 256Gb TLC 3D V-NAND memory chips. These chips make a 512GB package which are then scaled up. The biggest drive uses 32 of those packages to build the largest of the PM1633a SSDs. The is a new controller specifically for this drive to increase the performance offered. The 15.36TB SSD offers sequential read performance of up to 1200 MB/s and sequential write performance of up to 900 MB/s using a SAS-12Gbps interface. Random read operations are 195,000 and write speds are 31,000 IPOPs. Those wanting to spend less money and needing less storage can get 480GB, 960GB, 1.92TB, 3.84TB, and 7.68TB models. Although it looks pricey, actually it works out being cheaper for business running massive data centers. Power consumption is around 11W active and 4.5W idle for the SSDs. View: Original Article
  20. That’s 10x cheaper than 3D NAND from the likes of Samsung, SanDisk, SK hynix and others. If you haven’t heard of BeSang Inc, it is the company that invented and licenses 3D monolithic chip technology to SK hynix. According to a report published by the EE Times, BeSang has become frustrated with SK hynix’s “slow implementation of its monolithic 3D technology,” and has thus started to open its doors to rival memory makers, and will now even contract-fab its latest architecture NAND memory chips for others. 2¢ per gigabyte Now here’s the eye catching part of this story: BeSang has announced (PDF) its 3D Super-NAND flash memory, which offers the lowest cost per bit in the NAND market by quite some margin. As you can see from the graphic reproduced below, BeSang claims this NAND provides a 10x cost advantage, with 10x less capital investment, and 10x more wafer throughput. Put into cost terms BeSang can facilitate 3D NAND production at about 2¢ per gigabyte, rather than the current industry norm of 20¢. Dr. Yohwan Koh, former SVP and head of NAND business at SK hynix, and currently advisor at BeSang Inc, explained how BeSang streamlines the 3D NAND manufacturing process: “Other 3D NAND has sequential manufacturing process to build stacked memory layers, staircase bit line contacts, and periphery logic. It takes usually more than 10 weeks to complete manufacturing process. However, 3D super‐NAND takes only 5 days to complete advanced 3D non‐volatile memory cells thanks to parallel manufacturing”. Samsung 48-layer 3D NAND (left), BeSang 3D Super-NAND (right). In the space that traditional 3-D NAND fits a single cell, BeSang claim to be able to fit up to 50 cells, thus its beats by 3X a 48-layer Sansung single cell with 150 cells for a five-layer BeSang 3-D NAND. Further explanatory quotes via EETimes reveal that BeSang’s new monolithic 3D Super-NAND fits 30 bits in the same area as one bit in competitor processes. BeSang’s design is simpler and more efficient, especially the way it implements staircase word-line architecture. BeSang’s new 3D Super-NAND isn’t some pie in the sky research project. It is licensing its technology now and also offering turnkey delivery of 3D Super-NAND. Commercial customers can order 15nm or 20nm 3D Super-NAND chips with a minimum order value of $30 million. Furthermore, BeSang promises single-chip 1-terabyte 3D Super-NAND modules will be developed within two years from now. SanDisk's 48-layer 3-D NAND costs more per bit than 2-D NAND according to ForewardInsights. The cell size of 3D NAND is about 10X bigger (31,000 square nanometers) than planar 2-D NAND due to the use of over 60 percent of its area for control logic (34 percent), a tungsten isolation slit (20 percent) and a word-line staircase (26 percent). BeSang claims its tiny normal-sized vias can pack millions of interconnects per 3-D chip layer resulting in a lower cost-per-bit than Samsung's 32-, 48- or 64-layer 3-D NAND. BeSang 3-D chips locate their interconnection, selection and read-write logic on the bottom and its vertically stacked NAND cells tightly packed on the top.

  21. Samsung to Shift from Android to Tizen OS on All Mobile Devices, Exec Says The statement was made by a Samsung Executive A Samsung executive stated that Samsung is considering the expansion of its Tizen software to all company devices, in detriment of Google’s Android platform, according to Korea Times. The company is reportedly trying to reduce its dependency on Google’s mobile OS. The global platform market is currently dominated by Google’s open-based platform and the company even supports third-party developers in the search of expanding its base. The executive also added that Samsung has fallen behind when it comes to developing content and its own platform, but the company "is getting much better". He added that Tizen allows developers to make all sort of corrections and redistribute updates to others. Samsung’s Tizen is packed with applications from the largest developers and even some apps that replace the current options available in Android. Samsung developed the Samsung Pay app for making payments, to compete against Android Pay. Smartwatches, some household appliances and Z-branded Samsung phones run on Tizen Samsung implemented Android OS on most of its devices, but did feature Tizen OS on Z-branded phones in India, smartwatches and some household appliances. This is one of the reasons why Samsung is currently testing the Tizen OS in India, where it sold 64 million phones in the first quarter of this year. The company even invited companies in Russia to promote the Tizen software and it plans to launch campaigns and hold forums for developers to expand Tizen’s base. IDC market research firm predicts that Tizen’s share in the wearable devices market will increase by 11.3% until the year’s end, while Apple Watch OS and Android Wear will have 49.4% and 21.4% market share.

  22. Malicious DLL can lead to pwnage Another vulnerability has emerged in Samsung's Software Updater (SW Update) service – this time giving an attacker potential “full control” over a system. Announced by German consultants Blue Frost Security, the vulnerability could be exploited to give an attacker full control over a victim's machine. To exploit the vulnerability, posted to Full Disclosure, the attacker needs authenticated access to the target machine, so they can drop a crafted DLL into the SW Update directory. That's because SW Service allows any authenticated user to write to the C:\ProgramData\Samsung\SW Update Service\ directory. On the next restart, the advisory states, the crafted DLL will run and the attacker will have full control of the target. Sysadmins should update to SW Update version 2.2.7.24, or if they can't, they should change the permissions on affected machines so users can't write to the SW Update directory. Back in March, the same service was found to be vulnerable to a man-in-the-middle attack. PC vendors' OEM software has been under the spotlight since May, when Lenovo, Acer, Asus, Dell and HP were spanked over what Duo Security called “vendor-incentivized crapware”. Article source
  23. Howdee, Maybe someone can help me with the following problem. I just bought an external 2.5 inch hard drive (Seagate Backup Plus 4tb) with the intension of playing videos on my Samsung tv (USB 3.0) but the hard drive does not appear on the screen. It seems my tv does not recognize the hard drive.The format is NTFS but i can change that to exFAT wich i already tried but no difference. It's nice to have so much backup space but the intension was to watch videos on my tv. I know there are some real technicians amongst you all. So could anyone please help me to solve this (if possible)? Thanks in advance and have a nice day! ronkanon.
