  3. Hello Gents, Press K (kick up my butt), if you reckon, I'm too unaware.. but I have my excuses- busy with work etc, so: (fed up having so many apps, conflicting contact issues etc), wonder, if somebody would have new (better) suggestions? Skype had it's glory days, but is too big, too unsafe, too much data FB Messenger is sort of "must", due to social interactions Like Telegram, but ever so few other users, also, it is not 100% as secure no more, What'sApp is OK, as there are some old contacts, sometimes handy, bhuuuttt Duo google product, expect to be failures, as per usual Hangouts- OK, just not sure if worth keeping it, as other apps-client do the same Thanks!

  8. Telegram Desktop is a powerful, cross-platform messenger app that enables you to get in touch with other users without worrying about data interception and stealing. Focusing on security, it encrypts all conversations and shared files and stores them in the cloud, allowing fast synchronizations and quick access to the message database from anywhere in the world. A more secure alternative to other messaging apps Deploying versions for all major mobile platforms like Android, iOS (known as Telegram Messenger) and Windows Phone, but also desktop operating systems (Windows, Mac OSX and Linux), Telegram Desktop becomes a good alternative to other more popular messaging programs, such as WhatsApp, currently available exclusively on mobile platforms. As mentioned above, the plus it brings is improved security, putting privacy above everything else. Messages you send via Telegram Desktop are automatically encrypted before they are stored online. Send broadcasts and share files Telegram Desktop features an intuitive interface that encases a list of your contacts and displays the conversation with each. In order to create your account, you will be prompted to enter your name and provide a valid mobile phone number, which is used for generating a security code. Users can create groups comprising up to 200 contacts and broadcast messages to a maximum of 100 people that are using Telegram, regardless of the platform of their choice. The application features desktop notifications for incoming messages and supports file and photo sending, ensuring compatibility with any format, be it documents, archives, music files or pictures. And like in any messaging application out there, conversations can be enriched using various funny emoticons. A secure and user-friendly messaging app Relying on the advanced security protocols, Telegram Desktop delivers a messaging application that is worth trying, at least. Not only that your messages are protected at all times, but you can easily access them from any mobile or desktop device, no matter where you are. v 1.1.2 stable Emoji icon tooltip about hiding the sidebar.

  9. Opera 45 With Reborn Goes Beta Today, project “Reborn”, Opera’s redesign process reaches the beta stage. It’s full of user interface improvements, but it also brings you quite a few new features. Read on and enjoy one of the longest list of changes in the Opera’s beta channel history! What is Reborn? It’s more than just a UI refresh. Reborn is a codename for the project that is gradually redesigning the entirety of Opera’s user experience. Bringing along a fresh look, it has a set of new, handy features, new icons, colors, wallpapers, and a touch of animation. Reborn is inspired by Opera Neon and shares its vision of making Opera’s UI truly modern, simplified, refined, and playful. Brand new look and feel Opera’s entire layout has been updated with a new, high-quality graphical design that is more consistent across platforms. The tabs are simplified, lighter, and more elegant, making it easier to locate open tabs. The new sidebar is more subtle and refined with a touch of animation. The Speed Dial has also been renovated with smooth animations. Browser sidebar Opera’s sidebar has been moved from the Speed Dial to the main browser window, similar to how it is in Opera Neon. It provides one-click access to important tools such as bookmarks, history, personal news, and extensions. You can customize the tools that appear in the sidebar according to what you find useful. The new sidebar will be visible by default for new users installing Opera beta for the first time. Current users of beta will find the option to turn it on by flipping the pin/unpin switch at the bottom left of the Speed Dial. Chat with your friends while browsing Chatting with your friends while browsing the web doesn’t always work seamlessly. Switching between tabs when responding to a message is cumbersome and inefficient. Reborn allows you to keep your favorite messenger as a side tab for an easy reach. Three popular communicators are now available directly in the sidebar: Facebook Messenger, WhatsApp, and Telegram. To use any of them, simply click their icon. After you log in to the site, there are two ways of using this feature: you can open it in overlay or pin it side-by-side with your current tab. Pinning a communicator allows you to combine online chatting with a full browsing experience. If you use more than one messenger, you can easily switch between them by using our shortcut key for quicker access (⌘ + ⇧ + m on macOS, CTRL + SHIFT + m on Windows and Linux). The three-dotted menu button allows you to log out from your sidebar communicator without needing to visit the communicator’s website. From the menu, you can also mute your communicator’s notifications. Give your browser a new coat of colors Opera is now available in two color themes: light and dark. You can also select one of the cool backgrounds that perfectly complement Opera’s new look and feel. For this beta release, we have prepared some completely new ones. Let us know which one you like the most. Both the background wallpaper and the browser’s color theme can be managed in the “customize start page” panel and in browser settings. Fresh and refined icons Opera’s “rebirth” also means a complete icon overhaul. New icons are even more refined and elegant, and some even change colors when active. We have carefully optimized the icons for various DPIs in order to make them look perfect. Animations Animations make the Reborn interface more alive and playful. The most visible one can be found when opening private mode. Windows 7 look and feel One of Reborn’s goals is to bring a more consistent look across all platforms. This doesn’t mean Reborn will disregard the browsing experience users have been familiar with on different platforms, such as Windows 7. Despite all the changes, Reborn has retained Windows 7’s well-known platform feeling with transparent borders and a system button to close, maximize, and minimize a window. Narrow sidebar for macOS The sidebar in the Mac version can be now as narrow as on Windows. To adjust it, go to Settings -> Browser -> Sidebar -> “Enable Narrow Sidebar,” or use the sidebar context menu. New bookmark pop-up Opera now brings you a new pop-up when adding bookmarks which includes the “Finished” button. This option gives a clearer way of adding bookmarks for users who missed the confirmation that a new website was already added to the bookmark folder. Ad blocker improvements Opera automatically reloads a page when toggling ad blocking on or off for that page. It’s especially useful if you want to quickly flip the switch and it gives you much more control and comfort while browsing with ad blocker. Also, we have added some important changes to the block list management. Now, you have control over which block lists are loaded. Easylist and EasyPrivacy are turned on by default. Other lists, including regional and custom lists, can now be managed through the “Manage Lists…” dialog. Let us know if there are any other lists that you would find beneficial. Also, Opera now offers support for more advanced CSS selectors, which helps you block more ads. Spring cleanup for languages As part of a spring cleanup we have removed support for the least-used languages in the browser user interface. While we would like to support as many languages as possible, this decision frees up our time for other important tasks. The discontinued languages are Azerbaijani, Macedonian, New Norwegian, Uzbek, Afrikaans, Croatian, Kazakh, Zulu, Frisian, Punjabi, Gaelic, Irish, Myanmar, Sinhala, and Urdu. After this, Opera supports 48 different languages. Performance and security changes H.264 video works in Windows 8.x again and it now has the same hardware support as Windows 7 and Windows 10, both given in the last developer release. Opera adds in-form warnings for sensitive fields when the top-level page is not HTTPS. Whenever you start filling in your password or credit card number on a page, which is not HTTPS, the warning will appear. If you’ve made it this far, go on and check out the changelog with all the backports listed.

  10. Telegram Is Rolling Out Voice Calls: Secure, Crystal-Clear, Constantly Improved By Machine Learning(AI-Powered) Voice Calls: Secure, Crystal-Clear, AI-Powered Over the past few months, we’ve worked hard to make sure Telegram calls are the best in terms of quality, speed, and security. The wait is over: today we’re rolling out Voice Calls in Western Europe. The rest of the world will get them very soon as well. The Voice Call interface is familiar and easy to use, but as always, you get loads of innovation under the hood with Telegram. Click Here to Watch Video Secure Telegram Calls are built upon the time-tested end-to-end encryption of Telegram's Secret Chats. The key verification UI we came up with in 2013 to protect against man-in-the-middle attacks served well for Telegram (and for other apps that adopted it), but for Calls we needed something easier. That‘s why we’ve improved the key exchange mechanism. To make sure your call is 100% secure, you and your recipient just need to compare four emoji over the phone. No lengthy codes or complicated pictures! Key verification Super-Fast Whenever possible, your calls will go over a peer-to-peer connection, using the best audio codecs to save traffic while providing crystal-clear quality. If a peer-to-peer connection can't be established, Telegram will use the closest server to you to connect you with the person you’re calling in the fastest way possible. Unlike other apps, Telegram has a distributed infrastructure all over the world which we’ve already been using to deliver your texts faster than other apps. Now these servers will also be used for calls. In the coming months, we’ll be expanding our content delivery network around the globe, getting the connection up to light-speed even in remote areas. AI-Powered Each time you make a Voice Call on Telegram, a neural network learns from your and your device‘s feedback (naturally, it doesn’t have access to the contents of the conversation, it has only technical information such as network speed, ping times, packet loss percentage, etc.). The machine optimizes dozens of parameters based on this input, improving the quality of future calls on the given device and network. These parameters can also be adjusted during a conversation if there's a change in your connection. Telegram will adapt and provide excellent sound quality on stable WiFi — or use less data when you walk into a refrigerator with bad reception. According to our tests, Telegram Calls are already superior to any of our competitors on comparable connections. But the quality of Telegram Calls will further improve as you and others use them, thanks to the built-in machine learning. Complete Control If you’re like us, you don’t like to be bothered. On Telegram, you can control who can and who can't call you with granular precision. You can even switch voice calls off altogether, blocking anyone and everyone from calling you. Privacy settings for calls By default, Telegram calls are lightweight and automatically adapt to the speed and type of your connection, so as to consume the least data possible. But if you want to reduce your data spending by another 25-30% at the expense of sound quality, you’re welcome to enable the Use Less Data option in Data and Storage Settings. No Added Calories Telegram is the most powerful messaging platform out there, but it is also famous for being the easiest one to use. We want to keep things this way, and that’s why by default we won’t clutter your screen with additional tabs and redundant buttons. Once you start making calls, Telegram for iOS will offer you to add a dedicated tab for calls on the main screen of the app. Alternatively, you can turn the Calls tab on right away from the Recent Calls section in Settings. On Android, the call tab is accessible via the pull-out main menu on the left. It‘s always easy to make a call, even if you’ve never opened the calls tab. As soon as Voice Calls are enabled for your country, a phone icon will appear on every profile page. On Android, you can also call from the ‘…’ menu in a chat and choosing ‘Call’ on iOS. On Android, the Call button is in the ‘…’ menu at the top. New call button One more thing For those of you who don’t do voice calls, v.3.18 brings something different: direct control over the quality of videos you share. Use this brand-new setting to select the degree of compression before sending a video. For the first time in the history of messaging, you can preview how the recipient will see your video before you send it. Click Here to Watch Video The app will remember the compression rate you selected and will use it by default for your future video uploads. And that‘s it for today. Stay tuned, there’s always more coming!

  14. WhatsApp and Telegram fix big vulnerability WhatsApp and Telegram have patched critical flaws in their apps that could allow attackers to gain control over user accounts. According to researchers from Check Point Software Technologies, they discovered issues with the way the two apps process several types of files without checking to see if they contain malicious code. They mention that the online versions of these platforms - WhatsApp Web and Telegram Web - mirror all messages sent and received by the user, being fully synced with the smart device. If exploited, the vulnerability they found could allow attackers to completely take over users' accounts on any browser, access their personal and group conversations, photos, videos and other shared files, as well as contact lists and basically any other information they share with the app. That translates into someone stealing your photos, sending messages in your name, demanding ransom, and so on. So how does this work? Well, it all starts with the attacker sending a file that looks innocent to the victim, but which contains malicious code. The file can be easily modified to make sure the victim takes the bait and opens it. Once it is opened, the attacker can go ahead and "own" the account. "Since messages were encrypted without being validated first, WhatsApp and Telegram were blind to the content, thus making them unable to prevent malicious content from being sent," researchers note in their post. The vulnerability was disclosed to WhatsApp and Telegram last week, and they've both rolled out updates for their web clients soon after. All users need to do to get the update is restart their browser, so it's probably safe to say everyone is now protected. The impact of this bug is massive. WhatsApp has over 1 billion users worldwide, and Telegram has another 100 million monthly users. It's unknown at this point what percentage of these numbers use the web platforms provided by the apps. The technical details In the case of WhatsApp, Check Point researchers managed to bypass the restrictions set by the app's mechanism by uploading a malicious HTML document with a legitimate preview of an image to fool a victim into thinking they were clicking on a link to view a cool cat picture, or whatever else may interest them. Once the victim clicks on the document, the URL is accessed and users can say good-bye to their accounts. "Once he clicks on the file, the victim will see a funny cat under blob object which is an html5 FileReader object under web.whatsapp.com. That means the attacker can access the resources in the browser under web.whatsapp.com," the post reads. The user doesn't have to do anything else because just clicking on the link makes the victim's local storage data available to the attacker. Via a JavaScript function that checks frequently for new data, the local storage is replaced with the victim's. The attack on Telegram works pretty much the same with the attackers having to bypass the upload policy in order to upload a malicious HTML document with a mime type of a video file. Once the file is accessed, the attacker can get its hands on the users' data. Thankfully, however, this problem has been fixed. It is unknown if anyone else picked up on the problem before it was reported to the two companies. "This flaw shows how difficult it is to balance security and usability. WhatsApp did the right thing by encrypting the content, but by doing it too early in the message analysis pipeline, they could not determine that a message might be crafted to contain malicious code. This code could then access malicious information, which could be used to log into a user’s account for the web application. This flaw could be easily mitigated by using 2-factor authentication (recently introduced by WhatsApp), which has been proven to be one of the best security mechanisms to prevent wide-spread compromise," said Professor Giovanni Vigna, co-founder of malware detection firm Lastline. “As the bad guys get smarter our applications need to keep up. More and more of our communications are open to abuse from cybercriminals and the opportunistic eaves dropper. One of the ways to get around this process is using something called end-to-end message encryption. WhatsApp states that “When end-to-end encrypted, your messages, photos, videos, voice messages, documents, status updates and calls are secured from falling into the wrong hands.” I.e. I encrypt it (automatically) from my application before I send it and you decrypt it at your end when you receive it. That means if anyone compromises the data in transit they are unable to use or identify anything within it, and there lies the problem - it limits your options for checking for anything malicious. Luckily this only affected the web platform so once resolved by WhatsApp themselves it only requires a browser restart," added Mark James, security specialist at ESET. Updated to include expert commentary. Source
  15. Telegram Crammed: Hackers Find Way To Send Massive Messages Mobile data annihilated. Researchers have found what they say is a flaw in the Telegram that allows messages of any size to be sent. The unpatched flaw demonstrated in a proof-of-concept shows how attackers can send messages of any size over the popular encrypted communications app by skirting restrictions. Telegram has been contacted for comment. Iranian researcher Sad Ghaf did not pinpoint the flaw in a bid to prevent others exploiting it, and says he could not find a way to report the flaw to Telegram. "Due to a programming error [a] sender can gain control of the size of messages and send them with arbitrary length," Ghaf says. "On the other side [the] victim would receive all incoming messages even if they are too long." Ghaf and his fellow researchers were able to send a message with 30000 bytes, exceeding the 4096 byte limit, and another which was empty breaching the one byte minimum. Messages can be sent to anyone without pre-authorisation meaning attackers could drain victim's mobile data allowances, and fill up phone storage with junk data.

How To Hack WhatsApp Using SS7 Flaw Researchers are easily able to hack WhatsApp and Telegram using the known telecom flaw We continuously receive queries from readers about how to hack WhatsApp. The world’s most popular cross platform messaging App is seen to be ultimate hack by many because it has recently enabled 256-bit encryption. For ordinary souls this encryption would take days and months to decode a sentence or a complete message. Ditto with another secure messaging service called Telegram. Though Telegram is not as popular as WhatsApp, it has its ardent group of followers who use it for its encryption as well as snooping free service. Though both of these Apps are end-to-end encrypted both of them suffer from hardware side vulnerability which can be exploited to hack and hijack both WhatsApp and Telegram. The vulnerability lies in Signalling System 7, or SS7, the technology used by telecom operators, on which the highly secure messaging system and telephone calls rely. SS7 is a set of telephony signalling protocols developed in 1975, which is used to set up and tear down most of the world’s public switched telephone network (PSTN) telephone calls. It also performs number translation, local number portability, prepaid billing, Short Message Service (SMS), and other mass market services. SS7 is vulnerable to hacking and this has been known since 2008. In 2014, the media reported a protocol vulnerability of SS7 by which both government agencies and non-state actors can track the movements of cell phone users from virtually anywhere in the world with a success rate of approximately 70%. In addition, eavesdropping is possible by using the protocol to forward calls and also facilitate decryption by requesting that each caller’s carrier release a temporary encryption key to unlock the communication after it has been recorded. Researchers created a tool (SnoopSnitch) which can warn when certain SS7 attacks occur against a phone and detect IMSI-catchers. You can view how researchers managed to hack WhatsApp and Telegram using the SS7 flaw below : WhatsApp Hack Telegram Hack Both the hacks exploit the SS7 vulnerability by tricking the telecom network into believing the attacker’s phone has the same number as the victim’s phone. Once the network has been fooled, anybody, even a newbie can spy on the legitimate WhatsApp and Telegram user by creating a new WhatsApp or Telegram account using the secret code. Once complete, the attacker now controls the account, including the ability to send and receive messages. Even more horrific is the fact that the hacker can also send messages on behalf of the victim, and read confidential messages intended for the victim without ever having to try to break strong encryption protocols. See how easily you can hack WhatsApp and Telegram by fooling the network into believing your are the victim. Source
  17. TorrZan is a new service that allows Telegram users to download torrents through their favorite instant messaging application. The Telegram bot can find files on popular torrent sites and downloads them securely through its service. When the transfers are complete, users can download or play the files directly through the instant messaging service. With 100 million active users, Telegram is one of the most used messaging services, but it’s much more than that. The application, which is supported by all leading operating systems, also allows developers to create nifty bots. This can come in quite handy. The new TorrZan bot, for example, can grab torrents directly from the messaging application. With a series of simple commands it’s easy to find or add popular torrents, which can then be downloaded with a simple click. The torrent files are not shared over the user’s local network, but from TorrZan’s servers. Once a download is complete the files can be downloaded to a local device, or played directly if they are streamable. We tried the free version, which allows people to test three torrents up to 10GB without speed restrictions. Downloading a copy of the film Sintel took just a few minutes and after it was completed an https link to the mp4 video played seamlessly on both iPhone and PC. The developers of TorrZan say they created the service to provide an easy and convenient tool for people to download torrents, while keeping user privacy in mind. “We created this bot only because we believe that it is the most convenient and easiest way to download torrents across all platforms that are supported by Telegram, which includes Android, iOS, Windows Phone, PC, Mac and Linux,” TorrZan’s team informs TorrentFreak. TorrZan doesn’t record or store any logs of your downloading activity, which is good to know. As an added privacy bonus, it uses external servers to download the torrents so users’ local IP-addresses are not visible to the public. Besides adding torrents or magnet links manually, users can also use the bot to search for files. This appears to work nicely for well-known titles, and avoids the extra step of having to search for links on third-party sites. “We integrated a search feature that displays torrents from popular torrent sites right inside our bot. This means that our users don’t have to jump through hoops, they can simply find torrents and download them directly inside the same interface,” the TorrZan team says. The bot is still in the early stage of development and the team is planning to introduce several new features and updates in the future. Among other things, they want to make it easier to integrate video and audio playback with local devices. For now, anyone can test the service for free without any restrictions. However, the services uses a freemium model and after three torrents non-paying users are limited to 1 GB of storage and a 50 KB\s download limit. Those interested in giving it a free spin can visit the official TorrZan site. Article source
  18. TEHRAN (Tasnim) – Iran’s Cyber Police Chief General Kamal Hadianfar said Russian instant messaging service Telegram should move its servers to Iran if it seeks to continue its operation in the country. Currently, the majority of cases dealt with in Iran’s cyber police department are related to the activities of terrorist groups – including the Persian channel of Daesh – and ethical crimes in Telegram, General Hadianfar announced in a press conference here in Tehran on Monday. The lawsuits filed in Iran’s cyber police this year indicate that 20 percent of crimes were committed in mobile messaging services like Viber and Telegram, he explained, adding that Telegram has accounted for 40 percent of such crimes. Therefore, he added, Telegram is obliged to transfer its servers to Iran’s territory based on global regulations. Hadianfar, however, noted that Telegram’s CEO has announced the company is not able to transfer the servers due to anti-Iran sanctions, while it is indeed operating in Iran’s cyberspace in spite of such embargos. Iranian ministry of communications and the Interpol are currently following up on Iran’s requests from Telegram, he noted, adding that if the company is willing to continue its operation in Iran, it has to move its servers to somewhere inside the country. General Hadianfar also announced that Iran’s Cyber Police has managed to arrest 53 webmasters and owners of websites and pages that supported the Daesh (ISIL) terrorist group. The majority of these people, he said, were living in border areas or border provinces of Iran. The Daesh terrorist group is known for recruiting young people from around the world by the extensive use of social media and cyberspace, but Iranian police has frequently highlighted the country’s readiness to counter any type of terrorist threat, including those in the cyberspace. The Takfiri group has recently launched a Persian language channel in Telegram messenger. Telegram has been recommended by Daesh to its supporters and in October 2015 they were able to double the number of followers of their official channel to 9,000. In November 2015, however, Telegram announced that it had blocked 78 channels linked to Daesh, based on reports to the company’s abuse email. It came while Telegram’s CEO Pavel Durov had stated in September that he had no issues with terrorists using the app, as privacy is paramount and terrorists will always find another way to communicate. Telegram’s public channels allow broadcasting messages to an unlimited number of people and were used by the terrorists to spread propaganda. Telegram’s usage by Daesh for propaganda purposes has reignited the encryption debate. However, Iran hasn’t had an international content distribution network and Ali Ansari, Iran's deputy IT organization has recently announced plans underway to launch content distribution centers (CDN) across the country. Content distribution network with local target traffic, increase quality and efficiency of broadband Internet services. He also said that despite CDN centers it’s possible to manage the amount of bandwidth consumed there. Ansari said content distribution centers increase quality of service and bandwidth savings because they will have local servers with traffic. He also announced the availability of international CDNs with the purpose of transferring foreign web hosting to Iran and said: by having international CDNs in Iran it will be easier to host popular foreign websites in Iran.
