duddy posted a topic in Security & Privacy NewsIoT Devices At Major Manufacturers Infected With Crypto-Miner Security experts from TrapX reported that some IoT devices running Windows 7 have been infected with a piece of malware, is it a supply chain attack? The experts reported that several IoT devices at some major manufacturers have been infected with a cryptocurrency miner in October 2019. The list of infected devices includes automatic guided vehicles, a printer, and a smart TV. “The malware sample intercepted and analyzed by TrapX® is part of the Lemon_Duck sample family running on a double-click action or through persistence mechanisms.” reads the report published by TrapX.”First, the malware scanned the network for potential targets, including those with SMB (445) or MSSQL (1433) services open. Once finding a potential target, the malware ran multiple threads with multiple functionalities.” According to the experts, the attacks could part of the same malware campaign, the infections were observed in over 50 sites of the manufacturers in the Middle East, North America, and Latin America. Attackers employed downloader that runs malicious scripts associated with a cryptocurrency miner named Lemon_Duck. The researchers explained that the malware rapidly spread and is considered for this reason as “extremely disruptive.” “Once again, the entry point was a device running Windows 7. The campaign caused confusion on the production line possibly damaging products AGVs assemble. The malware spread quickly enough to be extremely disruptive.” continues the report. “TrapX softwaware provided early breach detection and allowed the security team to immediately disconnect the infected AGV from the network before severe damage could occur.” The malware infected embedded systems running Windows 7, but the popular Microsoft OS reached the end of life in January. This incident is worrisome because there are hundreds of millions of systems worldwide that run on top of the Windows 7 operating system. The report includes a description of the attacks detected by the experts, for example, several automatic guided vehicles (AGVs) that were running Windows 7 were found infected at one manufacturing site. In another case presented by TrapX, the malware was found on a DesignJet SD Pro multifunction printer that had been used to print technical engineering drawings containing sensitive data related to the target’s production process. In this case, the device was used by attackers as the entry point into the target’s network. TrapX experts speculate the cases were the result of a supply chain attack, this means that the malware was installed on the devices before they were deployed in the manufacturers’ sites. Additional details, including Indicators of Compromise (IoCs) are reported in the analysis published by TrapX. Source
steven36 posted a topic in Security & Privacy NewsOne of the biggest disadvantages of using pirated software is the increased risk of letting your computer get infected with malware. Cybercriminals often bundle the cracked versions of paid software on piracy websites with adware and cryptominer to earn free cash. So, if you’re installing such programs from unknown sources, the chances of you getting hacked are pretty good. The same attack vector is being used by hackers to distribute a new Mac cryptocurrency miner named Bird Miner. As Malwarebytes’ official blog explains, Bird Miner has been found to be bundled with a cracked installer of a software named Ableton Live, which is a tool for high-end music production. Malwarebytes found that Ableton Live 10’s cracked 2.6 GB installer is available on piracy website VST Crack. Security researchers from the firm became suspicious when they found that Bird Miner’s post installation script was busy copying installed files to new locations with random names. The new files with random names seem to have various functions, including the role of launch daemons. One such daemon launches a shell script called Crax, which makes sure that the malware is hidden from the security researchers. The malware further checks to see if your Mac’s CPU is operating at more than 85 percent load to avoid running the cryptomining script in this case. Bird Miner uses Tiny Core Linux emulation The last piece of the puzzle is the launch of an executable named Nigel, which is an old version of an open source emulator named Qemu. For those who don’t know, Qemu is a terminal-only virtualization software that lets one run Linux packages on non-Linux machines. The Qemu emulator further uses a file named Poaceae, which is a bootable Tiny Core Linux image. Finally, as soon as the Tiny Core system boots up, the xmrig miner starts running to mine the Monero cryptocurrency. The Malwarebytes researchers mention that familiarity with Linux could be the reason why creators of the malware chose the Linux route. This malware further shows why using pirated software increases the chances of getting infected very easily. Source
