A group of researchers has discovered a never-before-seen backdoor malware that affects systems running Windows, macOS, or Linux, and has failed to be detected by virtually all malware scanning engines.
Malware is usually the constant concern of practically all users who use an electronic device. Are able to steal our personal data, access accounts to our subscriptions, hijack information from many companies and much more. Not all act in the same way, although we usually refer to them as viruses to describe any threat that endangers both our personal information and the proper functioning of our devices. The reality is that there are countless types of malware with different purposes.
Discovery of SysJoker
Researchers from the company Intezer security claim to have discovered a backdoor malware called SysJoker on the Linux-based web server of “a leading educational institution.” As the researchers dug deeper into the finding, they discovered that there were also versions of SysJoker on both Windows and macOS. It is suspected that the RAT (Remote Administration Tool) cross-platform was able to develop in the second half of last year.
This discovery is relevant for several reasons, first of all, a cross-platform malware It’s not very common, since most malware is usually written for a specific operating system. In this case the RAT was written from scratch and used four separate command and control servers. This aspect denotes that the people who developed it invested significant resources. On the other hand, it is also rare to find a linux malware never seen before.
Analysis of the version of Windows and macOS
Analysis of the Windows version by Interzer and the Mac version (by researcher Patrick Wardle) found that the malware provides advanced backdoor capabilities. The executable files on both operating systems had suffix .ts.
It has not yet been possible to determine how the malware was installed. There is a theory that it could have been installed through a npm package malicious or using a fake extension to camouflage the malicious installer. This would suggest that the infections were not the result of exploiting a vulnerability, but of tricking the user into installing.
Meanwhile, Patrick Wardle said that “the .ts extension may indicate that the file is masquerading as video transport stream content.” He also discovered that the macOS file was digitally signed, albeit with an ad-hoc signature.
SysJoker is written in C++ and, until now, the Linux and macOS versions had not been fully detected in the VirusTotal malware search engine. “The backdoor generates its control server domain by decoding a string retrieved from a text file hosted on Google Drive. During the time the researchers analyzed it, the server changed three times, indicating that the attacker was active and monitoring the infected machines.”
According to the analysis and evaluation by Interzer, SysJoker could be after very specific targets with the aim of “espionage together with lateral movement that could also lead to a ransomware attack as one of the next stages.”
The size of China’s computer industry has exceeded a third of a trillion dollars. Beijing has supplied more than 20 million servers to the market in six years
According to the Chinese Academy of Information and Communications Technology, over the past six years, Beijing has supplied the market with more than 20.91 million general purpose servers and 820 thousand servers based on artificial intelligence technologies.
The volume of China’s computer industry in 2022 amounted to more than $362.2 billion. This became known at the World Computer Conference 2023, which opened in Changsha, Hunan Province, Central China.
The conference is dedicated to the topic “Digitalization of the world to create a new era of change in the computer industry.” Its participants discuss issues such as digital infrastructure, artificial intelligence and smart society.
“The new generation of information and communication technology has changed the model of economic and social development,” said Zhao Zhiguo, chief engineer of the Ministry of Industry and Information Technology.
Apple beat everyone again. The A17 Pro SoC in the iPhone 15 Pro and Pro Max is manufactured using a 3 nm process technology and is capable of running modern computer games
Apple iPhone 15 Pro and 15 Pro Max smartphones are known to have received the A17 Pro SoC, and this is a very interesting platform that is currently unique on the market.
It’s worth starting with the fact that this is the first mobile single-chip system and, apparently, the first consumer chip in general, which is produced using the 3 nm process technology at TSCM facilities. Previously, information appeared on the Internet that Apple had purchased all orders for some time regarding this technical process.
The SoC configuration includes only six processor cores: two productive and four energy-efficient. There is also a 16-core NPU and a new six-core GPU. The last one is especially important here. Apple says this is the largest GPU redesign in iPhone history. Compared to the GPU in the Apple A16 Bionic, the new one is 20% faster. But at the same time, it supports hardware acceleration of ray tracing, and MetalFX Upscaling technology allows you to relieve the graphics core. And all of this together is enough to run full-fledged computer games on the new iPhone Pro: Resident Evil Village, Resident Evil 4 Remake, Death Stranding and Assassin’s Creed Mirage! Yes, we have yet to evaluate the quality of graphics, resolution, etc., but this takes mobile gaming to previously unprecedented heights.
WhatsApp native app for Mac released – with group calls
The team of the popular WhatsApp messenger has announced good news for Apple computer users – a native application for macOS has become available.
The new and improved WhatsApp app, which was released earlier in 2023 for Windows, is now available for macOS users, according to the developers.
Group video and audio calls are available for the first time in the new WhatsApp app for macOS. Up to 8 people can participate in video calls, and up to 32 people in audio calls. Users can also view the call history and receive notifications of incoming calls even when the application is closed, share files by simply dragging them to the chat, and so on.
The new app is now available for download on WhatsApp.com and will be coming to the App Store soon.
