Sysjoker: What is this undetectable malware targeting macOS, Microsoft, and Linux?

This remains a mystery to cybersecurity professionals. Since December, malware called SysJoker has ravaged Windows, macOS, and Linux systems. Its level of sophistication indicates that high-profile hackers will be behind it.

Above all, malware is still rarely designed and coded to attack the three known operating systems on computers. In fact, SysJoker will exploit the backdoor to install itself without the knowledge of users of infected devices. Even the latest cybersecurity and antivirus software fails to detect any anomalies in affected computers.

However, according to research conducted by the company INTERSER Whoever detected this malware, SysJoker could be a system used for electronic espionage, since it contains all the undetectable program guides that are useful for recovering information without leaving any traces.

The researchers who discovered it believe that SysJoker can accompany an update to hack the target computer. Once installed on the computer, the malware will connect to Google Drive to download information and especially tools that allow other software to be installed without the device user’s knowledge, and takes over remote control.

According to the first elements of Intezer’s investigation, SysJoker could have been created quite recently, within the past six months. However, researchers have not yet been able to note any malicious uses or cases reported by victims. Perhaps its undetectable side explains the lack of information.
