Earlier today (January 11th), Researchers at Intezer published an report titled, “New SysJoker Backdoor Targets Windows, Linux, and macOS.”

In this report, they detailed a new cross-platform backdoor they named SysJoker. Though initially discovered on Linux, the Intezer researchers shortly thereafter also found both Windows and Mac versions:

"SysJoker was first discovered during an active attack on a Linux-based web server of a leading educational institution. After further investigation, we found that SysJoker also has Mach-O and Windows PE versions." -Intezer
