Summary
Researchers have uncovered a never-before-seen backdoor written from scratch for systems running Windows, macOS, or Linux that remained undetected by virtually all malware scanning engines.Researchers from security firm Intezer said they discovered SysJoker—the name they gave the backdoor—on the Linux-based Webserver of a “leading educational institution.” As the researchers dug in, they found SysJoker versions for both Windows and macOS as well. He also found that the macOS file was digitally signed, though with an ad-hoc signature.SysJoker is written in C++, and as of Tuesday, the Linux and macOS versions were fully undetected on the VirusTotal malware search engine.
