Un inquiétant cheval de Troie très discret et multiplateformes vient d'être repéré. Baptisé SysJoker et mis en lumière par la firme de sécurité Intezer, il peut cibler autant Windows, Linux que macOS. Pire encore, celui-ci passait sous les radars des antivirus depuis un bout de temps. Les versions Linux et macOS n'étaient jusqu'à présent pas du tout détectées par des sites

Never-before-seen, cross-platform SysJoker came from an "advanced threat actor."

In December 2021, we discovered a new multi-platform backdoor that targets Windows, Mac, and Linux that we have named SysJoker.

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
