The hackers within the Kaseya marketing campaign dropped an outdated file model that remained weak to the side-loading of “msmpeng.exe,” which is the file for the Home windows Defender executable.

Federal prosecutors allege that Vasinskyi triggered the deployment of malicious Sodinokibi/REvil code all through Kaseya’s software program construct system to additional deploy REvil ransomware to endpoints on buyer networks.
