Zcrypt is a newly discovered ransomware sample that security vendor Check Point profiled in a report this week. Zcrypt uses older techniques along with new ones in order to propagate and evade detection by anti-malware tools. It is designed to overwrite targeted files not once, but twice; Zcrypt does not attempt to delete shadow copies, delete itself, or copy itself several times before initiating, she says. The mix of older techniques in Zcrypt suggests that ransomware purveyors are trying different tacks to sneak their malware past malware defenses.”]
