Researchers warn of a new strain of ransomware dubbed Rorschach that doesn’t appear to be related to previously known threats and uses several unique features in its implementation, including one of the fastest file encryption routines observed so far.
“A behavioral analysis of the new ransomware suggests it is partly autonomous, spreading itself automatically when executed on a domain controller (DC) while it clears the event logs of the affected machines,” researchers from security firm Check Point said in a new report. “In addition, it’s extremely flexible, operating not only based on a built-in configuration but also on numerous optional arguments which allow it to change its behavior according to the operator’s needs.”
