Researchers have spotted, threat actors have deployed a new ransomware strain using the Palo Alto Cortex XDR Dump Service Tool, a commercial security product and it’s dubbed as Rorschach.
Unlike other ransomware cases, the threat actor did not hide behind any alias and appears to have no affiliation to any of the known ransomware groups. Those two facts, rarities in the ransomware ecosystem, piqued CPR’s interest and prompted us to thoroughly analyze the newly discovered malware.
The ransomware is highly customizable and contains technically unique features, such as the use of direct syscalls, rarely observed in ransomware. Moreover, due to different implementation methods, Rorschach is one of the fastest ransomwares observed, by the speed of encryption.
