Microsoft has released an alert today warning about a new ransomware variant called ZCryptor, which comes with the ability to self-propagate via removable and network drives.
A security researcher named Jack, behind the MalwareForMe blog, first discovered and wrote about this threat on May 24. Three days later, Microsoft 's security team also took note of the new wave of infections.
“We are alerting Windows users of a new type of ransomware that exhibits worm-like behavior,” Microsoft's Malware Protection Center alert reads. “This ransom leverages removable and network drives to propagate itself and affect more users.”
