A massive malware campaign pushed the Java-based STRRAT remote access trojan (RAT), known for its data theft capabilities and the ability to fake ransomware attacks. Microsoft Security Intelligence team outlined how this “massive email campaign”” spread the fake ransomware payloads using compromised email accounts.

The malware is designed to fake a ransomware attack while stealing its victims’ data in the background.”
