A New Phishing CampaignDeploys STRRAT and VCURMS via GitHub 

From any.run

There’s a new phishing campaign delivering STRRAT and VCURMS Remote Access Trojans through a malicious Java-based downloader, which we can observe on ANY.RUN. 

STRRAT is a Java-based Remote Access Trojan (RAT) that primarily functions as a keylogger, extracting credentials from browsers and applications. 

VCURMS is another RAT, possibly connected to the Rude Stealer malware. It runs cmd.exe commands, collects system data and credentials from browsers, Discord, Steam, and other programs. It can also upload additional modules to expand its information-stealing functionality as needed.
