According to G DATA, STRRAT is a Java-based RAT, which makes extensive use of plugins to provide full remote access to an attacker, as well as credential stealing, key logging and additional plugins. The RAT has a focus on stealing credentials of browsers and email clients, and passwords via keylogging. It supports the following browsers and email clients: Firefox, Internet Explorer, Chrome, Foxmail, Outlook, Thunderbird.
Older version of the malware came with a rudimentary ransomware module that appends ".crimson" to affected files. The affected files are not encrypted, but simply reamed. If the extension is removed, the files can be opened as usual.
As of at least version 1.5, STRRAT has an implemented encryption routine.
