This RAT was first identified at the German cybersecurity firm in June 2020. This malware uses plugins to grant the attacker remote access. STTRat steals login credentials from browsers and email clients, logs keystrokes, and exploits vulnerable Windows operating systems remotely. The malware adds the file extension (.crimson) to Notepad to show a bogus ransom message. STRRAT malware supports the browsers Firefox, Chrome, Foxmail, Outlook, Internet Explorer, and Thunderbird.
