Snake Keylogger (a.k.a. 404 Keylogger) is a subscription-based keylogger that has many capabilities. The infostealer can steal a victim's sensitive information, record keystrokes, take screenshots, and extract information from the system clipboard. It was originally published on a Russian hacking forum in August 2019. It is notable for its relatively unusual data exfiltration methods, including via email, FTP, SMTP, Pastebin or the Telegram messaging app.
