404 Keylogger, Snake Keylogger Snake Keylogger (aka 404 Keylogger) is a subscription-based keylogger that has many capabilities. The infostealer can steal a victims sensitive information, log keyboard strokes, take screenshots and extract information from the system clipboard. It was initially released on a Russian hacking forum in August 2019. It is notable for its relatively unusual methods of data exfiltration, including via email, FTP, SMTP, Pastebin or the messaging app Telegram.
