Severity

Medium

Analysis Summary

Snake is a modular .NET keylogger that was first spotted in late November 2020. Snake malware’s main feature is keylogging, but it also has additional capabilities such as taking screenshots and extracting data from the clipboard. Snake can also extract and exfiltrate data from browsers and email clients. 
Snake’s name was derived from strings found in its log files and string obfuscation code. Using the malware’s builder, a threat actor can select and configure desired features and then generate new payloads. For this reason, the capabilities of samples found in the wild can vary.
