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. The Snake Keylogger malware is typically delivered to target systems via malicious email attachments, infected software downloads, or drive-by downloads. Once installed on a system, the malware operates in the background and collects information as the user interacts with their computer. The collected data is then transmitted to the attacker, allowing them to access sensitive information.
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.
To protect against snake keyloggers, it is important to use antivirus software and keep it up to date. It is also important to be cautious when opening email attachments or downloading software from unknown sources. Additionally, using strong and unique passwords for all accounts can make it more difficult for a keylogger to obtain sensitive information.

Remediation
- Block all threat indicators at your respective controls.
- Search for indicators of compromise (IOCs) in your environment utilizing your respective security controls.
- Emails from unknown senders should always be treated with caution.
- Never trust or open " links and attachments received from unknown sources/senders.
- Passwords - Ensure that general security policies are employed including implementing strong passwords, correct configurations, and proper administration security policies.
- Admin Access - limit access to administrative accounts and portals to only relevant personnel and make sure they are not publicly accessible.
- Patch and upgrade any platforms and software timely and make it into a standard security policy. Prioritize patching known exploited vulnerabilities and zero-days.
- Enable antivirus and anti-malware software and update signature definitions on time. Using multi-layered protection is necessary to secure vulnerable assets.
