The StreamScan report provides limited public information on Nitrogen's tactics, including key indicators of compromise such as a malicious executable's SHA-256 hash and a unique mutex identifier.

First identified in September 2024, Nitrogen ransomware poses a significant threat to financial firms in the US, UK, and Canada.

Nitrogen exploits the legitimate driver truesight.sys to disable antivirus protections, enabling it to operate undetected and manipulate system settings, including disabling Windows Safe Boot.

This ransomware encrypts critical data and demands large payments for decryption, impacting various industries such as finance, construction, manufacturing, and technology.

Cybersecurity experts have highlighted Nitrogen's advanced tactics, including malvertising on search engines and the use of trojanized software installers to infiltrate networks.

ANY.RUN offers threat intelligence services that assist organizations in proactively monitoring for indicators of compromise and enhancing defenses against ransomware attacks like Nitrogen.

Notable victims of Nitrogen include SRP Federal Credit Union in the US, attacked in December 2024, and Red Barrels in Canada, which had 1.8 terabytes of sensitive data extorted.

Once inside a network, Nitrogen employs tools like Cobalt Strike and Meterpreter to maintain persistence and execute its malicious payload, using evasion techniques to avoid detection.

To combat the threat posed by Nitrogen, organizations are advised to block known malicious infrastructure, monitor unusual system activity, educate employees on phishing, and regularly update software to patch vulnerabilities.
