nitrogen

Executive Summary

Nitrogen is a medium-sophistication cybercriminal threat group initially identified as a malware loader in 2023, evolving into an independent ransomware operator by mid-2024. Specializing in double-extortion attacks and leveraging Eastern European infrastructure, Nitrogen operates its own strain derived from leaked Conti 2 builder code.

Goals & Targeting

Nitrogen's strategic objectives are centered on maximizing financial gains through ransomware campaigns. The group targets sectors tied to Eastern European critical infrastructure, likely due to higher payouts and potential for coercion. Their targeting profile reflects a focus on organizational vulnerabilities that facilitate quick payment of ransoms after encryption.

Nitrogen emerged as a malware loader delivering BlackCat/ALPHV ransomware before evolving into an independent operator by mid-2024. The group developed its own ransomware strain using leaked Conti 2 builder code, focusing on double-extortion tactics and targeting primarily Eastern European infrastructure. Known for its criminal motivations centered around financial gain, Nitrogen has been active since March 2023 through June 2026, with over 46 known victims and at least two ransom notes recovered.
