According to ransomware.live, Nitrogen began as a malware loader in 2023 used to deliver BlackCat/ALPHV ransomware, then evolved into a fully independent ransomware operator by mid-2024, operating its own strain derived from leaked Conti 2 builder code and conducting double-extortion attacks primarily linked to Eastern European infrastructure.
