NB65 is an Anonymous-affiliated hacktivist group that targeted Russian organizations in retaliation for Russia’s 2022 invasion of Ukraine. Its activities include network breaches, data theft, publication of stolen information, disruption of television broadcasters, and ransomware deployment. Its targeting has included Russian public-sector entities and state-owned broadcasting organizations. Around late March 2022, NB65 expanded from data theft and disclosure operations to ransomware attacks using a modified encryptor derived from leaked Conti source code. Technical analysis identified substantial code overlap between its ransomware and Conti. NB65 framed its operations as efforts to disrupt Russia’s ability to operate normally and stated that it would cease attacks when Russia ended hostilities in Ukraine. Although it issued ransom demands, its stated objectives were political rather than primarily financial.
