Ukraine Invasion Fuels Hacktivist Attacks and Darknet Data Leaks

Summary
DarkOwl’s February–April 2022 timeline tracks invasion-related cyberattacks, Russian data leaks, ransomware-group divisions and infrastructure warnings. Many hacktivist claims remain unverified, and some purported leaks contain older data.
Key points
- DDoSecrets published 222GB of Gazregion emails and corporate files submitted by Anonymous, nb65 and DepaixPorteur, according to the April 18 update.
- nb65 claimed it encrypted Russian bank JSC PSCB’s network with a modified Conti ransomware variant, stole over 1TB of financial and client data, and deleted backups.
- Continent Express acknowledged a cyberattack but said important data and booking systems were unaffected; DDoSecrets subsequently distributed over 400GB attributed to the attack, with leak details unconfirmed.
- DDoSecrets released approximately 1.97 million emails totaling 2TB from five Russian government and corporate organizations over three days in April.
- An April 13 joint US advisory warned of capabilities to compromise industrial control systems, including Schneider Electric and OMRON controllers and OPC UA servers.
- Conti’s support for Russia prompted internal divisions and leaks of private chats, infrastructure details and ransomware executables; the group later revised its public position.
- DarkOwl cautioned that some claimed breaches lacked corroboration or recycled older data. It also flagged a purported Russian propaganda directive as potentially fabricated after researchers identified signature mismatches.
