Russian SVR-linked hackers use Anthropic's Claude AI in cyberattacks on Ukraine

Anthropic reports that Russian intelligence-linked threat groups, including SVR-affiliated Midnight Blizzard, used its Claude AI tool in multi-victim campaigns against Ukrainian government ministries, diplomatic missions, and military drone supply chains. The company disrupted operations over six months, marking a notable first use of commercial AI by state-aligned actors in this context. This signals an evolving cyber threat landscape where AI tools are weaponized for espionage, with implications for Western institutions.
