Anthropic: Russia-linked hackers used Claude Code to automate cyberattacks on Ukraine and Europe
Anthropic published a report documenting how a cyber actor tracked as GTG-20006 — linked by researchers to the Russian group Midnight Blizzard — used the company's Claude Code AI tool to automate large portions of cyberattacks against Ukrainian and European government, defense and diplomatic targets.
