Jinse Finance reported that artificial intelligence company Anthropic stated that hackers have used Anthropic's technology to carry out a large-scale cybercrime operation, affecting at least 17 institutions. This is an "unprecedented" case of attackers weaponizing commercial AI tools on a large scale. According to Anthropic's report, the hacker used Anthropic's agent-based coding tool Claude Code to launch data theft and extortion attacks against government, healthcare, emergency services, and religious institutions over the past month, resulting in the leakage of medical data, financial information, and other sensitive records. The ransom demands ranged from $75,000 to $500,000, to be paid in cryptocurrency.
