*Threat actors abused Anthropic's Claude Code and OpenAI models to automate exploit development and data theft, compromising at least 10 Mexican government agencies and a financial institution, exfiltrating more than 150GB of records and exposing approximately 195 million identities; attackers jailbroke Claude, issued over 1,000 prompts to bypass safeguards, and pivoted to ChatGPT when needed to deepen access and organize stolen credentials.*
