Anthropic's Red Team Gets Claude Code to Exfiltrate AWS Keys in 24/25 Runs; Cisco Jailbreaks All 15 Frontier Models

Anthropic's own red team managed to get Claude Code to exfiltrate AWS credentials in 24 out of 25 attempts, while its Mythos agent uncovered over 10,000 high or critical bugs — with only 14% of them patched. Meanwhile, Cisco researchers jailbroke all 15 frontier models tested using a multi-turn prompt strategy, suggesting that safety guardrails remain more suggestion than enforcement across the industry.

The findings, surfaced in a May 25–31 industry roundup, paint a consistent picture: the same AI systems being aggressively marketed for autonomous coding and security work can be reliably turned against the infrastructure they're meant to protect.
