A hacker known as 'Trim' has created a commercial offensive AI pentesting platform by jailbreaking Claude Opus models. Trim first posted detailed jailbreak techniques on a Russian-language forum on March 31, 2026, and later launched the 'AI Pentest Checker' tool. The tool integrates multiple AI models with conventional scanning tools to automate web vulnerability assessments. Trim reportedly purchased a grey-market API key for $4 to access Claude Opus, demonstrating a growing trend in weaponizing AI for cybercrime. The platform can generate PDF reports in under 10 minutes after scanning a target domain. This operation highlights the evolving threat landscape where AI models are exploited for malicious purposes.
