A Russian-speaking threat actor known as \u201cTrim\u201d has reportedly transformed jailbroken frontier AI models<\/a> into an automated penetration testing platform called AI Pentest Checker.<\/p>\n This activity highlights how criminals can misuse legitimate AI services and common security tools to accelerate reconnaissance, validate vulnerabilities, and create reports.<\/p>\n According to Cato reports, Trim first appeared on a Russian-language cybercrime forum on March 13, 2026, where he shared methods claimed to bypass Claude Opus<\/a> safety controls.<\/p>\n The actor allegedly described techniques for prompt-based manipulation designed to make a model treat offensive requests as authorized security research instead of malicious activity.<\/p>\n The reported methods included creating a benign context before making a harmful request, reframing instructions to focus only on code structure, and retrying softened versions of previously refused prompts.<\/p>\n These techniques are forms of \u201cjailbreaking,\u201d where an attacker attempts to override a model\u2019s behavioral safeguards through crafted inputs rather than exploiting the underlying infrastructure.<\/p>\n Threat researchers have already observed the criminal misuse of legitimate large language models (LLMs)<\/a>, including jailbreaking. Trim also reportedly recommended alternative AI services and locally hosted models when commercial systems refused a request.<\/p>\n This strategy lowers dependency on any single AI provider, giving threat actors a fallback option for generating code, analyzing targets, or creating exploitation content.<\/p>\n Research groups warn that increasingly capable frontier models can support offensive tasks, such as vulnerability analysis and exploit-related activities, even when providers implement safety controls.<\/p>\n Cato Networks reported <\/a>that Trim allegedly promoted AI Pentest Checker on June 21, combining AI capabilities with offensive security tools for automated testing.<\/p>\n The tool reportedly integrates scanners and reconnaissance tools such as Nuclei, ffuf, katana, subfinder, and Gitleaks to automate target discovery, endpoint enumeration, secret detection, and vulnerability checks.<\/p>\n The concern is not that these utilities are inherently malicious legitimate penetration testers and defenders widely use them.<\/p>\n However, when combined with a jailbroken AI assistant, these tools can reduce the time and expertise needed to coordinate an intrusion workflow, interpret scan results, prioritize findings, and produce polished reports.<\/p>\n The platform reportedly used Claude Opus in its critical vulnerability escalation process and another model for generating exploitation reports.<\/p>\n Claims that a modified system prompt from a \u201cFable 5<\/a>\u201d configuration was used should be treated cautiously unless independently verified.<\/p>\n However, exposed or leaked system prompts can provide attackers insight into a model\u2019s instructions, helping them test prompt-injection or jailbreak strategies more effectively.<\/p>\n This case reflects a larger shift in the threat landscape. AI is evolving from a writing assistant for cybercriminals to an operational layer that can organize multi-step attack workflows.<\/p>\n Anthropic has previously reported disrupting cybercriminal activities in which AI was used for tasks ranging from target research to intrusion support and extortion-related work.<\/p>\n Organizations should respond by reducing their exposed attack surface, continuously scanning internet-facing assets, enforcing multifactor authentication (MFA), rotating compromised credentials, and monitoring for abnormal reconnaissance activity.<\/p>\n Security teams should also consider AI-generated phishing, automated vulnerability research, and faster exploit development as realistic risks rather than future scenarios.<\/p>\n The Privilege Paths Attackers See That You Don\u2019t: BeyondTrust Pathfinder Platform Does It for You ->\u00a0Get Free Identity Security Assessment<\/a><\/strong><\/strong><\/p>\n The post Russian Hacker Jailbreaks Claude to Turn into an AI-Powered Penetration Testing Platform<\/a> appeared first on Cyber Security News<\/a>.<\/p>\n<\/div>\nRussian Hacker Jailbreaks Claude<\/strong><\/h2>\n
