VectorCertain LLC today announced that its SecureAgent governance platform has independently validated detection and prevention of 100% of autonomous multi-step AI exploitation attempts before execution. The announcement comes days after Treasury Secretary Scott Bessent and Federal Reserve Chair Jerome Powell convened an emergency meeting with CEOs of major U.S. banks to address cybersecurity risks posed by Anthropic's Mythos model, as reported by Bloomberg and CNBC.
The validation, part of VectorCertain's MYTHOS certification program, tested 1,000 adversarial scenarios across eight sub-categories of autonomous multi-step exploitation, including multi-vulnerability chaining, cross-system lateral movement, and long-range multi-session campaigns. SecureAgent achieved 100% recall (810 of 810 attacks detected and prevented) with 98.9% specificity and zero false negatives. The results are statistically certified at 99.65% lower bound using the Clopper-Pearson exact binomial method across 7,000 total scenarios.
Autonomous multi-step exploitation, as demonstrated by Anthropic's Mythos Preview, allows AI to chain multiple vulnerabilities into a complete attack sequence. Anthropic's Frontier Red Team documented Mythos autonomously exploiting a 17-year-old FreeBSD vulnerability and chaining four browser exploits to escape sandboxes, as detailed in their red team blog. A March 2026 study by Folkerts et al. (arXiv:2603.11214) found that AI models completed 22 of 32 steps in a corporate network attack autonomously, representing approximately six hours of expert human effort.
VectorCertain's CEO Joseph P. Conroy emphasized the structural limitations of existing EDR systems, which scored 0% on identity attack protection in MITRE ATT&CK Evaluations Enterprise Round 7 (MITRE ER7). SecureAgent's five-layer governance pipeline evaluates every AI agent action before execution, blocking exploit chains in under 10 milliseconds. The platform's 13 discrimination micro-models detect malicious intent even when individual actions use legitimate tools and valid credentials.
The company is offering a free Tier A External Exposure Report that discovers leaked non-human identities, exposed credentials, and MITRE ATT&CK coverage gaps without requiring customer access. This report leverages data from GitGuardian's State of Secrets Sprawl 2026, which found 29 million hardcoded secrets on public GitHub in 2025, and SpyCloud's 2026 Identity Exposure Report, which identified 18.1 million exposed API keys.
The validation results address the exact threat class that prompted the emergency regulatory meeting. As Conroy stated, 'Treasury Secretary Bessent and Fed Chair Powell didn't summon bank CEOs because autonomous multi-step exploitation is theoretical. They summoned them because it's a current capability that every EDR vendor scores 0% against.' SecureAgent is the only platform with validated data proving pre-execution governance can stop these exploit chains before the first action fires.
