  1. AI Code Security with Claude Mythos Preview: Inside Tenable’s 500+ Hours of Testing

Overview

  • Tenable conducted over 500 hours and processed more than 40 billion tokens testing Anthropic’s Claude Mythos Preview across various security tasks: source code analysis, exploit creation, binary reverse engineering, threat modeling, and dynamic testing.
  • Claude Mythos Preview produces a high volume of findings with substantial variance (up to 30% run-to-run variance in findings and severity).
  • The model is non-deterministic and costly to run continuously (~$500,000 per FTE per year estimated for full-time use).
  • The model finds existing classes of source code flaws faster and at greater volume but does not uncover new types of vulnerabilities.
  • Tenable emphasizes that combining frontier AI models with human expertise and traditional deterministic tools (SAST, DAST, SCA) enhances but does not replace existing code security programs.

Impact

  • Frontier AI models can dramatically scale security testing, increasing the speed and volume of potential vulnerability discoveries.
  • Noise and inconsistency in model findings present operational challenges, making it unsuitable as a sole source for audit-grade or compliance-focused vulnerability management.
  • Costs and expertise requirements currently limit frontier AI utility to targeted and periodic testing rather than continuous integration.

Recommendations

  • Use frontier AI models as an additional exploratory layer alongside deterministic security tools.
  • Ensure human oversight and validation pipelines accompany AI-generated findings to reduce false positives.
  • Protect source code repositories diligently to maintain the defender’s advantage of full source visibility.
  • Consider operational costs and adopt AI-driven testing selectively to manage total cost of ownership.
