Mythos SI identifies Temporal Trust Gaps in FFmpeg

Mythos SI, utilizing the Structured Intelligence framework, has discovered a distinct class of security vulnerabilities dubbed "Temporal Trust Gaps" (TTG) within the FFmpeg codebase. Unlike Anthropic’s Claude Mythos, which focused on identifying individual zero-day bugs through massive compute, Mythos SI analyzed the architectural patterns producing these flaws. The study revealed four vulnerabilities in FFmpeg’s MOV parser where valid state assumptions fail between validation and operation. This research demonstrates that a structure-focused approach can identify entire classes of vulnerabilities that agentic scaffolds might miss, even when operating at scale.
