Gate News message, April 23 — Microsoft is integrating Anthropic’s Claude Mythos Preview AI model into its Security Development Lifecycle to identify software flaws earlier and accelerate remediation. The company’s testing on open-source benchmarks showed Mythos outperformed earlier models in vulnerability detection.
Anthropic reported that Mythos has discovered thousands of vulnerabilities across operating systems, web browsers, and other software. In testing, the model identified a 27-year-old bug in OpenBSD with a run cost under $50; across 1,000 testing runs, total expenditure remained below $20,000. Mythos Preview became the first model to complete the UK AI Security Institute’s 32-step corporate network attack simulation, succeeding in 3 of 10 attempts. The model can also convert known CVE identifiers into working exploits in under a day for under $2,000 in some cases.
The preview version will initially be available to a limited group of companies under a controlled security program that includes Microsoft, Amazon, and Apple. Anthropic cautioned that similar capabilities could spread widely, though fewer than 1% of vulnerabilities it has found have been patched to date.

OpenAI Codex Team Fixes OpenClaw Authentication Bug, Significantly Improves Agent Behavior
OpenClaw switches from Pi to Codex harness to fix a silent authentication fallback, with two PRs addressing the bridge and fallback; post-fix, the agent shifts from shallow heartbeat polling to a full work loop, enabling progress.
Abstract: OpenClaw’s Codex harness optimization addressed a critical authentication flaw that caused silent fallback to the Pi harness when using Codex with OpenAI models. Two pull requests fix the authentication bridge and prevent silent fallback, changing the runtime adapter. As a result, agent behavior evolves from shallow heartbeat polling to a full work loop that reads context, analyzes tasks, edits repositories, and verifies progress, improving continuity and visibility across heartbeats.

Anthropic weapon-grade cybersecurity model Mythos was accessed without authorization: how did they do it?
Bloomberg reported that a private forum group gained unauthorized access to Mythos through legally authorized use by a third-party contractor of Anthropic. Mythos is an enterprise-grade, defensive AI that is only available to large organizations that undergo rigorous review. The group used knowledge of the model URL to guess the system’s location to gain entry, and provided screenshot demonstrations, claiming it was still being used with no malicious intent. Anthropic is investigating and has preliminarily determined it was abuse of permissions rather than external intrusion. This case highlights the risk of entrusting highly sensitive models to third-party oversight, and underscores the need to strengthen governance resilience and trust mechanisms.
