The NSA, CISA, FBI, DOE and EPA jointly warned on August 19 that attackers are using AI-generated exploitation scripts against internet-exposed Siemens S7 programmable logic controllers in US critical infrastructure, calling it an active threat rather than a theoretical one.
A poisoned Rust crate lived 86 minutes, and a fake installer lived on Anthropic's own domain News
The Rust package arrayref shipped a version on August 20 whose dependency ran a remote binary at build time, and it was removed roughly 86 minutes later, while a separate campaign used a genuine claude.ai shared-conversation page as the lure for Mac malware.
The executive order people keep reading as a license to hack back News
Executive Order 14390 directs federal agencies to pull commercial cybersecurity firms into disruption operations against foreign criminal networks, but it does not authorize private companies to attack anyone, and the Justice Department's computer-crime guidance is unchanged.
Anthropic still will not ship the model that found ten thousand vulnerabilities News
Anthropic says roughly 50 partners used its restricted Claude Mythos Preview model to find more than ten thousand high- or critical-severity software vulnerabilities, and the company still will not release Mythos-class models to the public because its safeguards are not good enough yet.
OpenAI hands its offensive cyber models to sixteen security firms News
OpenAI expanded its Daybreak Cyber Partner Program to sixteen named companies including Accenture, IBM, Cisco, CrowdStrike and Cloudflare, letting them embed its frontier cyber models in their own products while keeping model access away from end customers.
Z.ai changed only the post-training, and the model learned to find exploits News
Z.ai released GLM-5.3 on August 14 using the same base model as GLM-5.2, with every gain coming from post-training, and the largest jump was in finding and exploiting software vulnerabilities.
Forty-five agents with a shared forum found 266 bugs where solo agents found 21 News
