Anthropic’s new AI model finds and exploits zero-days across every major OS and browser

Automated vulnerability discovery tools have existed for decades, and the gap between finding a bug and building a working exploit has always slowed attackers. That gap is now substantially narrower. Anthropic’s Claude Mythos Preview, a new general-purpose language model being made available only to a limited group of critical industry partners and open source developers, can autonomously identify zero-day vulnerabilities and then construct working exploits across every major operating system and major web browser.

Cloudflare moves up its post-quantum deadline as researchers narrow the path to Q-Day

Cloudflare announced it is targeting 2029 to complete post-quantum security across its entire product suite, including post-quantum authentication. The company is following a revised roadmap that Google also adopted after announcing that it had improved the quantum algorithm used to break elliptic curve cryptography. Google stopped short of publishing the algorithm, disclosing only a zero-knowledge proof of its existence. The same day, a company called Oratomic published a resource estimate for breaking RSA-2048 and P-256 … More → The post Cloudflare moves up its post-quantum deadline as researchers narrow the path to Q-Day appeared first on Help Net Security.

AI-enabled device code phishing campaign exploits OAuth flow for account takeover

A phishing campaign that bypasses the standard 15-minute expiration window through automation and dynamic code generation, leveraging the OAuth Device Code Authentication flow to compromise organizational accounts at scale, has been observed by the Microsoft Defender Security Research team. The campaign uses AI-assisted infrastructure and end-to-end automation. Attack overview Device Code Authentication is a legitimate OAuth flow designed for devices that cannot support a standard interactive login. In this model, a code is presented on … More → The post AI-enabled device code phishing campaign exploits OAuth flow for account takeover appeared first on Help Net Security.

GitHub Copilot CLI gets a second-opinion feature built on cross-model review

Coding agents make decisions in sequence: a plan is drafted, implemented, then tested. Any error introduced early compounds as subsequent steps build on the same flawed assumption. Self-reflection is a recognized mitigation technique, and one GitHub Copilot already supports, but a model reviewing its own output is still constrained by the same training data and blind spots that produced it. GitHub addressed that constraint this week with the release of Rubber Duck, a cross-model review … More → The post GitHub Copilot CLI gets a second-opinion feature built on cross-model review appeared first on Help Net Security.
