Chrome CVE disclosures rose 563% by May in a surge VulnCheck partly credits to AI bug hunting

VulnCheck counted Chrome CVEs up 563% and GitHub-issued CVEs up 476% year to date in a May 14, 2026 post. It calls the rise consistent with AI-assisted bug finding, but whether the volume lasts is unknown, so exploitation data still sets patch order.

Bank of America still has 1,000 contractors patching flaws that AI models exposed

Bank of America CEO Brian Moynihan said 1,000 contractors hired in the second quarter to patch AI-exposed software flaws remain, on top of 3,000 staff. The headcount can anchor a budget; the dollar figure released with it cannot.

Nozomi Labs reports persistent abuse of weak credentials and exposed devices across OT and IoT

Nozomi Networks Labs reports persistent abuse of weak or default credentials and exposed industrial and IoT assets between June and August 2026. Faster exploit cycles and botnets that generate opportunistic traffic add volume on top, the vendor says.

Chainguard's Mythos harness finds a vLLM flaw that lets one client dictate another's output

Chainguard says its Mythos harness found a vLLM flaw, left in the public tracker for four months, that lets one client force another client's output. Versions before v0.31.0 are affected, and nothing is logged when the forced answer returns.

Anthropic's Cyber Mission targets the months between finding a bug and fixing it

Anthropic's Cyber Mission puts Claude models, engineers and funding behind bug fixing, after Glasswing finds often waited months for a patch. Its free OSS Scanner sends unreviewed reports that Anthropic expects to be over 90% accurate, so it suits maintainers who have time to verify them.

Anthropic sends unreviewed AI bug reports with proofs of concept to open source maintainers

Nethermind and ZEUS seek Anthropic AI bug reports that skip human review

Nethermind and ZEUS applied for Anthropic's OSS Scanner a day after it launched, asking for AI scans of Ethereum client and Bitcoin wallet code. Anthropic had manually checked about 6,000 of the 29,000-plus flaws its models flagged, crypto.news reported, so the teams that get the reports have to judge them.

Anthropic puts Opus 5.5, Sonnet 5.5 and Mythos 5.1 behind three tiers of cyber verification

Anthropic's Cyber Verification Program now gives security teams three tiers of access to Claude Opus 5.5, Sonnet 5.5 and Mythos 5.1 for defensive work. Getting in takes organization verification and control attestations, and a team learns its tier only from its own admin view.

Dimon puts a tenfold multiplier on AI cyber risk since Anthropic's Mythos

JPMorgan Chase CEO Jamie Dimon told Bloomberg TV that risks from AI went up 10-fold after Anthropic's Mythos model. The figure comes without a stated baseline, and the response on record is hundreds of staff working full time on JPMorgan's defenses since it got early access in April.

Anthropic will let verified organisations run "high risk offensive testing" with Claude Mythos 5.1 and its other top models, alongside the US government. Access goes to a select group, so whoever draws up the vetting list now decides which defenders can use the company's strongest cyber model.

Anthropic says a freely downloadable model builds exploits nearly as well as its restricted tool

Anthropic says Zhipu's freely downloadable GLM-5.3 built working V8 exploits in 50 of 410 tries, against 56 for its own restricted Claude Mythos Preview. With the weights public, its safeguards come off cheaply, so a lab that restricts its own model no longer keeps the capability out of reach.

Anthropic's Mythos model found a session-forgery path to RCE in Rejetto HFS 3.X

Horizon3 used Anthropic's Mythos model to find CVE-2026-61500, a chain that forges Rejetto HFS admin sessions and reaches remote code execution. The firm expects frontier models to make deeper, less reliable bug classes worth weaponizing at scale.

Palo Alto Networks pointed Anthropic's unreleased Mythos at its own systems and found 75 vulnerabilities in a month, against a usual rate below five. The defense business it built on that result depends on Anthropic's model and on customers choosing a security vendor over the lab.
