Anthropic is positioning its gated Claude Mythos Preview model as offering a "striking leap" in many evaluation benchmarks over its predecessor, which at the time of launch was Opus 4.6.
yes, as in singular one. Back in April 2026 Anthropic caused a lot of media noise when they concluded that their new AI model Mythos is dangerously good at finding security flaws in source code. Apparently Mythos was so good at this that Anthropic would not release this model to the public yet but instead … Continue reading Mythos finds a curl vulnerability →
Anthropic is positioning its gated Claude Mythos Preview model as offering a "striking leap" in many evaluation benchmarks over its predecessor, which at the time of launch was Opus 4.6.
Anthropic's Mythos showed that given enough inference, all bugs are shallow. But who pays for the inference? We benchmarked Claude Opus 4.6 against Corgea v1 and v2 to show why purpose-built scanner architecture beats raw model capability on precision, recall, cost, and speed.
A name identifies what object we want to access; an address identifies where the object is located. But there are subtleties to naming
AI did not invent new attacks. It billed the old ones monthly. Crypto is the only place we can count it, and the early signals are in.
GitHub and industry leaders warn of a massive surge in unvalidated AI vulnerability reporting, forcing bug bounty programs to tighten rules against the noise.
Google has patched an Android ADB bug in the May security patch set. If you have a Pixel phone you should already have the patches, and most other major manufacturers should be close behind. Unfort…

cURL creator Daniel Stenberg says Anthropic's hyped Mythos bug-hunting model found only one confirmed low-severity vulnerability in cURL, plus a few non-security bugs, after he expected a much longer list. He argues Mythos may be useful, but not meaningfully beyond other modern AI code-analysis tool...
The tech giant says this is the first time it has identified such a case.
Something (slightly) less boring than nothing.
Daniel Stenberg has published a lengthy article on his thoughts on Anthropic's Mythos, which th [...]
Yesterday, I wrote about the massive increase in security issues being identified by AI. Daniel Stenberg, the author of curl, was a key part of that story. At first he was being overwhelmed by a torrent of “AI slop” reports. In the last few months, the reports have become almost all legitimate, but the pace hasn’t changed. Today, Stenberg posted about his recent experience with Claude Mythos.
