Chrome is now shipping updates every 2 weeks as AI changes the security landscape

Google switches Chrome to two-week release cycles starting with Chrome 153, shrinking the N-day patch gap as AI-driven threats accelerate.

Chrome officially moved from a four-week to a two-week release schedule with Tuesday's launch of Chrome 153 on desktop, iOS, and Android. Google ties the change to its evolving security strategy, saying faster releases shrink the N-day patch gap as AI tools and community bug reports increase patch volume. Mozilla, Microsoft, and Brave have already adopted the two-week cadence, and Google is also racing AI-native browsers like Brave, Dia, Opera Neon, and Perplexity's Comet while experimenting with AI features in Chrome.

Most of the bugs Claude Mythos found have never been checked by a human

Echo's analysis found only 1,900 of 23,019 Claude Mythos-found vulnerabilities were externally reviewed, 90.8% held up, but the model overstated most severities.

Echo analyzed results from Anthropic's Claude Mythos Preview vulnerability sweep across 281 open-source projects, which produced 23,019 candidate vulnerabilities, of which only 1,900 were externally reviewed. Of those, 90.8% held up as real, 1,451 of 1,596 maintainer reports were acknowledged, 97 fixes landed upstream, and 88 became advisories, but 14 of the 27 CVE-assigned severity ratings mismatched independent scoring, mostly overstated. On Anthropic's SpiderMonkey benchmark, Claude Mythos turned known crashes into working code execution exploits in 72.4% of 250 trials, versus below 1% for Claude Opus 4.6. Echo cautions the reviewed sample likely was not randomly drawn, so the accuracy figure may not generalize to the other 21,119 unreviewed candidates.
