The last Chrome Browser CVE-2026-79236 Type Confusion in V8 exploited in less than < 24h by CyberKimi Told you, it will be exponentially difficult to catch up with CyberKimi when it comes to cyber ops, the RL rollouts are finally paying off. Now we autonomously exploited CVE-2026-79236 using CyberKimi, in less than 24h with our special Chrome exploit harness that chained 3 other bugs. I’m expecting this 24h buffer to shrink over RL rollouts. The full chain, no human wrote a line: → Our exploit harness patch-diff pipeline flags the V8 fix the day it ships → root-caused the homomorphic-IC wild write → chained 3 n-days: wild write → in-cage R/W → V8 sandbox escape → PC control (arm64 RegExp calling-convention bug) → PAC-safe JOP chain → system(), calc pops, V8CTF flag read, pure JS in the renderer. → target: Chromium 152.0.7977.60, M152 stable (Aug 25 2026), arm64 → reliability: 10/10 consecutive runs the exploit is of course not public, contact me contact@adverserial.ai if you want to know more and make sure to update your Chrome browser asap. I agree, the stuff that @DarioAmodei and @sama warned you about, is actually CyberKimi🐺 We are crafting exploit payload tokens on hard targets - join us, get into the waitlist: https://adverserial.ai/waitlist oh and CyberKimi is coming back very soon🐺 Chrome release: https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html
