Chinese LLMs can hack better than state-sponsored hackers with properly evolved harness - Kimi K2.5 managed to find and exploit 6 vulnerabilities in browsers: a single page view or an extension install by victims equal full system hijack. Check arxiv.org/abs/2604.20801

We've talked about #iOSTriangulation's stealth previously, however in our latest article, we look in detail at TriangleDB - the main implant. The level of stealth included using validators to ensure the exploits weren't delivered to security researchers. securelist.com/triangulation…
