RIP ๐Ÿชฆ Craziest bug I have ever seen in my 10 years of being in the iOS scene. I really wish Apple would stop being so anti consumer. Everyone who knew about this had an SRD suddenly overnight and nothing bad happened.
As others noted, Apple patched the not-so-secret server side bug. It enabled root access and jailbreaking even on iOS 27.2b3 (18 Pro Max). A public release would've meant an instant patch, so it stayed private. Despite efforts to preserve it, it's cooked. RIP ๐Ÿชฆ๐Ÿ˜ญ

Introducing the Frag Gap (CVE-2026-53362/CVE-2026-53366)! A bug in ipv4/ipv6 that I found together with @physicube, and it (used to) let you freely get root. This could affect Android too, but we don't have a device so... Full details are written up in both EN and KO at blog.qwerty.or.kr/en/posts/cโ€ฆ If you're curious about the code, just checking out github.com/qwerty-po/securitโ€ฆ is enough. We've got a few more fun bugs, and we'll post them as we find the time. This is just the Hitchhiker's Guide to the Linux Kernel. Don't Kernel Panic!

๐Ÿšจ Anthropic just showed a 27-minute workshop on how to actually do prompts for Claude. Taught by the people who built it. Free. No registration. No paywall. I've seen $300 courses that don't cover what they teach in the first 8 minutes. Watch it and bookmark it now.
