Still interested in exploiting IPC memory corruptions on Apple devices? Try this one: CVE-2024-27801, UAF in the low level implementation of NSXPC that has been present since the initial release of NSXPC (over decade ago). POC: github.com/wangtielei/POC…

Was all set to share some PoC code, but then found that it still caused a kernel panic. Apparently, the issue hadn't been fixed as the vendor claimed. Sigh.

Web3 isn’t built from scratch—it builds on traditional systems. Its single point of failure remains an Achilles' heel. The Bybit incident isn’t the end, but just another example of ongoing attacks. A hard truth we can't ignore.

Got a codesigning requirement: anchor redacted and info[CFBundleIdentifier] = redacted* and certificate leaf[field.1.2.840.113635.100.6.1.9] /* exists */ or anchor apple generic and info[CFBundleIdentifier] = redacted* and certificate leaf[field.1.2.840.113635.100.6.1.27]

Just booked my trip to Vegas—wish me luck! Can’t believe it’s been 6 years since my last visit. Back then, I shared iPhone XS jailbreaks and FaceTime RCEs… wild how much has changed. If you’ll be around in Aug, don’t hesitate to say hi—let’s grab a drink or place a bet together!
