Using a Pixel with GrapheneOS that features Inactivity Reboot, MTE, and more? — You must be a drug dealer. 🚨

Using an iPhone 17, which now also ships with EMTE, Inactivity Reboot, SPTM, TXM, Conclaves, ...? — Oh, just the average Apple fangirl/boy who gets a new device every year due to camera improvements. ✅

GrapheneOS released some innovative mitigations prior to Apple. Yet, it needs Big Tech to apply such ideas and make phones more secure at scale.

Tarlogic found a "backdoor" in the ESP32 chips: https://social.lansky.name/@hn100/114127956134801350

Broadcom and Cypress chips have the same HCI "backdoor" allowing to write to the Bluetooth chip's RAM. This feature is used for firmware patches.

We didn't request CVEs for that 9 years ago. Instead, we built the InternalBlue Bluetooth research framework: https://github.com/seemoo-lab/internalblue

Want to learn iOS reverse engineering? Let's explore user space apps and daemons, discover and fix bugs with automated fuzzing, dive into low-level kernel and firmware internals, and forensically analyze backups and sysdiagnoses.

How does the new iOS inactivity reboot work? What does it protect from?

I reverse engineered the kernel extension and the secure enclave processor, where this feature is implemented.

See the latest iOS inactivity reboot in action! 🔒

iOS 18 comes with improved anti-theft measures. Three days w/o unlock, the iPhone will reboot, preventing thieves from getting your data.

Inactivity reboot puts your iPhone into "Before First Unlock" state, effectively locking encryption keys in the Secure Enclave Processor. Even if thieves leave your iPhone powered on for a long time, they won't be able to unlock it with cheaper, outdated forensic tooling. (1/2)
