Mechanical keys were never secure. But RFID electronic key is not secure either. Cars should not have a physical key at all. All modern cars should only have a cryptographically secure keyfob backed by Distance Bounding Protocol and a monotonic clock inside.

Secure boot bypass on Samsung Galaxy A series. Secure boot chain is executed before Android Verified Boot verifies vbmeta. You can achieve root and can also flash custom images without unlocking the bootloader and it will still pass Play Integrity hardware backed attestation.

Plans to literally "hack the planet" foiled due to 500ms of latency that Andres instinctually investigated. The latency was due how the malicious code parsed symbol tables in memory. openwall.com/lists/oss-secu…

@co_apprentice @warraagal Measured boot already exist in Android, in uh 14-launched SoC? But it doesn't allow using it for encryption, it's here only to enforce Google monopoly, just a more secure key attestation. Using it to derive an encryption key isn't done by google and they have no plan for it \
