Pointer Authentication Code News Today

Security researchers at Kaspersky have recently revealed a highly advanced iMessage vulnerability, dubbing it "Operation Triangulation."

Control-flow integrity (CFI) refers to techniques which prevent control-flow hijacking attacks. This article describes some compiler/hardware features with a focus on llvm-project implementations. CFI

Apples flashy M1 chip has an unfixable security flaw.

Apple M1: the chip suffers from a security flaw that cannot be corrected. Apple M1 chip has a security weakness that can't be fixed.

The MIT team found that M1's authentication code was vulnerable to hacking. Apple introduced the MacBook M1 series several years ago, and the M2 series is now available.

MIT researchers demonstrated multiple PoC attacks for a novel hardware attack method, dubbed PACMAN, that targets Apple's M1 processor chipsets.

MIT scientists found a new hardware vulnerability in the Apple M1 chip. They created a novel PACMAN attack methodology to show that Pointer Authentication Code - the last line of defense against typical software vulnerabilities - can be defeated without leaving a trace.

Researchers say they have discovered an unpatchable vulnerability affecting Apples custom Arm-based M1 silicon at the chips last level of defense.

The proof-of-concept attack from MIT CSAIL researchers undermines the pointer authentication feature used to defend the Apple chip's OS kernel.

Security researchers have analyzed a now-patched malware attack that was used to compromise Mac devices belonging to Hong Kong pro-democracy activists in November.
