Odaily News Academic researchers revealed in a paper published on Thursday that a newly discovered vulnerability in Apples M-series chips may lead to the leakage of wallet keys. The vulnerability is a side channel that allows end-to-end key extraction when an Apple chip runs a cryptographic wallet, but the vulnerability cannot be directly patched because it stems from the microarchitectural design of the chip itself. Instead, this issue can only be mitigated by building defenses into third-party encryption software, which significantly degrades M-Series performance when performing cryptographic operations, especially on earlier M1 and M2 generations. The vulnerability is exploited when the target cryptographic operation and a malicious application with normal user system privileges are running on the same CPU cluster. (Ars Technica)
