A recent study has raised alarms after identifying a vulnerability in Apple’s M-series chips that has the potential to enable hackers to retrieve the cryptographic private keys of Mac users.
In the absence of a direct resolution, the other method suggested by researchers may drastically hamper performance.
Apple M-Series Chips Susceptible to Key Extraction
The vulnerability in question functions as a side channel, thereby permitting the extraction of end-to-end keys when Apple chips execute implementations of commonly employed cryptographic protocols. Due to its origin in the microarchitectural structure of the silicon, direct patching is not feasible, unlike traditional vulnerabilities.
Instead, the report highlighted a fix that relies on integrating defenses into third-party cryptographic software. However, this approach may significantly, “degrade” the performance of M-series chips during cryptographic tasks, especially evident in earlier generations like M1 and M2.
