Researchers have discovered a serious flaw in Apple's M-series chips. This security loophole, considered „unpatchable,“ could allow cyber intruders to steal encryption keys and sensitive data from his Mac computer.
The vulnerability is a side-channel exploit discovered by US academics that leverages the chip's execution of cryptographic protocols. Unlike typical flaws that can be fixed with a software update, this flaw is built into the chip's microarchitecture, posing a unique challenge for Apple.
Addressing this issue may require external encryption methods and may reduce performance on affected Macs, especially older models. M1 and M2.
It is labeled as “”go fetch” exploit has raised concerns among Mac users about password keychain security because it operates with normal user privileges. Some users have speculated that Apple will counter this threat through operating system enhancements, while others recall previous research suggesting this issue and that the upcoming M3 chips will include This suggests that it may contain functionality to thwart such vulnerabilities.
The revelations add further complexity as Apple pursues a major antitrust lawsuit with the Department of Justice. The Department of Justice has accused the tech giants of stifling competition and innovation through their App Store policies.
