HE apple M1 chipApple’s laptops and desktops have a flaw that cannot be fixed with patches, as described by researchers at the Massachusetts Institute of Technology.MYTH), in the United States, Friday (10). The problem lies in a security mechanism called Beacon Authentication Codes (PAC).

This feature acts as a kind of last line of defense against potential intrusions, making it difficult to inject malicious code into device memory. However, the institution’s experts have developed an attack that can “guess” the exact authentication code to bypass the tool and invade the PC without a trace.

As proof of concept in the lab, “PAC MAN” even works against the software kernel of a device’s operating system (kernel). According to study co-author Joseph Ravichandran, such a finding has “great implications for future security work in all ARM systems with PACs.”

According to the report, security bug Affects the standard version and variants of the M1 processor M1 Professional and M1 Max. As for the newly announced Apple M2 chip, which also enables the beacon authentication mechanism, the existence of the flaw is not yet known as it has not been tested.

Apple minimizes risks

In the article, MIT researchers said most mobile devices and even desktops could be affected by lab-like attacks in the coming years if the problem is not mitigated. But for applethe vulnerability is not that serious besides relying on physical access to the device to be exploited.

“Based on our analysis and the details shared with us by the researchers, we conclude that this issue does not pose an immediate risk to our users and that the operating system alone is insufficient to circumvent its security protections,” Apple said. spokesperson Scott Radcliffe TechCrunch.
