![]() ![]() Back in 2018, in a similar case, Meltdown and Spectre attacked vulnerabilities in Intel and ARM processors. According to researcher Daniel Moghimi “ Downfall attacks target a critical weakness found in billions of modern processors used in personal and cloud computers.” Intel released a patch, but it’s not the first time this has happened. Affected devices include Intel-powered Macs from 2015 onwards (M-series Macs are all ok). In August 2023 a serious vulnerability that affects Intel processors was highlighted. It’s not always a flaw in Apple’s software that can leave Macs vulnerable. More information here: Hacker ‘could take over any Apple webcam’. The vulnerability, which could enable a hacker to gain control of a Mac user’s camera, was identified by Ryan Pickren in July 2021 and fixed by Apple in macOS Monterey 12.0.1 on October 25, 2021. In 2021, Apple paid a student $100,000 after he discovered a dangerous vulnerability relating to Macs and reported it to Apple. ![]() Those pointing out vulnerabilities aren’t always ignored by Apple. Having had no response from Apple within 90 days he went public with details of the vulnerability. In another example, researcher Filippo Cavallarin found a Gatekeeper vulnerability in 2019 that he alerted Apple to. The developer had discovered the issue before the release of Ventura in October 2022, but a fix had not been issued, so, in August 2023, the developer went public with details of the flaw which meant that apps could bypass the check by App Management. Such vulnerabilities, though rare, could allow an attacker root access to your Mac.Īpple is usually quick to fix, but there have been cases where Apple has been criticized for being slow to respond to the threat once it’s been identified.įor example, in August 2023 a software developer released details about a flaw in App Management, a security feature introduced in macOS Ventura designed to prevent malicious software modifications and alerting the user in such an instance. ![]() When these are identified by security researchers (or friendly hackers) they usually alert Apple to them in the hope that the company will quickly close the vulnerability, quickly – or within zero days – before it is exploited. These vulnerabilities are sometimes referred to as back doors or as a zero-day vulnerability. However, from time to time security vulnerabilities are detected that could be used by hackers to exploit Macs. ![]()
