A macOS 0-day vulnerability let hackers take screenshots

A macOS 0-day vulnerability lets hackers take screenshots of your screen. Hackers have been exploiting a vulnerability in fully updated versions of macOS that allowed them to take screenshots on infected Macs without having to get permissions from any users. However, this attack is finally getting patched with the latest macOS 11.4 update released on May 24th, 2021. If you haven’t already, update your machine today.


The zero-day was exploited by XCSSET, the malware was discovered by security firm Trend Micro. XCSSET used what at the time were two zero-days aimed at developers, specifically their Xcode projects, which then got passed on to regular users.


No one really knows how many Macs are infected, but in a statement from TechCrunch, Apple confirmed that the exploit is no longer an issue after updating to the latest version, the macOS Big Sur 11.4 update.
