How Mac Apps Can Spy On Your Computer
Why You Should Be Worried
In a report published on February 10, Krause explains that pretty much any Mac app can take advantage of a developer feature in Apple’s macOS software to take screenshots of your computer whenever they want. There’s no sort of alert when an app takes a screenshot and it works even when the app is running quietly in the background.
Even worse, Krause discovered that he could combine those screenshots with Optical Character Recognition (OCR) software to automatically read any text included in them. That means hackers could potentially use the exploit to steal your account passwords, read your emails, or even spy on your banking information.
According to BleepingComputer, Krause reported the issue directly to Apple back in November 2017, but the company never released a patch.
