This Windows Update exploit is downright terrifying

Windows Update may occasionally backfire with faulty patches, but for the most part, it’s meant to keep us safe from the latest threats. Microsoft regularly pushes new patches that address potential vulnerabilities. But what if there were a tool that could undo every Windows Update and leave your PC exposed to all the threats Microsoft thought it had already fixed? Bad news: Such a tool now exists, and it’s called Windows Downdate.


Don’t worry, though. You’re safe from Windows Downdate — at least for now. The tool was developed as a proof-of-concept by SafeBreach researcher Alon Leviev, and although its potential is nothing short of terrifying, it was made in good faith as an example of something called “white-hat hacking,” where researchers try to find vulnerabilities before malicious threat actors can do it first.
