Hackers are using BlueKeep to break into Windows computers and install a cryptocurrency miner. The vulnerability only impacts systems that are running Windows 7, Windows Server 2008 R2, and Windows Server 2008.
If you’re running one of those three versions of Windows you should download and install a patch from Microsoft to correct the issue. The patches have been available since May, so there’s a good chance you’ve already updated.
That said, ZDNet reports that security researchers just spotted the first mass-hacking campaign using the exploit, so some Windows users didn’t get the memo.
When Microsoft issued a warning about the exploit in May it thought it would potentially be used as a self-spreading worm. Instead, hackers are using it to mine cryptocurrency, with some attacks dating back to October 23.
While the cryptocurrency mining is nowhere near as catastrophic a hack as could be done with the exploit, you should still make sure your computer has the patch installed so you’re not vulnerable going forward.
