NOTICE: Potentially malicious update is available in LT Patch Manager [Updated]
Posted on September 30, 2015
There is a Potentially malicious update available as a definition update and it shows up in the LT Patch Manager. If you’re using automatic patch approval, you’re clients are susceptible to having it installed.
I would strongly advise denying this patch for all of your agents to prevent any problems. The KB is KB3877432 and the title gives it away as a problem. Information is scarce, and there are more questions than answers right now, but it’s better to be safe and deny it than to risk having it installed.
Update:
Looks like the scare today was just a hiccup on Microsoft’s end. Yay, right?
Microsoft said a highly suspicious Windows update that was delivered to customers around the world was the result of a test that wasn’t correctly implemented.
