Microsoft rushes out Windows fix after trusted security keys were found at risk
Microsoft has issued an emergency Windows update after discovering a problem with digital certificates from eMudhra that could let criminals make harmful files or websites appear trustworthy. The update removes affected certificates so Windows can better block this kind of abuse.
Who is at risk
Windows users and organizations that rely on trusted downloads, websites, or signed software are most at risk if their devices have not installed the latest updates.
What to watch for
Watch for unusual security warnings, unexpected prompts to install software, or files and websites that seem legitimate but behave strangely.
What to do
Install the latest Windows updates immediately on all devices and restart if prompted to make sure the emergency protection is applied.
