A critical security vulnerability has prompted a warning from the National Security Agency to Windows 10 users that they should make sure to update their PCs ASAP.
The flaw could potentially allow what is called ‘spoofing.’ Spoofing is when malicious software is able to change its digital signature to impersonate software coming from a legitimate source. This is much the same way that scammers can change how their phone number displays to trick you into thinking a call is coming from a legitimate source.
