Microsoft Boosts Ransomware Defenses for Windows 10

Citing the “elevated risk for destructive cyberattacks at this time,” Microsoft said yesterday it’s also making those updates available to customers with older versions of Windows no longer supported with regular patches.

Also known as WannaCrypt, the WannaCry ransomware attack hit computer systems around the world that are still using outdated software like Windows XP and Windows 7. Among the organizations affected were FedEx and the U.K.’s National Health Service (NHS).

Following the WannaCry attack, some researchers said North Korea was likely to blame, although officials in that country denied the allegation.

“Due to the elevated risk for destructive cyber attacks at this time, we made the decision to take this action because applying these updates provides further protection against potential attacks with characteristics similar to WannaCrypt,” Hall said in her blog post. However, the best defense against such malware is to update to a new platform that’s supported with regular security updates, she added.
