Microsoft issues WannaCry security patch for XP, blasts US for ‘stockpiling vulnerabilities’

The WannaCry ransomware attack infected over 200,000 computers in 150 countries, including the UK’s National Health Service, and experts expect more victims as hackers create new variants. Microsoft released a security update for outdated Windows systems, but warned that users who have not applied the update are at risk. Microsoft also criticized governments for stockpiling vulnerabilities, which have leaked and caused damage.
