On Friday computer networks of over 150 countries were targeted in a ransomware cyber attack called “WannaCry” that prevents access to data and systems. The attack is considered one of the biggest cybersecurity attacks in the recent history. The main victim, Britain’s healthcare system saw 48 of 248 NHS organizations disrupted by it, “the biggest ransomware attack ever.” The attack caused operations to be canceled and caused widespread disruptions in medical procedures. Many are getting notices to pay a ransom for a decryption key or risk having their files erased. A number of Chinese universities have also been under attack, leaving many unable to access their university theses.
