On 12th May 2017, the Microsoft Windows software operating systems has hit by a dangerous virus called ‘WannaCry ransomware’ which almost spread into the 150 countries and infected more than the 230,000+ computers. Anti-virus companies claim that this is the biggest ever cyber-attack in the history which will spread into your desktops through the phishing emails, unpatched Windows systems.
WannaCry ransomware mainly attacked Telefonica, FedEx, LATAM Airlines, Deutsche Bahn and UK’s national health services. Mostly the Health services are hit by the ransomware such as calling back emergency ambulances, stalling surgeries and deleting the patient’s medical data.

Sources also claim that North Korea has a hand in WannaCry ransomware attack because one of the computer researchers recently found that virus contains hidden clue codes which link to the North Korea.

Computer emergency response team (CERT) advised that WannaCry ransomware has to spread through the phishing emails from unknown sources and with the illegal OS patch Softwares.
So in order to stay safe from the ransomware attack user should respond to the anonymous emails from the various sources and in case if a user responded to emails should immediately disconnect the infected computer from the local network because it spreads through LAN connections.
Most of the computers in India were also attacked by WannaCry ransomware and the count of affected systems has been increasing day by day. Especially we Indians love to download pirated softwares and movies from the illegal sites.
This enables the hackers around the world to know how their bug is performing by testing it in countries like India. So we’re opening doors for hackers to test their virus programs on our computers, to stop this we should use official premium software’s, and we should not download any content from the unknown sources on the internet.
