A large-scale cyber attack is confirmed on approximately 75,000 computer devices of around 100 countries on May 12, 2017. According to the media reports, the most probable reason is the security flaw found in Microsoft Windows OS, which allowed hackers to jump into the network.

Earlier it was reported that the attack was done at the institutional level only, but the hack gradually moved to many hospitals in England under National Health Service (NHS), FedEx and even Telefonica, a Spanish Telecom giant.

It is said that the hack is performed via WanaCrypt0r 2.0 - an encryption-based ransomware that encrypts the system files and keeps it unless money is paid to the source person. Though the creators of WanaCypt0r and WannaCry, a decryptor software are also surprised with the global reach on a massive scale.

Russia seems to be the most affected country followed by England, India, Ukraine.

Around 16 hospitals under NHS are hacked.
