The biggest Cyber Attack of all time : WannaCry Ransomware

A global cyber attack has been underway since last Friday, affecting more than 200,000 organisations in 150 countries. In India too, many organisations including Government Departments are facing the Ransomeware effect. In fact, RBI has told that white label ATM expansion stopped due to this cyber threat.

The “WannaCry” ransomware appears to have used a bug/weakness/flaw in Microsoft’s software, discovered by the National Security Agency and leaked by hackers, to spread rapidly across networks locking away files.
