What is WannaCry Ransomware and how it is different from other cyber attacks

Jayant Saran, a forensic expert from Deloitte talks about the origin of the Wannacry ransomware and its worm-like capability.

The ransomware has become a global cyber-threat and India is as vulnerable as any affected country . The biggest problem with such ransomwares is that there is no well-known way to deal with it; even paying the ransom cannot guarantee that the files will be recovered.

As the name suggests, it's the blocking or encrypting of one's files and then being asked for a ransom to decrypt those locked files. A new ransomeware called 'Wannacry' or 'Wannacrypt' has attacked a few big countries and created havoc by targeting sensitive industries like healthcare.  

The biggest threat with 'Wannacry' is that it's more than just a ransomware; it can also be classified as a worm. Being a worm, the ransomware has the ability to spread to different systems running on the same LAN network or even spread through emails.
