Ransomware is a malicious program that locks a computer’s files until a ransom is paid. Ransomeware is not new in Cyber Crime but the size of this “Wanna Cry” malware is unprecedented

What are the techniques of ‘’WannaCry’’ Ransomware attack?
“ Wannacry” is a ransomware, an extremely heinous malware. Once it is activated on a computer or any Smart device it encrypts the files on that machine so they become inaccessible. There is also a code to delete files in the virus/malware. Unlike many other malicious programs/malware, this one has the ability to move around a network by itself.
Once “WannaCry” is inside an organization, it will hunt down vulnerable machines and infect them too. This is why the impact is so much –because large numbers of machines at each victim’s organization are being affected thereafter, it instructs the owner to pay a ransom to have their files unlocked.
The Ransom amount is between $300 to $600. Payment will be accepted in Bitcoin virtual currency only.
