WannaCry malware is a scary type of Trojan virus called “ransomware.” As the name suggests, the virus in effect holds the infected computer hostage and demands that the victim pay a ransom in order to regain access to the files on his or her computer. [Reference]
WannaCry encrypts most or all of the files on the computer and asks to pay certain fixed amount of money, as opposed to decrypting files or allowing access again to the operating system.
The software asks to pay ransom of $300 at the time of infection for first time. If the use doesn’t pay the ransom within 3 days, the ransom amount is doubled to $600. Are worst part is if user does not pay within seven days, WannaCry will delete all those encrypted files and all data will be lost for forever.
Two big telecom companies, Telefónica (TEF) of Spain and Megafon of Russia, were also hit, as was Japanese carmaker Nissan (NSANF) in the U.K. [Reference]
