What is it?
Ransomware, as the name suggests, is a form of malware which locks away a victim’s files and then requests payment from them to have them returned.
In 2013, Cryptolocker attacked around 250,000 computers worldwide stealing personal files and refusing to return them unless a ransom was paid immediately, which a high amount of victims went ahead and did.
Ransoms are paid through a digital currency such as Bit coin, which allows transactions to be made anonymously.
