Ransomware, a variety of malware which encrypts user files and demands payment in return for a key, has become a major threat to businesses and the average user alike.
Coming in a variety of forms, ransomware most often compromises PCs through phishing campaigns and fraudulent emails. Once a PC is infected, the malware will encrypt, move, and potentially delete files, before throwing up a landing page demanding a ransom in Bitcoin.
Demands for payment can range from a few to thousands of dollars. However, giving in and paying the fee not only further funds the development and use of this malware, but there is no guarantee any decryption keys given in return will work.
