Wannacry, Cryptolocker, and more malicious software names have made headlines in the last couple years. Ransomware programs like these infect host systems and hold data hostage, trojan viruses that turn into extortion schemes. Maybe you pay them, and maybe the data gets returned or unlocked, or maybe it is permanently corrupted. Before you pay the ransom, call an expert. A lot of times they can be decrypted by someone who isn’t the hacker for less money, and with more trust.
