What is Ransomware?

Ransomware is a new form of attack. Typically, criminals manage to gain remote access to a device. Once they can control the computer, they then lock it and hold it for ransom. They then demand that you pay them to regain access to your computer.

Ransomware attacks succeed because the attackers usually choose their targets very carefully. For example, the attackers may go for the typical corporate types. Once they gain access to a computer that you use for critical tasks, they know that you will not afford to lose all your data. Therefore, you are likely to comply with their demands when you use your computer for very important tasks.
