Ransomware is a form of malware that deliberately prevents access to files on a device by encrypting the files and demanding that a ransom be paid in order to have them decrypted.

There are several different kinds of ransomware:

– Crypto malware. This is the most common type of ransomware that encrypts files on the device in order to extort money.
– Lockers. This kind of ransomware infects operating systems to completely lock users out of their devices.
– Scareware. This is fake software that claims to have found issues on your computer and demands money to resolve the fake issue.
– Doxware. This type of malware threatens to publish your stolen information online if you don’t pay the ransom.
– Ransomware as a service (RaaS). This is where cybercriminals create ransomware and sell it to other people to use.
