Cryptoworms are the latest type of semi-autonomous and self-propagating ransomware. Like a normal computer worm, a cryptoworm does not need any input from a human to replicate and infect devices.
The aim of cryptoworms is like that of any other ransomware. Cryptoworms want to infect a given device and encrypt all its data, then demand money from the device’s owner to return the data. Cryptoworms spread via methods such as spam email and malicious links on compromised websites.
