Four popular types of Ransomware use different techniques:

Lockers: Block access to all computer systems, use social engineering techniques to infiltrate computers. Usually, a pop-up appears on the screen with the ransom note and the instructions to follow for the payment.

Crypto: Can spread via emails, sites, and download infected files, encrypt all files on a computer, and block access even to entire servers. They are the most common Ransomware, and ransom requests always involve the release of a decryption key to get back all the stolen data.

Double Extortion: In this case, the threat consists not only in data encryption but also in the possibility that sensitive data is made public or sold on the Dark Web for other attacks. For this reason, even restoring from backups does not guarantee that the data will not be disseminated illegally.

RaaS: the acronym stands for Ransomware as a Service. It is a strategy that involves malware developers, who offer their services as a subscription to criminal organizations that would not have the technical skills to carry out such attacks.
