Types of Ransomware with Real-Life Scenarios
Compare locker ransomware, crypto ransomware, and double-extortion tactics.
Locker Ransomware
- Locker ransomware locks you out of your computer entirely but doesn’t encrypt files.
- Scenario: You turn on your computer, and instead of your desktop, you see a screen demanding payment to unlock it.
Crypto Ransomware
- This type encrypts your files, making them inaccessible without a decryption key.
- Scenario: Your important work documents and photos are replaced with encrypted files. The attacker demands payment for the decryption key.
Double Extortion Ransomware
- Attackers not only encrypt your files but also threaten to leak sensitive information if the ransom isn’t paid.
- Scenario: A hospital’s patient records are encrypted, and the attackers threaten to publish the data unless paid.
RaaS (Ransomware-as-a-Service)
- Cybercriminals provide ransomware tools to other attackers for a share of the profits.
- Scenario: A small business falls victim to a RaaS attack launched by an inexperienced attacker using a pre-made ransomware kit.
Key Takeaways
- Locker ransomware blocks device access.
- Crypto ransomware encrypts files.
- Double extortion adds data theft and public leak threats.
