Understanding the Difference Between Locker Ransomware and Crypto Ransomware

Introduction

In today's digital age, the threat of ransomware looms over businesses and individuals alike. Ransomware is a malicious software that encrypts or locks a victim's data and demands a ransom in exchange for its release. However, not all ransomware is created equal. There are two primary categories of ransomware: Locker Ransomware and Crypto Ransomware. In this blog post, we will explore the differences between these two types of ransomware and how to protect yourself from them.

Locker Ransomware: Locking You Out

Locker ransomware, also known as "screen locker" or "blocking ransomware," operates by locking the victim out of their system or device. It does not encrypt the victim's files but rather restricts access to the entire system or specific applications, rendering the device unusable. Once infected, the victim is presented with a screen or pop-up message, often masquerading as an official government agency or law enforcement, which accuses the victim of illegal activities and demands a ransom to unlock the device.

The primary characteristics of Locker Ransomware are as follows:

• Locks Access: Locker ransomware denies access to your system or specific applications, preventing you from using your device.

• No File Encryption: It doesn't encrypt or manipulate your files, which means your data remains intact.

• Social Engineering: Attackers often use social engineering tactics to scare victims into paying the ransom, by pretending to be law enforcement agencies or government entities.

• Payment Request: Like crypto ransomware, it demands a ransom, usually in cryptocurrency, in exchange for the unlocking code or access to your system.

• Removal: Locker ransomware is relatively easier to remove compared to crypto ransomware, as it doesn't involve file encryption.

Crypto Ransomware: Encrypting Your Data

Crypto ransomware, on the other hand, is a more insidious form of ransomware that encrypts the victim's files, making them inaccessible until a ransom is paid. This type of ransomware has gained notoriety for causing significant data loss and financial harm to businesses and individuals.

Here are the key features of Crypto Ransomware:

• File Encryption: Crypto ransomware uses strong encryption algorithms to lock your files, making them unreadable without the decryption key.

• No System Lock: Unlike Locker Ransomware, your system remains accessible. However, your files are encrypted and inaccessible.

• Payment Demand: Attackers demand a ransom in cryptocurrency, typically Bitcoin, in exchange for the decryption key.

• Data Loss Risk: Victims face a higher risk of data loss if they don't have backups or if they refuse to pay the ransom.

• Sophistication: Crypto ransomware is often more sophisticated and challenging to remove than Locker Ransomware.

Other (Scareware/Doxware)

• Scareware or Fake Antivirus Ransomware: Scareware doesn't actually encrypt or lock your files, but it displays intimidating pop-up messages, often claiming that your computer is infected with malware. It then demands a ransom to remove the supposed threats. These are usually not as destructive as other types of ransomware but are still fraudulent and malicious.

• Doxware (Leakware or Extortionware): Instead of encrypting files, doxware threatens to release sensitive information or documents unless a ransom is paid. The threat typically includes personal or confidential data. The threat actors may leak the data on the internet or use it for blackmail.

Conclusion

In conclusion, understanding the difference between Locker Ransomware and Crypto Ransomware is essential for effective protection against these threats. While Locker Ransomware locks you out of your system, Crypto Ransomware encrypts your files, potentially causing data loss. A combination of security measures, regular backups, and user education can significantly reduce the risks associated with both types of ransomware.
