5 Types Of Ransomware You Should Know About

by | Jan 2, 2022 | Cybersecurity Blog

Ransomware is considered one of the most dangerous types of malware that can enter a person’s computer through unknowingly clicked links, attachments in emails, or compromised content published on infected websites.

Ransomware restricts access to a computer system or data until a ransom is paid. The ransomware encrypts files using public-key cryptography with an encryption key that is randomly generated for each file.

These types of ransomware typically use strong encryption algorithms and are virtually impossible to crack. The latest strain of cybercriminals asks users to pay a ransom in cryptocurrency, so there is no way of telling if the hackers will even deliver the decryption keys.

Types Of Ransomware

#1 Encrypting Ransomware

Form of malicious software designed to block access to a computer system through encrypting certain types of data and demanding a ransom for its decryption keys.     

This sort of ransomware is particularly hazardous since once thieves have access to your files, no amount of protection software or system restore will be able to restore them to you. Even if you pay, there’s no guarantee that the thieves will return your files.

#2 Screen Lockers 

Type of ransomware that prevents computer owners from accessing their devices. When lock-screen ransomware infects your computer, you will be locked out completely. 

A full-size window will show when you turn on your computer, typically accompanied by a message stating that criminal behavior has been detected on your computer and you must pay a fee.

#3 Scareware 

 Fake anti-virus software that tricks users into thinking their computers are badly infected with malware to get them to buy the non-existent protection.  

When installed, scareware programs display fake security alerts, virus definitions, or scan results that indicate numerous infections present on the system. A pop-up message may appear, suggesting that malware has been identified and that the only way to remove it is to pay money.

#4 Mobile Ransomware  

Mobile ransomware typically displays a message that the device has been locked due to illegal activity. The message states that the phone will be unlocked after paying a fee. 

Mobile ransomware is often delivered via malicious apps and requires that you boot the phone up in a safe mode and delete the infected app to retrieve access to your mobile device

#5 Mac Ransomware  

Ransomware targeting Apple computers. In March 2016, a ransomware program known as KeRanger was the first functioning ransomware seen on the mac IOS platform; it encrypted data and demanded 1 bitcoin (about 450 U.S . dollars) to decrypt the files.

Fortunately, Apple’s built-in anti-malware application, XProtect, published an update shortly after the ransomware was identified, preventing it from infecting user PCs. However, Mac ransomware is no longer a hypothetical threat.
