What are different types of Ransomware?

Ransomware is a type of malware that encrypts a user’s files and demands a ransom, usually in the form of cryptocurrency, to decrypt them. There are several different types of ransomware, each varying in terms of how they operate and impact systems:

1. Encrypting ransomware: This type of ransomware encrypts files on the victim’s system, making them inaccessible until a ransom is paid. Examples include WannaCry and CryptoLocker.

2. Locker ransomware: This ransomware locks the victim out of their device entirely, preventing access until the ransom is paid. The files are not typically encrypted in this type.

3. Scareware: This type of ransomware tricks victims into believing their device is infected with malware, pushing them to pay for fake antivirus software to remove the threat.

4. Doxware: Also known as leakware or extortionware, this ransomware threatens to publish sensitive information unless the ransom is paid.

5. Mobile ransomware: Targets mobile devices like smartphones and tablets, exploiting vulnerabilities in mobile operating systems or applications.

These types of ransomware vary in their methods of attack, targets, and impacts. Some ransomware spreads through malicious email attachments or links, while others exploit vulnerabilities in software or networks. The impact of ransomware can range from temporary inconvenience to significant financial loss or data exposure. Victims are advised to avoid paying ransoms as it does not guarantee that files will be decrypted, and it funds criminal activities.
