Ransomware is a type of malware that encrypts a victim's files, making them inaccessible, and requires a ransom paid in order to decrypt the files. There are three common kinds of ransomware:
1. Locker ransomware: This type of ransomware prevents victims from accessing their gadgets by locking the screen or system, making it difficult to utilize the gadget until the ransom is paid.
2. Crypto ransomware: This kind of ransomware encrypted victims' files, making them inaccessible. In order to get the files back, victims must pay a ransom.
3. RaaS (Ransomware-as-a-Service): This type of ransomware allows anybody to create and disperse their own ransomware. The person who produces the ransomware will get a part of the ransom, while the individual who distributes the ransomware will get the rest.
Locker ransomware is the most common type of ransomware, followed by crypto ransomware. from this source RaaS is the least common type of ransomware.
