Ransomware is a type of malicious software that encrypts files on a computer or server and requires the victim to pay a ransom to decrypt them. This type of malware has become one of the most common and dangerous types in the cybersecurity industry, causing serious damage to both individuals and organizations.
How does ransomware work?
Typically, ransomware enters the victim's computer through a malicious link, email, or through a security vulnerability. Once malware infects a device, it encrypts the files on the drive and blocks access to them. The ransomware then issues a ransom note, usually in the form of a message on a computer screen or as a text file in a folder with encrypted files.
Ransomware victims are often faced with ultimatums indicating that files will be permanently deleted if the ransom is not paid within a certain timeframe. In some cases, hackers may publish or sell sensitive data they obtained during the encryption process.
Types of ransomware
There are several types of ransomware, each of which works differently. Some of the most common types include the following:
Encrypting Ransomware - This type of Ransomware encrypts files on a computer, forcing the user to pay a ransom to get the keys to decrypt them.
Locker Ransomware - This type of ransomware blocks users from accessing their devices, and usually requires a ransom to unlock it.
Scareware Ransomware - This type of ransomware gives fake warnings on the screen, convincing the victim that their computer is infected with a virus and that they need to pay money to remove it.
Doxware Ransomware - This type of Ransomware threatens to release the victim's sensitive data unless they pay a ransom.
