What is the main characteristic of ransomware?

The main characteristic of ransomware is that it locks a computer or the files on it until a payment is made. This type of malicious software encrypts the victim's data, making it inaccessible, and then demands a ransom payment in exchange for the decryption key. The threat of losing valuable data or permanent loss of access drives individuals or organizations to consider paying the ransom, although doing so does not guarantee that they will regain access to their data.

Other types of cyber threats, such as those that exploit network broadcasts, manipulate key presses, or provide remote control over devices, do not exhibit the primary behavior of ransomware, which centers around data encryption and payment demands. Ransomware's unique method of operation, specifically its focus on financial gain through intimidation and data loss, distinguishes it from other forms of malware.
