What is ransomware?

Ransomware is a specific category of malware designed to deny access to a victim’s files or system, typically by encrypting the victim's data. The attacker then demands payment, often in cryptocurrency, in exchange for the decryption key that would allow the victim to regain access to their data. This form of cyber extortion is particularly malicious as it targets critical data and can severely disrupt personal and organizational operations. The primary objective of ransomware is financial gain, exploiting the victim's desperation to recover their data. Understanding this definition of ransomware is crucial in recognizing its impact on cybersecurity and the importance of preventative measures.
