What does the term "ransomware" refer to?

• A. A type of software that promotes advertisements
• B. A form of malware that encrypts files and demands ransom
• C. A tool to speed up computer performance
• D. A system for recovering lost data

Answer: (B)

Ransomware specifically refers to a type of malicious software that encrypts the files on a victim's computer or device, rendering them inaccessible. Once the files are encrypted, the attacker typically demands a ransom payment to provide the decryption key needed to regain access to the files. Ransomware attacks can significantly impact individuals and organizations, as they can lead to data loss, operational downtime, and financial costs related to the ransom itself, recovery efforts, or further security investments.

Understanding ransomware is crucial in the realm of cybersecurity, as it highlights the importance of preventive measures, such as regular data backups, using up-to-date security software, and educating users about phishing and other tactics used by cybercriminals to distribute ransomware.
