Correct Answer:
Option C —
Encrypting files and demanding payment for decryption
Ransomware is a specific type of malicious software (malware) designed to block access to a computer system or its data. It typically does this by encrypting the victim's files, making them unreadable. The attackers then demand a "ransom" payment (often in cryptocurrency like Bitcoin) in exchange for the decryption key needed to restore the data.
• Option A: While some ransomware also threatens to leak data (double extortion), the primary historical purpose is the ransom for decryption.
• Option B: This is usually a side effect of viruses or "bloatware," not the primary goal.
• Option D: Deleting files is the behavior of "wiper" malware, which aims to destroy data rather than profit from it.
