Which type of malware is specifically designed to hold someone's data hostage?

• A. Spyware
• B. Trojans
• C. Ransomware
• D. Adware

Answer: (C)

Ransomware is a type of malware explicitly created to hold someone's data hostage. It typically encrypts the victim's data and demands a ransom payment to restore access to that data. The attackers leverage this threat to coerce victims, often presenting an ultimatum wherein files remain inaccessible until the ransom is paid. Ransomware can spread through phishing emails, malicious downloads, or vulnerabilities in software.

In contrast, spyware is designed to stealthily gather information from a user's device without their knowledge, while Trojans disguise themselves as legitimate software to trick users into installing them, usually resulting in harmful effects like data theft or system compromise. Adware typically serves unsolicited advertisements, often cluttering the user experience but does not inherently hold data hostage. Thus, ransomware is distinct in its malicious intent to leverage data access for financial gain.
