Which malware denies access to infected systems and demands a ransom to remove restrictions?

• A. Ransomware
• B. Privacy
• C. Recovery (Cold Site)
• D. Quad (SFP) or QSFP Transceiver

Answer: (A)

This question tests understanding of ransomware, a type of malware that denies access to infected systems or data and then demands payment to restore access. It achieves this by encrypting files or locking screens, rendering the victim unable to use their systems or information until the attacker’s decryption key is provided (typically for a ransom paid in cryptocurrency). The goal is financial gain through coercion, often with threats of permanent data loss or public disclosure if the demand isn’t met. The other terms don’t describe this behavior: privacy is not malware, recovery (cold site) is a disaster recovery concept involving standby facilities, and Quad/SFP transceivers are hardware components used for network connectivity rather than malicious software.
