CompTIA A+ Core 2 (220-1202) — Question 27

A customer is unable to open some files on their system. Each time the customer attempts to open a file, the customer receives a message that the file is encrypted. Which of the following best describes this issue?

Answer options

• A. Keylogger
• B. Ransomware
• C. Phishing
• D. Cryptominer

Correct answer: B

Explanation

The correct answer is B, as ransomware is a type of malware that encrypts files and demands payment for the decryption key. The other options do not pertain to file encryption; a keylogger records keystrokes, phishing attempts to steal credentials, and a cryptominer uses resources to mine cryptocurrency.
