CompTIA Network+ (N10-008) — Question 809

Which of the following compromises Internet-connected devices and makes them vulnerable to becoming part of a botnet? (Choose two.)

Answer options

• A. Deauthentication attack
• B. Malware infection
• C. IP spoofing
• D. Firmware corruption
• E. Use of default credentials
• F. Dictionary attack

Correct answer: B, E

Explanation

Malware infection (B) directly compromises devices by installing malicious software that allows control by a botnet operator. Use of default credentials (E) makes devices easily accessible to attackers, who can then incorporate them into a botnet. The other options, while security concerns, do not specifically lead to devices becoming part of a botnet in the same manner.
