CompTIA Security+ (SY0-501) — Question 1023

A security analyst is investigating a security breach. Upon inspection of the audit an access logs, the analyst notices the host was accessed and the /etc/passwd file was modified with a new entry for username `gotcha` and user ID of 0. Which of the following are the MOST likely attack vector and tool the analyst should use to determine if the attack is still ongoing? (Select TWO)

Answer options

• A. Logic bomb
• B. Backdoor
• C. Keylogger
• D. Netstat
• E. Tracert
• F. Ping

Correct answer: B, D

Explanation

The correct answer includes 'Backdoor' because it indicates unauthorized access, which is likely involved in the attack. 'Netstat' is also correct as it can be used to check active connections and determine if the backdoor is still being exploited. The other options do not directly relate to assessing ongoing attacks or monitoring network connections.
