CompTIA Security+ (SY0-501) — Question 873

A security analyst has identified malware that is propagating automatically to multiple systems on the network. Which of the following types of malware is MOST likely impacting the network?

Answer options

• A. Virus
• B. Worm
• C. Logic bomb
• D. Backdoor

Correct answer: B

Explanation

A worm is designed to replicate itself and spread across networks without human intervention, making it the most likely culprit in this scenario. In contrast, a virus requires user action to propagate, a logic bomb is triggered by specific conditions, and a backdoor provides unauthorized access but does not inherently spread like a worm.
