0Sofia responds to the desk of a user who reports slow system activity. Upon checking outbound network connections from that system, Sofia notices a large amount of social media traffic originating from the system. The user does not use social media, and when Sofia checks the accounts in question, she sees they contain strange messages that appear encrypted. What is the most likely cause of this traffic?
Answer Options
A
Other users are relaying social media requests through the user's computer.
B
The user's computer is part of a botnet.
C
The user is lying about her use of social media.
D
Someone else is using the user's computer when she is not present.
Correct Answer: B
Explanation
Social media is commonly used as a command-and-control system for botnet activity. The most likely scenario here is that the user's computer was infected with malware and joined to a botnet. This accounts for both the unusual social media traffic and the slow system activity.
