212-89 Malware Incidents Practice Question

You are using Wireshark to analyze traffic from an infected host. You notice consistent beaconing activity to an external IP on port 443. How do you isolate this traffic in your capture?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

ip.addr == [IP_ADDRESS]

The filter 'ip.addr == [IP_ADDRESS]' specifically isolates all packets associated with the destination IP suspected of being the C2 server.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ip.addr == [IP_ADDRESS]

    Why this is correct

    This filter restricts the display to traffic involving the specific IP.

  • tcp.port == 80

    Why it's wrong here

    This would only show HTTP traffic, not the specific beaconing traffic.

  • frame.len > 1000

    Why it's wrong here

    This isolates large packets, not specific C2 beaconing.

  • http.request

    Why it's wrong here

    This only shows HTTP requests, potentially missing encrypted beaconing.
