📋 BRIEFING
⚠ CLASSIFIED — NETWORK INTERCEPT OP

MISSION BRIEFING

Module 2  |  HTTP Credential Interception
Scenario
You have been given access to a packet capture tool on a compromised network segment. Another user on the network has recently authenticated to an internal web portal over unencrypted HTTP.

Because HTTP transmits data in plaintext, their credentials were sent across the network without any protection — and your sniffer was listening. Your task is to extract those credentials and use them to perform an account takeover.
Objectives
1
Use PacketScope Pro to capture and analyse network traffic. Identify the HTTP login request.
2
Follow the TCP stream to read the plaintext POST body and extract the credentials.
3
Use the extracted credentials to log in to the target web portal.
4
Navigate to Account Settings and change the user's password to complete the takeover.

Key Concept
HTTP sends all data — including passwords — as readable text over the network. Any device on the same network segment can intercept and read it. This is why HTTPS exists.
