Network Navigator

Background

Security teams have detected suspicious network traffic originating from a corporate workstation. The traffic appears to be using a covert channel to exfiltrate sensitive data. Your task is to analyze the captured traffic and identify the method being used.

Objective

Using the provided packet capture:

1. Identify the protocol being used for data exfiltration
2. Find the destination of the exfiltrated data
3. Decode the hidden message in the traffic

Tools Recommended

• Wireshark
• NetworkMiner
• tshark

Analysis Steps

1. Examine the packet capture file
2. Look for unusual patterns in:
   • DNS queries
   • HTTP headers
   • Timing intervals
3. Decode any suspicious data
4. Document the exfiltration method

Notes

• All required data is contained within the packet capture
• Focus on anomalous traffic patterns
• Consider timing-based covert channels

Remember to document your analysis methodology and any tools used during the investigation.
