Defensive Workshop: Initial Triage with TPVM

Let's walk through a simplified scenario for initial triage using Threat Pursuit VM. Imagine you receive an alert for suspicious outbound network traffic from a critical server.

  1. Launch Threat Pursuit VM: Boot the VM and ensure all network interfaces are configured correctly for analysis (e.g., bridged or host-only, depending on your setup).
  2. Capture Network Traffic: Use tools like Wireshark (pre-installed) to capture live traffic from the affected server or analyze a previously saved PCAP file.
  3. Analyze Traffic Patterns: Look for unusual protocols, destinations, data volumes, or connection frequencies. Tools like NetworkMiner can help dissect traffic into files and sessions.
  4. Identify Suspicious Connections: Utilize tools like `hping3` or `nmap` (used defensively here to understand port scanning behavior) within the VM to query the suspected destination IP and port.
  5. Malware Analysis (if applicable): If the traffic suggests a malware C2 channel, use the VM's malware analysis tools (e.g., Ghidra, IDA Free) on any identified suspicious executables or network payloads.
  6. Log Analysis: Correlate network events with system logs. Tools like Log2timeline/Plaso can aggregate timeline data from various sources on the compromised host, providing context.
  7. Documentation: Document all findings, including IPs, domains, timestamps, file hashes, and behavioral observations.

This initial triage is about quickly gathering enough information to determine if a full-blown incident response is necessary.
