Cyber Range

Network Traffic Analysis

This cyber range allows you to learn and practice useful skills related to analyzing network traffic. You will work with Terminal Shark (TShark), Scapy and other tools to identify common network protocols, examine malware communications, extract transmitted files, filter output to display specific information, view communication statistics and much more. The labs in this range involve examining network capture files as well as capturing live traffic.

The labs

Train hands-on

  • Introduction to Terminal Shark

    Terminal Shark, or TShark, is the command-line version of Wireshark, which is a commonly-used tool for network traffic analysis. This lab is designed to provide an introduction to Terminal Shark, including some of the most common command flags and uses.

  • Extracting Files from Traffic Samples in TShark

    Traffic captures commonly include files that are of interest to incident responders. Emails may include embedded malicious files, or multi-stage malware may download additional malware to achieve certain purposes. Since some malware removes itself from the system after execution, extracting it from a network capture may be the only option to get a copy. This lab explores methods of extracting files from network traffic using Terminal Shark (or TShark).

  • Decrypting SSL and TLS in TShark

    Over half of all Internet traffic is now encrypted. Malware also makes heavy use of encryption to hide malicious content among legitimate traffic. In this lab, we will decrypt traffic encrypted with SSL and TLS using Terminal Shark (TShark).

  • TShark and Command Line

    Explore how Terminal Shark can be combined with Linux Terminal commands for network monitoring.

  • Decoding and Decrypting Network Traffic Data

    This lab demonstrates how to identify and reverse various encoding and encryption algorithms commonly used to obfuscate malware command and control traffic.

  • Identifying Abnormal Traffic

    Malware authors and other cybercriminals will often misuse legitimate protocols for command and control. This lab explores some of the ways that this can be accomplished.

  • Scapy for Network Traffic Analysis

    Scapy is a Python library for performing network traffic analysis. Using Scapy, it is possible to easily view, manipulate and write scripts using packet data.

  • Traffic Generation with Scapy

    The purpose of this lab is to explore the use of Scapy for building fake packets, which can be used for a variety of different purposes.

  • Leaked Credential Extraction

    Many commonly-used network protocols were not designed to be secure by default. Unless they are encrypted using SSL/TLS, they perform authentication in the clear, allowing user credentials to be intercepted. This lab demonstrates how these credentials can be identified and extracted.

  • Traffic Replay and Live Traffic Analysis in TShark

    This lab explores some of the options available when performing live traffic analysis with Terminal Shark (TShark).

  • Network Data Collection

    Learn how to use existing and custom honeyboxes and other tools to collect network traffic for further analysis.

  • Connection Analysis

    Understand connection analysis and what data can be extracted from high-level network traffic data.
