Red Team C2 Log Visualization



RedEye is a visual analytic tool supporting Red & Blue Team operations

RedEye is an open-source analytic tool developed by CISA and DOE’s Pacific Northwest National Laboratory to assist Red Teams with visualizing and reporting command and control activities. This tool, released in October 2022 on GitHub, allows an operator to assess and display complex data, evaluate mitigation strategies, and enable effective decision making in response to a Red Team assessment. The tool parses logs, such as those from Cobalt Strike, and presents the data in an easily digestible format. The users can then tag and add comments to activities displayed within the tool. The operators can use the RedEye’s presentation mode to present findings and workflow to stakeholders.

RedEye can assist an operator to efficiently:

  • Replay and demonstrate Red Team’s assessment activities as they occurred rather than manually pouring through thousands of lines of log text.
  • Display and evaluate complex assessment data to enable effective decision making.
  • Gain a clearer understanding of the attack path taken and the hosts compromised during a Red Team assessment or penetration test.

User Guide

Quick start

The fastest way to get up and running is by downloading the latest RedEye binaries for your operating system in the Releases section on GitHub.

RedEye currently supports uploading Cobalt Strike logs and offers both Red Team and Blue Team modes.

  • The Red Team mode offers the ability to upload campaign logs, explore, and create presentations. This mode is started by running RedEye with the SERVER_BLUE_TEAM=false environment variable or the --redTeam argument.
  • The Blue Team mode enables the ability to review a read-only campaign exported by a Red Team. This mode runs by default.

Note: Both Red and Blue Team modes can be started from the same RedEye application binary.

Blue Team

The Blue Team version can be run by double-clicking the RedEye application binary.

RedEye runs by default at and will automatically open your default browser.

If a campaigns folder is located in the same directory as the RedEye application, RedEye will attempt to import any .redeye campaign files within. Campaign files can be exported in the “Red Team” version.

To prepare a version for the Blue Team, follow these two steps:

  1. Copy the RedEye application binary to an empty folder.
  2. Create a campaigns folder in the same directory and place the .redeye campaign files you want to send inside.

Red Team

The Red Team version comes in two parts:

  • The RedEye application binary and
  • The parsers folder containing the cs-parser Cobalt Strike log parser binary.

There are two options to run RedEye:

  1. Run the downloaded binary: AUTHENTICATION_PASSWORD=<your_password> ./RedEye --redTeam.
  2. Clone this repository and either:
    1. Docker Compose:
      1. Update the environment variables in `docker-compose.yml`.
      2. Run: `docker-compose -f docker-compose.yml up -d redeye-core`.
    2. Install and run the project directly (covered in the Local Build section).

The application runs by default at
