RedEye: Red Team C2 Log Visualization

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 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.

⚠️ This Repo Currently in Maintenance Mode ⚠️

This GitHub repository is no longer under active development. We'll review community issues and pull requests for bug fixes, but won't consider any new feature additions.

Quick start

1. Download the latest RedEye binaries for your OS* from the Releases page.
2. Pick a mode and Run the server
   • Red Team mode enables the full feature set: upload C2 logs, explore data, and create presentations. You must provide a password to run in Red Team mode. To start the server in Red Team mode, run the following in a terminal.

     ./RedEye --redTeam --password <your_password>
     

   • Blue Team mode (default) enables a simplified, read-only UI for reviewing campaigns exported by a Red Team. To start the server in Blue Team mode, run the following in a terminal.

     ./RedEye   # Or simplify double-click the "RedEye" executable 
     

3. Use the web app in a browser at http://127.0.0.1:4000. The RedEye binary runs as a server in a terminal window and will automatically open the web app UI your default browser. You must close the terminal window to quit the RedEye server.
4. Try importing the gt.redeye example dataset to get started. Or try a different example dataset.

MacOS Issue - When running RedEye for the first time, you may get a "not verified" error. You must go to "System Preferences" > "Security & Privacy" > "General" and click "Open Anyway." More info on the Apple support page.

Follow the User Guide to learn about RedEye's feature set.

Red Team & Blue Team Modes

RedEye has two modes that cover two stages of the Red Teaming process. Red Team mode allows importing C2 data, editing imported data, and making comments and presentations. After curating and annotating campaign data, Red Teams can export their campaign as a standalone .redeye file and hand it off to a Blue Team for reporting and remediation. Blue Team mode runs RedEye in a simplified read-only mode for viewing curated data exported by a Red Team.

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

Red Team

The downloaded binary comes in two parts:

• The RedEye application binary
• The parsers folder containing parser binaries (e.g. cobalt-strike-parser Cobalt Strike log parser binary)

There are three options to run RedEye in Red Team mode:

1. Run the downloaded binary, passing in the --redTeam and password options:

   ./RedEye --redTeam --password <your_password>
   

2. Clone, install, and run the project directly (covered in the Local Build section).
3. Docker Compose
   1. Clone the repo
   2. Update the environment variables in docker-compose.yml.
   3. Run:

      docker-compose -f docker-compose.yml up -d redeye-core
      

Blue Team

The Blue Team mode is a simplified, read-only UI for displaying data that has been curated, annotated, and exported by a Red Team. This mode runs by default to make startup more simple for the Blue Team.

The Blue Team version can be run by double-clicking the 'RedEye' application binary. RedEye runs at http://127.0.0.1:4000 (by default) and will automatically open your default browser.

Blue Team Presentation Handoff

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 mode.

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.

Folder/
	RedEye
	campaigns/
		Campaign-01.redeye
		Campaign-02.redeye

.redeye files can also be uploaded in Blue Team mode via the "+ Add Campaign" dialog.

Example Datasets

There are example datasets in this repo available for download. These are located in the ./applications/redeye-e2e/src/fixtures folder.

• gtdataset - available as gt.redeye and as Cobalt Strike Logs
• smalldata - available as smalldata.redeye and as Cobalt Strike Logs
• testdata - available as Cobalt Strike Logs

You may want to use a tool like download-directory.github.io to download just one folder of a github repo
