Empire 4 is a post-exploitation framework that includes a pure-PowerShell Windows agents, Python 3.x Linux/OS X agents, and C# agents. It is the merger of the previous PowerShell Empire and Python EmPyre projects. The framework offers cryptologically-secure communications and flexible architecture.
On the PowerShell side, Empire implements the ability to run PowerShell agents without needing powershell.exe, rapidly deployable post-exploitation modules ranging from key loggers to Mimikatz, and adaptable communications to evade network detection, all wrapped up in a usability-focused framework. PowerShell Empire premiered at BSidesLV in 2015 and Python EmPyre premiered at HackMiami 2016. BC Security presented updates to further evade Microsoft Antimalware Scan Interface (AMSI) and JA3/S signatures at DEF CON 27.
Empire relies heavily on the work from several other projects for its underlying functionality. We have tried to call out a few of those people we've interacted with heavily here and have included author/reference link information in the source of each Empire module as appropriate. If we have failed to properly cite existing or prior work, please let us know at Empire@BC-Security.org.
Empire is currently being developed and maintained by @Cx01N, @Hubbl3, & @Vinnybod. While the original Empire project is no longer maintained, this fork is maintained by @bcsecurity1. Please reach out to us on our Discord if you have any questions or want to talk about offensive security.
Empire 4 introduces a new server and client architecture which requires running each in separate terminals. Check out the Installation Page for install instructions.

Starkiller is a GUI for PowerShell Empire that interfaces remotely with Empire via its API. Starkiller can be ran as a replacement for the Empire client or in a mixed environment with Starkiller and Empire clients.
