Standard Usage

Admin Mode

go run emulation.go -mode admin -listen 127.0.0.1:9999

The Admin mode is used to emulate the C2 infrastructure (attacker on an external network). The following functions are available:

• Execute command line actions manually
• Send a list of commands to be executed

Client Mode

go run .\emulation.go -mode client -clientconnect 127.0.0.1:9999

The client mode will receive commands or list of commands from the Admin (Or parent) interface, then execute on the operating system and send the results back.

Parent Proxy Mode

The Parent Proxy mode acts as a way to forward commands to a third machine. The parent will act as a proxy for commands and command execution results between the Admin interface and client interface.

go run .\emulation.go -mode parent -parentconnect 127.0.0.1:9999 -parentlisten 127.0.0.1:10000

List Mode

List mode allows a list of commands to be supplied and executed in sequence. It requires a file of commands on each new line in a text file. This is used in AdminList Mode.

Admin List Mode

go run -mode admin -listen 127.0.0.1:9999 -commands commandfile.txt

Client List Mode

go run emulate.go -mode clientlist -clientconnect 127.0.0.1:5555

Parent List Mode

For parent mode with a list of commands go run emulate.go -mode parentlist -parentconnect 127.0.0.1:4444 -parentlisten 127.0.0.1:5555

Admin specific Options:

-listen

-listen 127.0.0.1:4444 Choose which IP and port to listen on

-logging

-logging <filename> This will add JSON logging to a file from within the Admin interface.

This is to allow documentation of commands executed with timestamps.

Example of JSON output:

Client Mode Specific Options:

-clientconnect

The IP and port that the client should connect to.

-clientconnect 127.0.0.1:4444

Parent Specific Options:

-parentconnect

The IP and port that the parent should connect to the Admin interface on.

-parentconnect 127.0.0.1:4444

-parentlisten

The IP and port that the parent should listen on (for the client to connect).

-parentlisten 127.0.0.1:5555

Generic Options

-tls

This will add encryption to all modes. The network traffic sent and received will be encrypted with a self signed certificate supplied within the tool itself.

-skip

This will skip the ENTER requirements when launching each mode. This was added to prevent script kiddies from running the tool.

Example of program pause:

-silence

Only available in parent and client modes. -silence

This will cause the parent and client modes to not print anything to the screen.
