Lambshell

An interactive shell on a lambda using a netcat reverse shell

Installation

To install, you'll need serverless framework, otherwise you can also deploy manually using the 2 publicly available layers in the serverless.yml file

$ sls deploy

Get the Shell

To obtain the shell, run the following commands

On listening server

$ sudo ncat -lv -p 8000

On local machine (params.json has the ip and port of the listening server)

$ sls invoke -f reverse --path params.json

Notes

If you're running the listener on EC2 or lightsail, remember to enable to port in your security groups.
