Pwndsh is a post-exploitation framework (and interactive shell) developed in Bash shell script language. It aims to be cross-platform (Linux, Mac OS X, Solaris etc.) and with little to no external dependencies.

The script will execute several attack including:

• Private keys search in directories.
• Bindshell or reverseshell implementation.
• Open a connection to localhost at port 80 TCP and send ‘/etc/passwd’ file to test ex-filtration control.
• Test the persistence control by implementing rootshell using chmod and bash.
• The last but not least test is port scanner to verify the reconnaissance control.

The advantages that this tool works even if the Filesystem is mounted to be Read-only and it can be loaded in memory without leaving traces after rebooting the system.
