PuttyHijack V1.0 - Hijack SSH/PuTTY Connections on Windows

PuttyHijack is a POC tool that injects a dll into the PuTTY process to hijack an existing, or soon to be created, connection.



This can be useful during penetration tests when a windows box that has been compromised is used to SSH/Telnet into other servers. The injected DLL installs some hooks and creates a socket for acallback connection that is then used for input/output redirection.


It does not kill the current connection, and will cleanly uninject if the socket or process is stopped.


Details


1) Start a nc listener

2) Run PuttyHijack specify the listener ip and port

3) Watch the echoing of everything including passwords





Some basic commands in this version include;


!disco - disconnect the real putty from the display!reco - reconnect it!exit - just another way to exit the injected shell
