SessionGopher

Quietly digging up sa information for PuTTY, WinSCP, FileZilla, SuperPuTTY, and RDP

SessionGopher is a PowerShell tool that finds and decrypts sa information for remote access tools. It has WMI functionality built in so it can be run remotely.
Its best use case is to identify systems that may connect to Unix systems, jump boxes, or point-of-sale terminals.

SessionGopher works by querying the HKEY_USERS hive for all users who ha onto a domain-joined box at some point. It extracts PuTTY, WinSCP, SuperPuTTY, FileZilla, and RDP sa information. It automatically extracts and decrypts WinSCP, FileZilla, and SuperPuTTY sa.
When run in Thorough mode, it also searches all drives for PuTTY private key files (.ppk) and extracts all relevant private key information, including the key itself, as well as for Remote Desktop (.rdp) and RSA (.sdtid) files.

Usage

-Thorough: searches all drives for PuTTY private key (.ppk), Remote Desktop Connecton (.rdp), and RSA (.sdtid) files.

-o: outputs the data to a folder of .cs

-iL: provide a file with a list of hosts to run SessionGopher against, each host separated by a newline. Provide the path to the file after -iL.

-AllDomain: SessionGopher will query Acti for all domain-joined systems and run against all of them.

-Target: a specific host you want to target. Provide the target host after -Target.

To run locally

To run remotely (-iL, -AllDomain, -Target)

To run remotely, you can either provide a pri account's credentials for the remote system using the -u and -p flags. If you omit the -u and -p flags,
SessionGopher will run under the security context of the account from which you run the script (e.g. if you are already logged in as DA account, or logged in as an account that
is local admin for the target system, or doing a _runas_ with either of the two, you won't need to supply credentials).

Any of these commands can be coupled with -Thorough, but note that it takes significantly longer as it queries the entire remote filesystem. It is not recommended you run in -Thorough mode when querying
more than a small set of systems at a time.

Running remotely by adding -o (print to CS nicely, as SessionGopher will accumulate all sessions it finds and tell you exactly where it found that sa.

To write to CS remote or local)

To ha create a folder to neatly contain .csvs of the extracted sessions:

... that's it.

Accessing the sa information for every user in HKEY_USERS requires local admin pri. Without local admin pri, you will still recei session
information for that user.

Sample output (-Thorough):
