TxRecon is a script that can find the connections of any two twitter users. TxRecon also uses WhatsMyName, which is a high-speed username checker written by WebBreacher.
You MUST have a twitter API key for this program to work.
To add your API key, the TxTriangulate.py file has a spot for your API keys right at the top.
python3 engine.py t1 t2
This is the generic usage of the script. If the account has a large amount of followers then you will most likely burn the API, so I'd suggest using the Mutuals Flag if you're concerned about that.
python3 engine.py t1 t2 -Mx
This will find accounts that both targets follow, and then search them using WhatsMyName. It's ideal for accounts with large amounts of followers and it's fast.
python3 engine.py t1 -Tx
This will use WhatsMyName to search for the Username specified and then place it in a text file.
