Pyoneer was created to assist with the search for sensitive information while on customer engagements. The tool has been used in different scenarios, not just for penetration testing, but that is where the tools development began. Pyoneer’s base script was written overnight while sitting in a hotel room on an engagement. The idea came while completing another script, Spyder, to ingest a CSV file and mount shares, “Wouldn’t it be great to have something to automatically scan these shares?”. A quick search for an open-source tool turned up nothing, so I began writing the foundation of the script. It was in no way ready during the engagement and the development continued at home. It took roughly a week to complete the script.
