+
+This is a standalone script written in Python 3 for [GTFOBins](https://github.com/GTFOBins/GTFOBins.github.io).
+You can search for Unix binaries that can be exploited to bypass system security restrictions.
+These binaries can be abused to ~~get the f**k~~ break out of restricted shells, escalate privileges, transfer files, spawn bind and reverse shells, etc...
+
+The functions are from [https://github.com/GTFOBins/GTFOBins.github.io](https://github.com/GTFOBins/GTFOBins.github.io) and all credit goes to its respective contributors.
+They are simplified (no need for environmental variables) and syntax highlighted.
