#Semaphuck

Semaphuck is a proof of concept application designed to automate breaking programs with improper permissions on their global semaphores

This is accomplished by attempting to randomly wait and post all global semaphores

^{Inspired by an anonymous individual whose original implementation incensed an entire yeargroup}

⚠️ May cause system instability

##Compilation

Just execute make

Three builds are created:

• denum - Debug build - includes gdb debug symbols and -fstack-protector-all
• enum - Normal build
• oenum - O3 build - enables -O3, frame pointers and silences extraneous output

##Usage

Usage: ./enum [-huc]
-h, --help              This text
-u, --unattended        Continuously rescan for additional semaphores
-c, --create-mutex      Create a permissive semaphore to demonstrate what can happen

##Future work

• Make use of pthreads instead of forking to lower resource consumption
• Increase speed of mutex operations and possibly add more intentional deadlock creators
• Link with libjumper for even more fun
