Syscall Handler Checker [SHC]

This tool simply verifies whether or not the system call handler system_call() has been patched to call a phony sys_call_table. If a phony sys_call_table appears to be in use, a tool like elfstat can be used for further analysis. For complete instructions read the README file included with shc*.tgz.

Compile: gcc shc.c -o shc
Usage: ./shc < System.map >
