Protcheck 1.0.1 - @lockedbyte (A C utility to check an ELF binary protections parsing the ELF directly instead of using intermediate programs like readelf or grep. This tool checks for: - FORTIFY Source - NX - PIE - Canary - RELRO - Interesting imports like system or execve - Dangerous functions like gets(). Advantages of using C-based program instead of bash/python ones: - You do not depend on external programs like readelf or grep. - Avoid problems: If the program you are using changes it's output, or a user has a different language the results could get wrong. - Parsing the ELF file to check for those protections directly in C could let you understand how to find them manually and how the ELF works internally. - In some CTFs you need to use remote systems that do not have some programs like readelf or grep, using a non-dependant binary could help you to check the protections for the needed binaries.
