I am currently learning penetration testing as part of a cybersecurity career path. I was working on a vulnhub machine that required me writing some malware to exploit a buffer overflow bug. I decided to write it in C for the sake of practicing OpSec. I used code::blocks on my machine to write the code and used tcp to transfer the compiled app to the machine. Once I tried to run it, I found that it did not have execute permissions, and the compromised user account did not have permission to use chmod, however it did have permission to use GCC. I was wondering if I uploaded the code directly to the machine and compiled it natively, would the app have execute permissions?
>Solution :
From my experience, rsync would be able to retain file permission when transferring between machines, maybe give it a try?
From local machine: rsync -aP source_path remote_machine:destination_path
-a is archive mode, preserves file properties
-P shows progress
