Can I rely on this github repository files?












2















I recently found this GitHub repo https://github.com/userEn1gm4/HLuna, but after cloned it I note that the comparison between the file compiled (using g++) from source HLuna.cxx and the binary included in the repo (HLuna) is different: differ: byte 25, line 1. Is the provided binary file secure? I've already analyzed that in VirusTotal without any issues, but I don't have the expertise to decompile and read the output, and I've previously executed the binary provided without thinking about the risks.

Compilation is not a directly verifiable deterministic process across compiler versions, library versions, operating systems, or a number of other different variables. The only way to verify is to perform a diff at the assembly level. There are lots of tools that can do this but you still need to put the manual work in.
