    I really like to use `git log -L :function:file`.

    It checks for modification on function() code through commit history. It is a pretty simple yet practical way to do that.

    Last days I was doing phoenix from exploit.education. After exploiting them I like to read writeups to learn new tips. To my surprise people assumed some are unexploitable due to \n on address they need to write to. Here is a tip to pass.

    Just a side note: I successfully exploited all exercises on both x86 and x64 architectures (except for final-two that seems to be unexploitable at all).

    Always remember to take into account how the binary was built. I was trying to exploit a simple format string bug using positional parameters but this was not working, until @KampetL
    remember me this. GLIBC doesn´t care about this rule, while MUSL does.
