Man, I took way longer on this than I really needed to. Once I realized what was happening, and tread carefully, I knew right where to go. Good challenge!
I used mainly GDB and objdump for this. Also needed Capstone for some more analysis.
For anybody who’s still stuck, let me try to give some non-spoiler hints (if these count as spoilers, feel free to remove this):
Done! Great challenge.
Can anyone help me out with this? I know what is messing up my debugging, but I can’t figure out where it is going after that…
Done!
IDA free did the trick

- (GDB) Catchpoints may help you figure things out a bit.
- Read the description of the challenge, it’s important.
Very useful. Thx.
Somehow the steps that work to obtain the flag in IDA don’t work with radare2. Can somebody explain why?
Hello, Is anybody else stuck in a part of code that seems to only acces and manipulate a particular adress in memory, i’m just starting to think that the main function didn’t load properly, i don’t know if it is for a particular antidebug mechanism that i haven’t seen or what can it be… 
i got similar issue.bypass the ptrace anti-debug technique. am new to this known little gdb. some can help to fix the elf?
