Loved it!

Really, really, REALLY cool challenge to get into reving!

This was Easy as 10 pts, can easily be done with QR Decode + gdb only

nice

Watch out for smartphone qr code scanners - like to cut out strings ;)

Hi all, is there anyone who could give some hints? I have an elf executable file now, and I don't know what to do next.

Do a static analysis of the file. Disassemble and try to understand how it works and what it contains. You can also look at its headers, strings etc..

How did you get elf executable file? Thank you

The QR code may help a bit here. The question to ask is - "How to convert a binary file into a string?"

Excuse me!. I can't watch

You might be saving the decoded binary data as ASCII-HEX file. Use CyberChef(https://gchq.github.io/CyberChef/ ) to decode Base64 and then download(save icon on output window) the file as binary.

Very satisfying. If you have trouble, look for a book called "Practical Binary Analysis" by Dennis Andriesse. Amazing book explains everything perfectly.

I should admit that i cheet but i'm learning from You guys, so thank you
