NoNameBadge 2020 CTF
Next year I started to prepare to CTF much yearlier - as only details of upcoming CTF had become known %)
First of all I wrote my own ESP dissection software, later named ESP32knife.
Also I analyzed a set of compiled with ESP-IDF projects to extract symbol/function’s signatures.
This saved me a lot of time and allowed…
take first place, getting first blood in all tasks %))
As usually I did all task by harder way then expected - just compare my and athour’s writeups:
Also I created ESP32 reversing repository to keep all found ESP32 reversing related stuff.
Thanks for prizes (especially red badge %):
and looking forward for the NNC 2021 CTF %)
