Ok lets open IDA (freeware version of course) then this file it says the number of nodes is massive Go to options > general > graph > maximum number of nodes and go over 10000 Now you get a graph preview that draws the flag! put it in HTB flag format…read it correctly and you are done!

btw…WHERE was the steganography part?

nevermind I found it!
