Guide How to determine if a binary is sub_x or non sub_x!

It's quite simple and many might already know about this but if anyone doesn't, this will help!

 

This method still involves you loading the binary into IDA unless you can somehow search functions without processing the binary.

 

Once the binary loads a bit, the top bar will become blue and Functions window will start updating. The very beginning function is what tells us if the binary is sub_x or not.

 

start -> Usually means it's sub_x

 

_main -> Usually means it's not sub_x

What is it when there is neither a start nor _main function?
