I know nothing about sigscanning and I want to learn about it

fakuivan · **Author**

Hi there!

|read the title|

I've read this article and some bailopan devlogs and I still can't figure out what rules the signature has to follow or where do I get the signatures from (w or linux?), I've seen things like "\?55\x52", "*\x52" and "\x55\x52 ?x" I've heared that this article is pretty outdated and that is not helping me either. Can anyone help me with this?

btw this is the function that I want to call

CTFPlayer::PickupWeaponFromOther

The signature is not workig since the HardBreak Update

from the linux server module:

If you need a working signature, you can grab it from here. As for the rules on what to wildcard- anything that is likely to change at runtime or when the binary is recompiled. The wiki link you posted explains this.. you'll learn the rules with a better understanding of assembly. For example, the first few bytes that make up the function prologue are almost never wildcarded as they won't change unless the function parameters are changed. And if that happens, you've got bigger problems.
