Hello w3lh, i have a question please.

can i change real war3.exe "exeinfo" with fake when patching with your loader?

for example 1.26a has "war3.exe 03/18/11 20:03:55 471040"

need to change 471040 with custom numbers

Thanks

war.exe is a file name. 471040 is the size in bytes. Date is written in PE header. Or there is any other place this info came from?

[mezvrishvili]

yes, 471040 is file size, but i'm not sure about date. as i found out, its last modified time of the file

as its written in versioncheck.conf, its file's date/time.

exeinfo = "war3.exe ??/??/?? ??:??:?? 1568211" will match war3.exe with

filesize 1568211 but won't care about the file's date/time

i'll tell you why i need to change it.

i've compiled new loader, changed name of Game.dll with Antihack.dll, so now Antihack.dll is patched and used by game and maphack not works(all the maphacks use Game.dll)

but i need make so, that players were not able to enter the server with old loader, but only with mine.

so i gonna change pvpgn version check. allow players enter server only if war3.exe has size 111111 for example(or any custom numbers, different than real)

Thats why i wanna patch it and provide fake info, as though war3.exe has size 111111

or maybe patch game.dll and change version manually? as though its not 1.26.0.1 but 1.26.1.2 or something?

or change versionid or checksum
versionid=0x0000001a gameversion=0x011a0001 checksum=0xf2e7cec2

please share if you have any idea.
Thanks

You are just playing hide and seek game.. if any decent hacker wants to bypass your custom version he can easily do so. It can even be faked on a network level with gproxy for example. I think you are wasting your time to be honest. You can't really verify that a client is genuine in any way that is not obfuscation.

The "best" thing I can think of is to have W3 verify the client through ExtraWork but even that could be bypassed by attacking W3 directly.

yep, decent hacker can bypass it, but on my server mostly play stupid kids , that are only able to download maphack and run it :)

so any simple fix will be ok for me.

can you please provide more info about ExtraWork?

能否告訴我基於1.29找不到偏移地址嗎？
有1.29調用JASS的基址或者偏移嗎？
資料夾沒有Game.doll只有Warcraft iii

Can you tell me that the offset address cannot be found based on 1.29?
Is there a base address or offset for calling JASS in 1.29?
There is no Game.doll in the folder, only Warcraft iii
