[LEAK] MapleStory Korea Test v.1029 raw EXE w/ debuggables

[Diamondo25]

This morning, at 6:05AM, I got a message from someone that knows I do stuff with MapleStory.
He told me this (in short): Nexon fucked up, released new PDB.

And. They. Did. (a while back, actually)

Nexon actually released a V.1029.1 KMST EXE/PDB/MAP/LIB/EXP patch. In a 'Backup' folder. GREAT!!!!



(The IDB is mine.)

Parsing this thing took me 3 hours (!!!) with SSD and i7 4770k. I'm baffled.

Okay, from the start.
In patch XXXXto001029.patch, they introduced new files in a new folder called Backup.
This folder contains the files shown above (except idb). They tried to fix it in a newer version by overwriting it with a scrambled version. I just downloaded the older patch to get the files. 1 point for diamunds. 0 for Nexon.
It seems they started updating to VS 2015, that caused this leak. Not sure, though. Anyways, it contains Themida blocks (but themida was not applied). Check for the following AoB's to find pure gold (anti hack/private server/crc code):

57 4C 20 20 0D 00 00 00  00 00 00 00 57 4C 20 20

Also: 200 MB of debug data. 37MB of client bytecode. this is a full debugging database. variable names. classes. the whole thing. you cannot get closer to the sourcecode.


Just a little taste of the file:

Themida'd functions


WZ hotfixing by packet


IP check


Actual patchfile: maplestory.dn.nexoncdn.co.kr/PatchT/01030/01029to01030.patch

LOOOOOOOOOOOOOOOOOOOOOOOL.

We win the game

good job


This is the equivilant of GMS's v95 and that other KMST leak, but this KMST leak is very new, so it has EVERYTHING latest GMS has, so if you're coding latest GMS... this leak will help you A LOT if you understand it.

Fully named CField anyone? Kinesis, StarPlanet, everything you could ask for

I love you.

[maplefreak26]

Yay! This means something important and I'm not gonna pretend like I know how to use it but I know a lot of people would love this.

(For anyone curious, this is equivalent to the Heroes of Maple update. Which should be this year's Summer update for GMS)

[Twdtwd]

You don't know how happy this makes me. Great job finding this. Best release on RZ in a LONG time. =D

Pure gold!


If you know your way around IDA, and know how to implement this you could potentially become the next Extalia.

Hell yeah, latest GMS source until past warrior resistance release. Talk about a lot more class files I'll need to code tho

Now you don't have to cringe over finding the proper buffstats.

Well, I never had to :P The buffstats here cannot be accounted for in GMS tho because they're different version and by at least a few major versions

Amazing release, we will be able to do a lot more with the purity of the debug information.

Here's the raw contents of patch 01029to01030 generated with Fiel's tool, and some other mirrors files that pertain to this topic.

Anyone else unable to find CWvsContext::OnPacket?

[greenelfx]

I opened this thread expecting some random person posting fake stuff. But..holy shit.

They stopped using CWvsContext::OnPacket it looked like. It's handled in CWvsContext::UI_Toggle now I think, otherwise x-ref the functions from CWvsContext ;P
