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):
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
ZIP file with everything:
Greets,
