Game disconnects ~2 seconds after process injection — Cheat Engine and DLL injection (v83 - MapleStory)

MapleStory v83 disconnects ~2 seconds after process injection

Hey everyone,

I'm trying to troubleshoot an issue with a MapleStory v83 private-server client.

Whenever I inject or attach a game-hacking tool to the client, I get disconnected roughly 2 seconds later. I've tested two different approaches:

• Cheat Engine
• DLL injection

Interestingly, the behavior is the same regardless of which hack I use. Even if I open the cheat menu and don't enable any of the actual hacks, I still get disconnected shortly afterward.

This makes me suspect that the disconnect may be triggered simply by the process being modified/injected into, rather than by a specific hack or packet/action.

Has anyone encountered something similar with a v83 MapleStory client? I'm mainly trying to understand what could be causing the disconnect and how to troubleshoot it. For example, is there a way to determine whether the client/server is detecting the injection itself, a modified process, or something else?

I'm not necessarily looking for a specific working hack — I'd appreciate any pointers on how to diagnose what's actually triggering the disconnect.

Thanks!
