Lab 3: Inject Into Notepad

Objective: implement classic CreateRemoteThread + LoadLibrary

injection and use it to patch a message inside notepad.exe.

• Build a payload evil.dll whose DllMain pops a MessageBox (proof of execution in the target).
• Write injector.exe: OpenProcess -> VirtualAllocEx -> WriteProcessMemory -> GetProcAddress -> CreateRemoteThread.
• Launch notepad.exe, find its PID, inject.
• Extend the DLL to patch a string / hook an API so Notepad's behavior visibly changes.
