I farmed tens of thousands of us dollars in modern RuneScape by unhooking the mousehook. It worked for decades.

Find call to `SetWindowsHookEx` -> Find dword (`HHOOK`) it returns -> Inject module that calls `UnhookWindowsHookEx((HHOOK)(module_base + hhook_rva));` -> profit.

Jagex has done some interesting things, but without fail, there is a blunder accompanying each.
