-------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # DetectMouseEvents 2 | Detect if a mouse event was injected! 3 | 4 | This code was initially written to show how easy it is to detect those AHK-Aimbots/Pixel Aimbots, 5 | that use functions like SendMessage/mouse_event/SendInput ect... 6 | 7 | The reason why it's so easy to detect is because the WinAPI sets a flag "LLMHF_INJECTED" whenever 8 | a mouse/keyboard event was injected by a process (by calling one of the above functions for example). 9 | 10 | The code will trigger a Messagebox with the accosiated event whenever the LLMHF_INJECTED flag is set. 11 | 12 | In near future I will show you an example on how to bypass this flag using a self made mouse driver filter. 13 | --------------------------------------------------------------------------------
