Hooked functions can check input arguments and modify the original function behavior. The window manager handles character conversion for you ( SendMessageA vs SendMessageW) so you don. Some applications dynamically handle the WMTEXT messages. GetWindowTextW is always able to retrieve this text.

Most top-level windows store their text here.

user32!NtUserBuildHwndList (for filtering EnumWindows output) The window text can come from two places: Unicode text 'stored internally in the HWND'.

If you write an anti-anti-debug solution, all the following functions can be hooked: The malware installs its own handler for keypress events on the keyboard. #define EVENT_SELFDBG_EVENT_NAME L"SelfDebugging"īool IsDebugged () ĭuring debugging, it is better to skip suspicious function calls (e.g. if re.match(wildcard, str(win32gui.GetWindowText(hwnd))) None: if re.match(wildcard, str(win32gui.GetWindowText(hwnd))) is not None: self.handle hwnd. It also records the foreground window title to identify where the victim types by calling the APIs GetForegroundWindow()and GetWindowText(). If the event is set, the first instance understands that a debugger is present. If kenel32!DebugActiveProcess() finishes unsuccessfully, we set the named event which was created by the first instance. In the example below, we run the second instance of our process which tries to attach a debugger to its parent (the first instance of the process).

There are at least three functions that can be used to attach as a debugger to a running process:Īs only one debugger can be attached to a process at a time, a failure to attach to the process might indicate the presence of another debugger. The following techniques let the running process manage a user interface or engage with its parent process to discover inconsistencies that are inherent for a debugged process.
