Simple program considered malware - c++

I'm working on an alarm clock application. I've been testing some things with the following code:
FMOD_SYSTEM* sound;
FMOD_SOUND* son;
FMOD_System_Create(&sound);
FMOD_System_Init(sound, 32, FMOD_INIT_NORMAL, NULL);
FMOD_System_CreateSound(sound, "alarm.mp3", FMOD_CREATESAMPLE, 0, &son);
SYSTEMTIME time;
GetSystemTime(&time);
while (!(time.wHour==16 && time.wDayOfWeek==4)) {
Sleep(10000);
GetSystemTime(&time);
}
FMOD_System_PlaySound(sound, son, NULL, 0, NULL);
for (int i = 0; i < 100; i++) {
INPUT ip = { 0 };
ip.type = INPUT_KEYBOARD;
ip.ki.wVk = VK_VOLUME_UP;
SendInput(1, &ip, sizeof(INPUT));
ip.ki.dwFlags = KEYEVENTF_KEYUP;
SendInput(1, &ip, sizeof(INPUT));
}
The idea would be to pu it in the Startup folder so that it launches every time the user logs in, then waits until the specified hour. Then, it would play the sound file using the FMOD library and increase master volume. I know that my way of increasing volume is unorthodox, but I'm just testing for the moment. It works well if executed.
The problem is that my antivirus considers it malware. I've tried it under Avast and Bitdefender with the same results. It's a rather simple code that doesn't even manage files, how can it be considered a threat?
Thanks
Edit: Forgot to say that I've tested it with and without the master volume managing loop. Therefore, there should be a problem anywhere else...

SendInput in C or C++ do not mimic the keyboard exactly, is there a better function for this? [duplicate]

I wanted to write a c++ code to emulate pressing a keyboard key "A":
// Set up a generic keyboard event.
ip.type = INPUT_KEYBOARD;
ip.ki.wScan = 0; // hardware scan code for key
ip.ki.time = 0;
ip.ki.dwExtraInfo = 0;
// Press the "..." key
ip.ki.wVk = code; // virtual-key code for the "a" key
ip.ki.dwFlags = 0; // 0 for key press
SendInput(1, &ip, sizeof(INPUT));
// Release the "..." key
ip.ki.dwFlags = KEYEVENTF_KEYUP; // KEYEVENTF_KEYUP for key release
SendInput(1, &ip, sizeof(INPUT));
It works fine when I launch other program and wait to my program execute, the "A" is clicked and first program react to it. But I found that in the other application my action was somehow prevented (I can manually press "A" on keyboard, but using my program do not cause any action).
So, what I can do to make pressing "A" from program more identical to manually pressed "A" (so the second program won't recognize that it was called from program)?
I do not have source code of second program and do not know how it recognize that "A" wasn't pressed manually.
I'm sure that the window I want to react to my code is foreground, receive and block my key (so it can decide that event doesn't come from user but from program).
You can use SendInput() to send hardware scan codes as well (as opposed to virtual scan codes, which DirectInput might ignore). It's poorly documented, but SendInput() can indeed bypass DirectInput. The reason Eric's solution didn't work is he set the hardware scan code, but ended up using a virtual scan code (by setting dwFlags to 0 and wVk to non-zero).
Essentially, to do a key press you want to set:
ip.ki.dwFlags = KEYEVENTF_SCANCODE;
And to do a key release, set:
ip.ki.dwFlags = KEYEVENTF_SCANCODE | KEYEVENTF_KEYUP;
A full working sample is below and it prints the letter 'a'. You can find other scan codes here.
#define WINVER 0x0500
#include <windows.h>
using namespace std;
int main()
{
//Structure for the keyboard event
INPUT ip;
Sleep(5000);
//Set up the INPUT structure
ip.type = INPUT_KEYBOARD;
ip.ki.time = 0;
ip.ki.wVk = 0; //We're doing scan codes instead
ip.ki.dwExtraInfo = 0;
//This let's you do a hardware scan instead of a virtual keypress
ip.ki.dwFlags = KEYEVENTF_SCANCODE;
ip.ki.wScan = 0x1E; //Set a unicode character to use (A)
//Send the press
SendInput(1, &ip, sizeof(INPUT));
//Prepare a keyup event
ip.ki.dwFlags = KEYEVENTF_SCANCODE | KEYEVENTF_KEYUP;
SendInput(1, &ip, sizeof(INPUT));
return 0;
}
Note: You can combine keypresses (like, shift + a for A) by passing SendInput() an array of INPUT structures.
You often need to set the scan code:
// Set up a generic keyboard event.
ip.type = INPUT_KEYBOARD;
ip.ki.wScan = MapVirtualKey(code, MAPVK_VK_TO_VSC); // hardware scan code for key
ip.ki.time = 0;
ip.ki.dwExtraInfo = 0;
// Press the "..." key
ip.ki.wVk = code; // virtual-key code for the "a" key
ip.ki.dwFlags = 0; // 0 for key press
SendInput(1, &ip, sizeof(INPUT));
And building an array as IInspectable suggests is also definitely the way to go.
If you are looking to create a game bot, have you looked at the program AutoHotKey?
http://www.autohotkey.com/
It offers a scripting language, that allows you to do a lot of the tasks involved in 'bot' creation and it's rather easier than trying to do it all in C++
(It certainly played Farmville for me, when all my family pressured me into creating an account)

Sending Mouse Click to DirectX Game Running as Admin

I have been building a gaming-related program that needs to send simulated input to the game (which is the top window on the screen and runs in fullscreen mode). After some struggling, I finally got mouse movements (cursor drag) and keyboard input working, but for some reason, the game will not respond to simulated mouse clicks.
I have tried the following:
#if TRUE // SendInput works for keyboard simulation and mouse drag, but not clicks:
INPUT mouse = {0};
mouse.type = INPUT_MOUSE;
mouse.mi.dwFlags = MOUSEEVENTF_LEFTDOWN;
SendInput(1, &mouse, sizeof(INPUT));
Sleep(100);
ZeroMemory(&mouse, sizeof INPUT);
mouse.type = INPUT_MOUSE;
mouse.mi.dwFlags = MOUSEEVENTF_LEFTUP;
SendInput(1, &mouse, sizeof(INPUT));
#else // tried this, but it did not work:
mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
Sleep(75);
mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);
#endif
The first dilemma I faced was sending the messages in general, but I realized this issue was caused by game process privileges > sending application privileges. After this, I encountered another problem with keypresses only registering on certain game windows/screens, but after some searching, I was able to use scancodes to overcome this. For example:
void SendSpacePress(bool bHardwareLevel){
INPUT space = {0};
space.type = INPUT_KEYBOARD;
space.ki.time = 0;
space.ki.dwExtraInfo = 0;
if(!bHardwareLevel){
space.ki.wVk = VK_SPACE;
}else{
space.ki.wScan = 0x39; // physical keyboard scan code
}
space.ki.dwFlags = bHardwareLevel ? KEYEVENTF_SCANCODE : 0;
SendInput(1, &space, sizeof(INPUT));
Sleep(rand()%25 + 25);
space.ki.dwFlags = bHardwareLevel ? KEYEVENTF_SCANCODE | KEYEVENTF_KEYUP : KEYEVENTF_KEYUP;
SendInput(1, &space, sizeof(INPUT));
}
I have also been able to do mouse movement using INPUT like below:
void PanMouse(){
INPUT mouse = {0};
mouse.type = INPUT_MOUSE;
mouse.mi.time = 0;
mouse.mi.mouseData = 0;
mouse.mi.dwExtraInfo = 0;
mouse.mi.dwFlags = MOUSEEVENTF_MOVE;
mouse.mi.dx = rand()%10 -5;
mouse.mi.dy = rand()%10 -5;
SendInput(1, &mouse, sizeof(INPUT));
}
Now the big problem is the game refuses to register my simulated mouse clicks. I would preferably like a way to send the mouse inputs without having to dive into hooking. (The game has multiple client-side anti-cheat mechanisms, so I would venture to guess that any kind of foreign process hooking or DLL injection would trigger the protection.) From what I have read, I might need to write a custom driver for a simulated hardware mouse so the input comes at the kernel level. Not a preferable option, but if need be, sobeit. (And if need be, can anyone provide helpful information for this? I have never messed around with writing drivers, but there's a first time for everything I suppose.)
TL;DR: What do I need to do to get simulated mouse clicks to register in a game that seems to ignore non-hardware input? (I.e., how can I trick the game into thinking mouse clicks are legitimate similarly to using KEYEVENTF_SCANCODE when simulating keyboard input?)
Instead of sleeping between inputs, you need to inject a pair of mouse inputs together with the time member appropriately set to indicate "how long".
Here's something close to what you want. This will click the current cursor position with the left mouse simulated for 100ms.
INPUT inputs[2] = {};
inputs[0].type = INPUT_MOUSE;
inputs[0].mi.time = 0;
inputs[0].mi.dx = 0;
inputs[0].mi.dy = 0;
inputs[0].mi.dwFlags = MOUSEEVENTF_LEFTDOWN;
inputs[1].type = INPUT_MOUSE;
inputs[1].mi.time = 100;
inputs[1].mi.dx = 0;
inputs[1].mi.dy = 0;
inputs[1].mi.dwFlags = MOUSEEVENTF_LEFTUP;
SendInput(2, inputs, sizeof(INPUT));
The mouse event won't happen immediately. It gets "queued" to happen shortly afterwards.
You should use the same technique for your keyboard events. Don't call "Sleep".

C Virtual Keyboard Input selectively working

I am working a on project that needs virtual input which is being coded in Microsoft Visual Studios using the windows.h header. To do this I am using the keybd_event() method and the VkKeyScan() method:
keybd_event(VkKeyScan('w'), 0, 0, 0);
keybd_event(VkKeyScan('w'), 0, KEYEVENTF_KEYUP, 0);
However, the virtual input is only being recognized by some programs, such as Notepad, Command Prompt, browsers, and other applications that use text fields. The purpose of virtual input for my project is to use a client to control "VisualGameBoyAdvance" which takes keyboard input that is then translated into a command such as 'w' = start, 'z' = a button, etc.
Why is the virtual input being read when using applications in text fields, but not as commands? Are there alternative methods of the windows.h header file or are there better methods in the header?
Update: I have been trying to use VkKeyScanEx() as an alternative method for taking virtual input as a shot-in-the-dark effort. How to I specify my input locale identifier? I have been trying to use UTF-8 and en_AU.UTF-8, with no luck. Is there a chart that translates how to specify this?
I've also tried using
keybd_event(GetKeyState('w'), 0, 0, 0);
keybd_event(GetKeyState('w'), 0, KEYEVENTF_KEYUP, 0);
Which did not work at all and tried
while(1){
/*Sleep(1000);
keybd_event(GetKeyState('w'), 0, 0, 0);
keybd_event(GetKeyState('w'), 0, KEYEVENTF_KEYUP, 0);*/
// Pause for 5 seconds.
Sleep(500);
// Set up a generic keyboard event.
ip.type = INPUT_KEYBOARD;
ip.ki.wScan = 0; // hardware scan code for key
ip.ki.time = 0;
ip.ki.dwExtraInfo = 0;
// Press the "W" key
ip.ki.wVk = 0x57; // virtual-key code for the "a" key
ip.ki.dwFlags = 0; // 0 for key press
SendInput(1, &ip, sizeof(INPUT));
// Release the "A" key
ip.ki.dwFlags = KEYEVENTF_KEYUP; // KEYEVENTF_KEYUP for key release
SendInput(1, &ip, sizeof(INPUT));
// Exit normally
}
The problem was that the game was running though DirectX, which prevented virtual keyboard strokes. By rending the game right from the sys, it avoided directx all together and worked fine :)
