WinLicense v3.2.2 (Window Function Through an External Plugin)

This is a WinLicense 3.2.2/sample, set by default, without adding an SDK in the source code, only adding a window function through an external plugin. I don't know if bypass can be cracked, I tested it and it doesn't. Shedding may be more complicated.Please use your own way to crack it. Whether it's molting, bypass, or keygen, they are all the best methods. No need to upload your proposal, posting a picture is the best answer. I will strive to learn towards your achievements.

This plugin is much more powerful than the original WinLicense. 80-90% of people can’t get around it!

Among the anti-debug techniques, there's an interesting one worth noting.

A dummy thread is created and then it calls Sleep(0x32).
(The goal is for the created thread to be detected by tools like x64dbg.)

Then, it calls NtQueryObject with the ObjectBasicInformation class using the thread handle.

If the returned HandleCount is greater than 1, it determines that debugging is in progress.

 

void dummy()
{
	Sleep(8000);
}

bool CheckCreateThreadHandleCount()
{
	HANDLE hThread = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)dummy, NULL, 0, NULL);
	if (hThread == NULL)
	{
		return false;
	}

	Sleep(0x32);

	PUBLIC_OBJECT_BASIC_INFORMATION objInfo;

	NTSTATUS status = NtQueryObject(hThread, ObjectBasicInformation, &objInfo, sizeof(objInfo), NULL);

	if (!NT_SUCCESS(status))
	{
		CloseHandle(hThread);
		return false;
	}

	std::cout << "Handle Count: " << objInfo.HandleCount << std::endl;

	if (objInfo.HandleCount > 1)
	{
		CloseHandle(hThread);
		return true;
	}

	CloseHandle(hThread);
	return false;
}

You are wonderful.

time to add new anti-dbg trick into ScyllaHide plugin !?!?

 

I have also released a simple demo WL plugin. This is a protected example.

Could you upload it to mediafire, mega or google drive? i am not from china and i have not been able to download your examples. If you can upload the plugin and the protected example would be great, thank you.

@bootHi~ Expert, can Lengyue's WinLicense v3.2.2 be bypassed? If not, can you try my default encryption version?

smth is wrong with your code

I tried sample consle app and it prints 2 when  being ran without debugger and  4  when unde4 MS VS...

are you sure this is reliable new anti-debug way?

thanks, I see updated algo above, I'll give it a try today

 

OK, 2nd function OK but IMHO it's risky to use it, here is why:

NtQueryObject:

- This function may be changed or removed from Windows without further notice.

- This function has no associated header file or import library. You must use the LoadLibrary or GetProcAddress function to dynamically link to Ntdll.dll.

- not clear what Windows versions supports it (no info in MSDN)

- if you try the ObjectTypeInformation type you'll get error 0xc000004

OK! sounds better
