Hello, I can't debug any .dll file if the plugin is installed. the breakpoint at the EntryPoint is never reached, also I tried activating the option to break on DLL load in the debugger but it didn't help.
There's no crash or anything similar, so I can't provide a crash dump or any more helpful info, sorry about that.
Fix in x64dbg: x64dbg/x64dbg#3234
Reproduction code (you need to run it on an x64dbg with the fix above, otherwise it triggers anyway):
#include <Windows.h>
#include <cstdio>
#include <cinttypes>
int main()
{
puts("");
wchar_t executablePath[MAX_PATH] = L"";
GetModuleFileNameW(0, executablePath, _countof(executablePath));
auto hNtdll = CreateFileW(L"C:\\Windows\\system32\\ntdll.dll", GENERIC_READ, 0, nullptr, OPEN_EXISTING, 0, nullptr);
printf("[AntiDebugHandle] ntdll: 0x%zX (LastError: %u)\n", (uintptr_t)hNtdll, GetLastError());
auto hExe = CreateFileW(executablePath, GENERIC_READ, 0, nullptr, OPEN_EXISTING, 0, nullptr);
printf("[AntiDebugHandle] exe: 0x%zX (LastError: %u)\n", (uintptr_t)hExe, GetLastError());
puts("");
}
You would probably need to create a fake QIODevice
(or whatever is the abstract of QFile
) and use a file mapping backend. Once you have the section mapping open you can close the file handle and things will work fine.
