某人分析:
NtSystemDebugControl读写的内存~~
关键代码如下:
.text:00402F6B mov ecx, [ecx+0Ch]
.text:00402F6E or ebx, 0FFFFFFFFh
.text:00402F71 mov edx, [ecx+eax]
.text:00402F74 mov eax, [esi+170h]
.text:00402F7A add eax, 248h
.text:00402F7F mov [esi+16Ch], edx
.text:00402F85 jo loc_40319E
.text:00402F85
.text:00402F8B push eax
.text:00402F8C mov [ebp-1Ch], ebx
.text:00402F8F call ReadSysMem
.text:00402F8F
.text:00402F94 mov ecx, [esi+16Ch]
.text:00402F9A push 10h
.text:00402F9C add ecx, 248h
.text:00402FA2 mov [esi+180h], eax
.text:00402FA8 jo loc_40319E
.text:00402FA8
.text:00402FAE push ecx
.text:00402FAF call WriteSysMem
即是将Thread->CrossThreadFlags设为0x10h(PS_CROSS_THREAD_FLAGS_SYSTEM)
硬编码XXXX
参考PSPXXXXXTHREAD的代码
NTSTATUS
PspTerminateThreadByPointer(
IN PETHREAD Thread,
IN NTSTATUS ExitStatus,
IN BOOLEAN DirectTerminate
)
/*++
Routine Description:
This function causes the specified thread to terminate.
Arguments:
ThreadHandle - Supplies a referenced pointer to the thread to terminate.
ExitStatus - Supplies the exit status associated with the thread.
DirectTerminate - TRUE is its ok to exit without queing an APC, FALSE otherwise
--*/
{
NTSTATUS Status;
PKAPC ExitApc=NULL;
ULONG OldMask;
PAGED_CODE();
if (Thread->CrossThreadFlags
& PS_CROSS_THREAD_FLAGS_BREAK_ON_TERMINATION) {
PspCatchCriticalBreak("Terminating critical thread 0x%p (in %s)\n",
Thread,
THREAD_TO_PROCESS(Thread)->ImageFileName);
}
if (DirectTerminate && Thread == PsGetCurrentThread()) {
ASSERT (KeGetCurrentIrql() < APC_LEVEL);
PS_SET_BITS (&Thread->CrossThreadFlags, PS_CROSS_THREAD_FLAGS_TERMINATED);
PspExitThread (ExitStatus);
//
// Never Returns
//
} else {
//
// Cross thread deletion of system threads won't work.
//
if (IS_SYSTEM_THREAD (Thread)) {
return STATUS_ACCESS_DENIED;
}

好旧的东西,早有人说怎么破解了.这种硬编码方式只能在xp系统上正常,。
