上一边帖子里回顾了一下内核APC注入，代码有个地方欠妥，就没有选择合适的线程去注入，这里做了如下修改
if (*(PULONG)((PCHAR)ethreAd + TCB_TEB_OFFSET) != 0 //teb!=0
&& *((PUCHAR)ethreAd + 0x068) == 0x5 //state=5
&& *(PULONG)((PCHAR)ethreAd + 0x06c) == 0 //waitstatus=0
&& (((*(PULONG)((PCHAR)ethreAd + ALERTABLE_OFFSET) >> 5) & 1) == 1)) //alertable=1
{
KdPrint(("target ethreAd: 0x%x\n", ethreAd));
break;
}
因为我们是在进程已经存在的时候注入的，我们需要选择处于等待状态而且可唤醒的线程，但是我们最好不要手动去设置UserApcPending，这样肯定会有问题
....
else if ((Thread->State == Waiting) &&
(Thread->WaitMode == UserMode) &&
(Thread->Alertable || Thread->ApcState.UserApcPending)) {
Thread->ApcState.UserApcPending = TRUE;
KiUnwaitThread(Thread, STATUS_USER_APC, Increment);
}
...//计算整个dll映像文件的尺寸
int CalcTotalImageSize()
{
int nSize = 0;
if (m_pNTHeader == NULL)
{
return 0;
}
int nAlign = m_pNTHeader->OptionalHeader.SectionAlignment; //段对齐字节数
// 计算所有头的尺寸。包括dos, coff, pe头 和 段表的大小
nSize = GetAlignedSize(m_pNTHeader->OptionalHeader.SizeOfHeaders, nAlign);
// 计算所有节的大小
for (int i = 0; i < m_pNTHeader->FileHeader.NumberOfSections; ++i)
{
//得到该节的大小
int nCodeSize = m_pSectionHeader[i].Misc.VirtualSize;
int nLoadSize = m_pSectionHeader[i].SizeOfRawData;
int nMaxSize = (nLoadSize > nCodeSize) ? (nLoadSize) : (nCodeSize);
int nSectionSize = GetAlignedSize(m_pSectionHeader[i].VirtualAddress + nMaxSize, nAlign);
if (nSize < nSectionSize)
{
nSize = nSectionSize; //Use the Max;
}
}
return nSize;
}这究竟是为什么要这么做？映像大小不是nt头里SizeOfImage的值么？观察了一下这里的计算结果跟SizeOfImage是一样的啊。。知道的老铁剧透一下吧-，-。PE我还只了解一下基本的知识，这里这样做肯定是有什么玄机！

}上一边帖子里回顾了一下内核APC注入，代码有个地方欠妥，就没有选择合适的线程去注入，这里做了如下修改
if (*(PULONG)((PCHAR)ethreAd + TCB_TEB_OFFSET) != 0 //teb!=0
&& *((PUCHAR)ethreAd + 0x068) == 0x5 //state=5
&& *(PULONG)((PCHAR)ethreAd + 0x06c) == 0 //waitstatus=0
&& (((*(PULONG)((PCHAR)ethreAd + ALERTABLE_OFFSET) >> 5) & 1) == 1)) //alertable=1
{
KdPrint(("target ethreAd: 0x%x\n", ethreAd));
break;
}
因为我们是在进程已经存在的时候注入的，我们需要选择处于等待状态而且可唤醒的线程，但是我们最好不要手动去设置UserApcPending，这样肯定会有问题
....
else if ((Thread->State == Waiting) &&
(Thread->WaitMode == UserMode) &&
(Thread->Alertable || Thread->ApcState.UserApcPending)) {
Thread->ApcState.UserApcPending = TRUE;
KiUnwaitThread(Thread, STATUS_USER_APC, Increment);
}
...
这一段是wrk里一部分插入用户apc的代码，可以看到如过我们找到的线程合适，这里系统会自动设置这个值，而线程返回用户层时在KiServiceExit中系统会检查这个
UserApcPending，如果true才会执行用户apc。如果我们强行吧
UserApcPending置为true线程将会被强制唤醒，唤醒的原因就是STATUS_USER_APC，那么如果这个线程是不能被唤醒的，比方说他在等待另一个线程执行某个操作后才能走下去，那么此时他肯定会崩溃，就是一开始玩apc的时候经常把进程插崩掉的原因之一。另外就是这个waitstatus=0，应该是代表等待成功？这里我也没摸清具体是啥意思，只是在测试的时候这个状态为0的时候注入就没问题，各位老铁知道的话跟我讲讲啊0,0。
