忘了在哪儿看到的了，就是让pid从1开始使用OpenProcess来打开进程，然后根据得到的句柄获取进程名称．绝对的暴力方法，貌似比较有趣，因些写来一个玩玩．
实现比较简单，先提升SE_DEBUG_NAME，然后依次打开，获取进程名称就行了，不提升权限的话服务程序是打不开的，这可不太好．
关键代码如下(实在是很简单)：
for (pid=0;pid<0xFFFF;pid++) { hProcess=OpenProcess(PROCESS_QUERY_INFORMATION|PROCESS_VM_READ,0,pid); if (hProcess) { printf("Found:pid=%d\t0x%x\t",pid,pid); cnt++; //进程计数 ShowProcessPath(hProcess,szFilePath); //这个函数根据进程句柄输出进程名称 CloseHandle(hProcess); }
效果比较有意思：

从左往右依次是pid,16进制的pid,进程名称
可以看到，有一些pid虽然可以打开，但是却不能获取到进程名称．
用Windbg查看一下，原来是这样的．
以Cid=0x564为例，结果如下:

这个其实是已经退出的进程，但是其EPROCESS仍然存在，它的某些数据结构也没有销毁，因些还可以打开，其实就是僵尸进程了．这种暴力的结果好像和内核态用PsLookupProcessId暴力枚举EPROCESS的效果是一样的，据说狙剑就使用了这种方法．
至于pid到pid+3为什么都能打开一个进程，这个现在还不太清楚，等分析了OpenProcess的实现再说吧．
==========================================================================================================================================================
后记：
该方法针对断链隐藏的进程非常有效，但是对抹了PspCidTable的就没有用了，表里找不到自然打不开
至于pid到pid+3打开的是同一个进程的问题，是因为pid作为句柄，它的最低两位是作为标志位使用的，实际查找pid时需要把低两位掩去，所以pid到pid+3的结果都是一样的
但是，有可能存在一些傻傻的程序做自我保护时没有使用掩码对比，而是直接对比pid，这就导致使用pid+1到pid+3是有可能打开被保护进程的
