这是月简发给我的一个Python版的MS08?67的一个源码，一直放在自己电脑里，因为这个漏洞太恐怖了，所以没放出来，这个脚本用来检测系统是否存在MS08-067漏洞的，现在蠕虫都有了，这个东西也没有多少危险性了，也就放在网上，供大家学习用，源码如?/p>

Tested:
* Windows 2000 Server Service Pack 0
* Windows 2000 Server Service Pack 4 with Update Rollup 1
* Microsoft 2003 Standard Service Pack 1
* Microsoft 2003 Standard Service Pack 2 Full Patched at 22nd of October 2008, before MS08-067 patch was released
Notes:
* This check might crash the SRVSVC process on Microsoft XP Service Pack 2 and 3
