Question : iframe at the top of every page, static and dynamic

Hi there,

Since sometime today, a site I look after has started sending clients a malicious iframe as the first line in every file. This happens on every site on the server, for every file on that server.

It's a fully patched Server 2008, with IIS7

Any ideas?

Code Snippet:

1:

Open in New Window Select All

Answer : iframe at the top of every page, static and dynamic

OK, it was none of the above, it was actually a compromised machine on the same subnet that was spoofing as the gateway.
