Websense announces 20,000 websites compromised

Websense sent out a news announcement on May 29, 2009, stating that over 20,000 legitimate websites were compromised with an injection of malicious javascript pointing to an exploit site.

While this announcement sounds threatening, it should have been little concern to most proxy administrators if they were running an up to date proxy that knows how to block malicious websites that are embedded in webpages. This feature is available on high end proxies (like the Blue Coat ProxySG) and allows the end-user to view the content of legitimate websites while at the same time blocking the embedded malicious website.

If you're not sure if your proxy supports blocking of embedded websites, check with your vendor soon, especially if you're at risk of hitting one of these 20,000 websites.
