Technologies Locks Down Public Proxy Web Filter Bypass
Wednesday, April 16, 2008
Leading Web Filter Vendor Offers Immediate Protection Against Popular Liverbeat.com Exploit
WebsiteGear News -- London, UK - April 16, 2008 - 8e6 Technologies, the leading independent provider of Internet filtering and insider threat management solutions for mid-size to large enterprises, announces that it has successfully blocked a common exploit used to bypass many of the popular Web filtering products in the market. These exploits, also known as "anonymisers" or "Web-based proxies," are rapidly becoming one of the most common Internet filtering and blocking work-arounds in the enterprise and pose a significant security risk to both corporate networks and the users who exploit them.
Unique in the security marketplace, 8e6 Technologies' solutions filter unsuitable content using a database of IP addresses and URLs together with Intelligent Footprint pattern recognition technology (IFT). IFT uniquely allows 8e6 to detect encrypted proxy servers, anonymisers and tunnelling software, such as that recently loaded onto liverbeat.com, ultimately preventing use of public proxies to bypass Web filters.
"8e6 Technologies' filtering solution provide a level of protection previously unseen in the marketplace - zero-day protection against Web proxy use in the enterprise," said Eric Lundbohm, vice president of marketing, 8e6 Technologies. "Traditional Internet filters such as Websense and SurfControl can only block encrypted proxies by classifying the URL in a database. This means that they may not catch and block a proxy exploit like Liverbeat.com immediately, placing companies at considerable risk from employees accessing unsuitable or malware-riddled content. Some network administrators may not even be aware that their users are bypassing the existing Web filter because the latest proxy software is so effective at hiding the user's activity."
Public proxy scripts are widely publicised on the Internet and popular mailing lists. PHProxy is one of the most popular scripts used to create public Web proxies, with thousands of sites using this and others such as Proxify, Circumventor and CGIProxy.
The proliferation of these anonymous proxy packages has taken the creation of anonymous proxies, once the domain of extremely technical users, and packaged them up as a simple to install application that nearly any Internet user can install and use immediately. A user can create a live public proxy for free in under three minutes using free Web space or even their own home PC to bypass existing Internet filters for accessing and downloading any material at their workplace.

Ian Kilpatrick, chairman of Wick Hill Group, 8e6's UK distributor, commented: "8e6's ability to effectively tackle the worrying challenge of Web-based proxies better than many traditional Internet filters confirms our belief that this is a superior product with a major role to play in the UK Web filtering market."
