Beladen – Elusive Web Server Exploit. (information for site owners and hosting providers)

18 Jun 09   Filed in Website exploits with 24 Comments

There has not been much buzz about the recent Beladen attack. Although some sources estimated 40,000 infected web sites, it was clearly not as prominent as the Gumblar. To my mind, it’s because of the elusive nature of the Beladen exploit. It is very difficult to detect. It works intermittently. Only a small percentage of site visitors are exposed to malicious content. Many security scanners just overlook it.  Most likely the spread of this attack is underestimated.

In this post, I’ll list every fact I know about the Beladen exploit and hope you will add any missing information in the comments. This format proved to be very fruitful in my recent post about the Gumblar exploit where your 150+ comments made my article the most informative online resource about that attack that most other sites (including major media) referred to.

I hope the information you will find here can help site owners and hosting providers understand the nature of the exploit and get rid of it.
