Imperva discovers more dangerous DDoS attack threat

Web server attacks more powerful, more efficient and less traceable

SYDNEY, May 14. Imperva, the data security leader, has uncovered a new DDoS attack that appears to be more powerful, more efficient and less traceable than traditional methods.

The new threat was identified by Imperva's lab, the Application Defense Center (ADC). Already the new attack mode has compromised hundreds of web servers by turning them into bots. Unlike typical DDoS attacks that capitalise on bot-infected PCs by using the servers as the attack platforms, the hackers have created a much stronger force. Below are details of the discovery:

What it is: A new type of DDoS attack that has currently infected hundreds of web servers. Unlike traditional DDoS methods that capitalise on bot-infected PCs, the attackers have turned the web servers themselves into payload-throwing bots

How it works: Rather than use the server as a means of distributing DoS malware to PCs, attackers infect the servers themselves with a malicious DoS application. Then, using a simple software program with a dashboard and control panel, the hackers configure the IP, port and duration of an attack. The simply insert a URL they wish to attack, click and go.

Imperva was able to acquire the source code of this application - which consisted of just 90 lines of PHP code - and has screenshots . We've also witnessed an attack as it was taking place and can describe what we saw and what we learned.

Why Imperva believes this is unique:

* Although servers are typically harder to compromise than PCs, by capitalising on their greater horsepower, the hackers create a much more efficient and powerful DDoS tool using servers as the attack platform. Attack volumes are multiplied by the numbers of exploited web servers.

* By using web servers, the attackers are less detectable. Tracebacks typically lead to a lone server at a random hosting company.
