Know Your Enemy: Malicious Web Servers

Cyber Chief Magazine brings you the tactics to uncover and neutralize the insider threat

Today, many attackers are part of organized crime with the intent to defraud their victims. Their goal is to deploy malware on a victim’s machine and to start collecting sensitive data, such as online account credentials and credit card numbers.

Since attackers have a tendency to take the path of least resistance and many traditional attack paths are barred by a basic set of security measures, such as firewalls or anti-virus engines, the “black hats” are turning to easier, unprotected attack paths to place their malware onto the end user’s machine. They are turning to client-side attacks.

This paper examines client-side attacks and evaluates methods to defend against client-side attacks on web browsers. First, it provides an overview of client-side attacks and introduces the honeypot technology that allows security researchers to detect and examine these attacks. Then it proceeds to examine a number of cases in which malicious web servers on the Internet were identified with honeypot technology and evaluates different defense methods. It concludes with a set of recommendations that one can implement to make web browsing safer.
