Researchers Identify New Phishing Threats with DNS Attacks

Researchers at Google and the Georgia Institute of Technology are studying a virtually undetectable form of attack that quietly controls where victims go on the Internet. The study, set to be published in February, takes a close look at "open recursive" DNS servers, which are used to tell computers how to find each other on the Internet by translating domain names like google.com into numerical Internet Protocol addresses. Criminals are using these servers in combination with new attack techniques to develop a new generation of phishing attacks. What is so new about the possible attacks on DNS servers? We all know they are very vulnerable to attack because they are so visible and important to the Internet. The link for this article located at PC World is no longer available. .

Steganography Analysis of Two Million Images Finds No Hidden Messages

Following reports that bin Laden hides messages in images on the Web, a study has found no evidence that steganography has caught on. A study of more than two million images downloaded from eBay auctions appears to show little evidence that terrorists -- or indeed anybody else -- is using the images to hide encoded messages. The study, by Niels Provos and Peter Honeyman at the University of Michigan, was carried out in response to reports that terrorists are using steganography to hide their communications in images on Internet sites such as Amazon and eBay. The researchers analysed the images to look for evidence of a type of encryption called steganography, which refers to the practice of hiding the existence of a message. If an image on eBay did have a message encoded into it, it would be indistinguishable to the casual observer from the original image. The weakness of such systems, say the researchers, is that they rely on the secrecy of the encoding system. The link for this article located at ZDNet UK is no longer available. .
