“Probably the most widely reported topic in the Chinese Security community this month will be the availability of a commercial MS08-067 attack pack, customized for Chinese users. On October 26th, 2008, exploit code was posted on to a well-known public repository site. In a few days, malware kit author, WolfTeeth, was quick to sell a MS08-067 port scanning tool with attack capability to his ‘customers,’ using free code from the Internet,†revealed Haowei Ren and Geok Meng Ong, from the McAfee Avert Labs.

The Carnegie-Mellon University (CMU) made available a Firefox extension developed at their School of Computer Science and College of Engineering that improves security in Firefox by protecting against man-in-the-middle attacks. The extension, named Perspectives, is available only for Firefox 3 and works on Windows, Linux (32-bit) and OS X (Intel), with support for Linux (64-bit) and Open Solaris being in the experimental stage of development.

A man-in-the-middle attack is performed by intercepting the traffic between a user and a resource that he is trying to access. This can be achieved by exploiting several vulnerabilities, like the latest DNS cache poisoning or GMail accounts hacking incidents show.

When accessing a server resource using secure protocols like SSL or SSH, a correct identification of the server is required. This is achieved through digitally signed certificates. Due to the fact that certificates issued by trusted authorities like VeriSign are expensive, it became common practice for small businesses and websites to use self-signed certificates. Read More»
