SAN JOSE, California, September 23 /PRNewswire/ --
- In its Latest Malicious Page of the Month Report, Finjan Describes the Malicious Obfuscated Code Evolution, Including Examples of its Increased Sophistication and Effectiveness
Finjan Inc., a leader in secure web gateway products, today announced that its Malicious Code Research Center (MCRC) discovered examples of obfuscated code embedded in rich-content files, and not only in HTML-webpages on legitimate websites.
The report also covers the evolution of obfuscated code for cybercrime attacks:
- In 2005, code obfuscation consisted of character-based encoding - using any format a browser could interpret - and code scrambling - In 2006, code obfuscation became dynamic - providing a predefined function which receives as input long sets of characters - In 2007, an AJAX-based "private key" is used for de-obfuscating the code, enabling the code to be seen once- and in real-time only - In 2008, obfuscated code is not only embedded in HTML-webpages on legitimate websites, but also in rich-content files such as PDF and Flash
Online Ads and user-generated content on Web 2.0 websites are becoming more popular in directing users to malware-infected content files. Finjan's H1/2008 Web Security Survey Report indicates that 46% of respondents stated that their organization didn't have a Web 2.0 security policy in place.
According to Finjan, code obfuscation remains the preferred technique for cybercriminals for their attacks. Real-time content inspection is the optimal way to detect and block dynamically obfuscated code and similar types of advanced cybercrime techniques, since it analyzes and understands the code embedded within web content or files in real time - before it reaches the end-users.
The research is described in detail in Finjan's latest "Malicious Page of the Month" report released today.
