REDWOOD CITY, Calif. -- Tumbleweed® Communications Corp. (NASDAQ:TMWD), providers of innovative messaging security solutions, today introduced its Adaptive Image Filtering (AIF) technology, specifically designed to combat the ever-increasing amount of image spam. In recent tests, Tumbleweeds Message Protection Lab has found as much as 36 percent of all spam was image-based. Yet, it is not consistently blocked using yesterdays signature and reputation-based technologies.
Spammers are relentless at adapting their methods to circumvent existing spam filters. The latest trick has been to use images instead of text and randomize graphics to avoid signature detection, said Dr. Taher Elgamal, Chief Technology Officer at Tumbleweed. To keep up with their changing tactics, vendors must adapt and create new ways to block this time and resource draining nuisance.
