March 2007
FORT LAUDERDALE, Fla. � March 15, 2007 � BitDefender�, an award-winning provider of antivirus software and data security solutions, announced today the availability of a new whitepaper entitled �Fighting Image Spam.� The whitepaper details the sharp increase in image spam and the methods in which BitDefender detects image spam and protect consumers.
"Image spam has increased to 30-40% of the total amount of circu�lating spam, with random noise changing with almost every image sent,� said Bogdan Dumitru, BitDefender CTO. �Detection rates have dropped even further, from more than 97% to almost 65-75%. �Because spammers are using new techniques of image poisoning to defeat spam filters, there is a great need for security vendors to develop more reliable detection methods. BitDefender has spearheaded the efforts at fighting image spam with its new SID (Spam Image Distance) filter, which ignores text within images and instead learns by experience some common characteristics of the images.�
