According to recent findings image spam has started to decline in the last few weeks from 50 percent to approximately 20 percent, demonstrating a possible increase in the amount of spam with links to images on image hosting sites, rather than the image being included directly in the email.
"Image spam is increasingly used by spammers to lure recipients into viewing pornography, buying penny stocks or participating in get-rich-quick schemes, it can churn out hard-to-detect spam messages to a high volume of recipients, making it a highly lucrative business. It's hard to determine if this spam will continue to decline in 2007, but we do believe spammers will continue to develop similar techniques to help improve their evasion skills,"
said Patrick Hayati, Regional Director, McAfee Middle East.
Image spam, which looks just like any other text email, consists of a .jpg or .gif graphic consisting of words embedded in the picture. Although the images used in one spam campaign appear identical in most cases, each image is actually unique, making it very difficult to detect.
McAfee has developed a number of methods to proactively and accurately detect the latest image spam.
