A new campaign, purporting to offer a cut-price edition of Microsoft's new Windows Vista operating system, is the latest image spam which could be used to gather users' credit card information.
Experts at SophosLabs warn users of the threat posed by image spam, which uses a graphic embedded in an E-mail rather than regular text.
Image spam has become more popular among spammers and is often used to promote stock pump-and-dump scams or drugs to help with weight loss and sexual performance.
In the latest widespread campaign, image spammers are offering a bargain edition of Microsoft's new operating system, Windows Vista, and offers users a saving of $319.05.
According to Sophos, it is unclear whether acting upon the spam would furnish the computer user with a pirated edition of Windows Vista or simply steal their credit card details.
