SWF/LFM-926 is a pure virus, meaning the program infects files and can only spread when the compromised file is moved to another system.

In December 1999, the ProLin worm spread through e-mail by posing as a Flash movie, but in reality it was a simple Windows program file.

The virus is not the first to try to fool those PC users with a weakness for Flash movies. For the most part, Macromedia has been strict about security it would have been difficult for them to see this coming.' 'They have given their authoring community an ability to create increased functionality. 'It won't be a very effective spreading method if they only use Shockwave Flash,' he said, citing NAI tests that confirmed the virus will not spread when the Macromedia Flash is played in a Web browser.

Moreover, since the virus doesn't have a way to spread quickly, it's unlikely to infect a large number of PCs in its current form, said Craig Schmugar, virus research engineer for security-software maker Network Associates. The virus will infect only Windows NT, Windows 2000 and Windows XP systems, but has not yet been seen circulating the Internet. The SWF/LFM-926 virus' name is derived from the abbreviation for Shockwave Flash, as Macromedia Flash used to be known, the displayed message and the size of the file. This file-named V.COM-is run by the virus and infects all other Flash files in the current directory.

When the infected Flash movie is played, the virus displays the message '.' and drops a 926-byte DOS file onto the PC.

It's only when a Flash file or movie is played on a PC through a standalone player included with Macromedia's authoring tools for Web designers that this type of virus can actually infect a PC. 'Ninety-nine-point-nine percent of the time, people play Flash movies from the Web in their browser,' said Pete Santangeli, vice president of engineering for Flash at the San Francisco company. Macromedia went even further, calling the vulnerability through which the virus spread 'not that serious.' Flash technology, created by digital media company Macromedia, is typically used on sites to add interactive user interfaces and multimedia presentations. The SWF/LFM-926 should mainly be a concern to Web site designers who use Flash animations to add pizzazz to their sites, Cluley said. 'But whenever a new vulnerability like this is found, other copycats tend to create more malicious variants.' 'It's really a proof of concept, as opposed to something that you should lie awake at night worrying about,' said Graham Cluley, senior technology consultant for the Abingdon, England-based company. Dubbed SWF/LFM-926, the new program does little but infect Flash files on a PC when the movie is played.

The caution came after an unknown virus writer sent just such an infectious program to U.K. Antivirus companies warned PC users Tuesday that future Macromedia Flash movies could carry malicious viruses and worms.
