New virus to send shockwaves through internet?

Sophos Anti-Virus, a world leader in corporate anti-virus protection, has discovered the first virus capable of infecting Shockwave Flash files commonly used on popular websites.

The SWF/LFM-926 virus targets webmasters who use Shockwave to make their websites more attractive with animation and special effects. End users who browse an affected website may become infected if they download and open the Flash file on their computer.

"Computer users visiting snazzy sites would get more than they bargained for if they downloaded this virus," said Paul Ducklin, head of global support for Sophos Anti-Virus. "The Shockwave virus is not yet in the wild, but it is clear proof that virus writers continue to search for new ways to infect computer users. The best defence is to keep your security software up-to-date and practise safe computing."

Sophos recommends webmasters put in place procedures and policies to ensure the integrity of the code they place on their websites, whether it be obviously executable (in the case of, for instance, EXE and COM files) or Shockwave Flash movies.

Sophos has shared the virus securely with other anti-virus vendors to allow other analysts the opportunity to examine this new type of attack, and build protection into their respective security products.

Sophos has issued a detailed analysis and protection against SWF/LFM-926.
