While Mozilla Firefox may not be the default web browser for computers, a substantial number of internet users have downloaded the program. Now, cybercriminals are attacking these individuals through an unpatched exploit, reports ComputerWorld.
The flaw was uncovered on Tuesday by security program producer Norman. Cybercriminals infected a piece of code on the Nobel Peace Prize website, which could then affect Firefox users visiting the page. While the Nobel Peace Prize website has since been fixed, computers that accessed the site on Tuesday may still be infected.
"We have diagnosed the issue and are currently developing a fix, which will be pushed out to Firefox users as soon as the fix has been properly tested," Mozilla said on its official company blog.
The internet company said only Firefox 3.5 and 3.6 users were vulnerable, but did not disclose which operating systems the virus targeted.
With a growing number of Apple computers in the marketplace, the devices are coming under attack from cybercriminals more often. In response, many security vendors have begun developing antivirus software specifically for the platform.
