Flash Exploiting Malware

A big batch of malware-infected ads are circulating on a slew of popular sites including MLB.com, NHL.com and the Australian site, www.whitepages.com.au. The ads were apparently bought and paid for by rogue antivirus software sellers, who posed as legitimate advertisers.

The malware is being disguised as a Flash file that has a redirect function encrypted in the file, so that when publishers upload the ad file the malware is not detectable. Once deployed on a site, the Flash file launches the malicious redirects, perhaps triggered at certain times or in certain locations.

You can see this malware exploit in action in a YouTube video
