A security researcher has documented malware that uses a vulnerability in Apple’s QuickTime movie player to make a computer download and run a Javascript. A MySpace account promoting a French music group is exploiting the flaw to siphon information about users visiting the page and send it to a remote server.



The perpetrators pull off the feat by embedding into their page an invisible QuickTime video that uses one Javascript to download and execute a second Javascript. It’s this second script that acts as the spyware, according to the researcher, Didier Stevens, who documents his findings here.
