A Trojan horse exploiting a flaw in Apple’s QuickTime that was patched two weeks ago is infecting MySpace.com users' computers, collecting confidential information, including passwords, several security companies said on Monday.
The attack is reminiscent of one late last year that plagued MySpace users and forced the popular social networking site to shut down hundreds of profiles.
"This function is not strictly a bug or a vulnerability, but it is something that can be misused," According to Ivan Macalintal a research director at Trend Micro.
An Apple spokesperson said on Monday that the company patched QuickTime against the flaw in its 5 March security update. New versions for both Mac operating system X and Windows were released that day.
Helsinki-based security vendor F-Secure ticked off the pieces the Trojan horse steals: MySpace username, FriendID, MySpace Display Name and other user passwords. The data is uploaded to a server at the domain Profileawareness.com, which is a members-only forum that "provides working methods of tracking exactly who visited your MySpace profile."
Although Trend Micro could not confirm that the QuickTime update of 5 March would stymie the new attack -- his research teams are still investigating -- Macalintal said that it is often true that people don't upgrade vulnerable software. "It's common that people aren't updating right away," he said.
MySpace representatives did not return a call for comment.
