Paris Hilton and Lindsay Lohan's MySpace profiles breached

While the not-so-publicity-shy stars probably won't mind, and none of the photos are all that racy (except for the one of a fully dressed, provocatively posed Hilton in a tanning booth), there's a lesson for us all in this social network privacy flap du jour.

"Anything you upload to a public Web site is not private; it's public. Even if you think it is password protected," says Jeremiah Grossman, chief technology officer at White Hat Security, a Web application security company. "That's the bottom line."

The photos began making the rounds on Tuesday after computer technician Byron Ngo released them publicly, and gave Valleywag detailed instructions for his hack. Valleywag also has the photos here.

The problem has been fixed so don't bother trying to replicate it. But the breach resurrects the debate over whether the notion of privacy is outdated in a world where you party too much at an event and the next morning an embarrassing photo is up on your friend's Facebook page.

Valleywag blamed data portability, the concept underlying the sharing of data between social networks and other sites.

However, according to MySpace, it had nothing to do with data portability and everything to do with Yahoo using "deprecated mobile APIs."
