Canadian Byron Ng has found the security hole in the link between Yahoo and MySpace. Ng managed to grab Paris Hilton’s private photos off her MySpace page due to a weakness in their security model. Check out his instructions here. The blog ValleyWag detailed the exploit and posted a few of Hilton’s private images in this post. The security hole is fairly interesting. It’s not clear how long it will take Yahoo and MySpace to plug it. But it does bring up larger questions of how secure any data portability will be moving forward.
