Update (April 19th 2009) - E!News provides additional interesting details about Josh Holly, the hacker who carried out the attack. They actually took the trouble to go to Holly's hometown and and ask people about him,providing an interesting insight into the celebs hacking phenomena.

Celebs are fast becoming a prime hacking target. Miley Cyrus already made her debut at WHID when her Twitter account was raided. But it seems that this was not her first cyber incident for her. As reported by Wired, late last year a hacker named Josh Holly published private photos of Ms. Cyrus stolen from her G-mail account.

The hack was a relatively sophisticated one and a very good example of the risks of Web 2.0. Holly penetrated a MySpace administrator using social engineering. Using the account he gained access to a list of passwords which MySpace stored in an unencrypted form. Unbelievable. Since most of us use the same password for multiple services, Holly used Cyrus' MySpace password on her G-mail account gaining access and retrieving the photographs.

In a related but yet unconfirmed story Holly claims to have used the MySpace administrative account for an advertising scam by which he gained $50,000.
