136 Chapter6·Phishing,SMishing,andVishing Notes from the Underground... Paris Hilton Hack In the past, several cellular companies allowed their customers to access their cell phone settings and voice mail without the need to insert the customer's personal iden- tification number (PIN) since the latter is stored by default in the phone settings. This means that when one calls his own number from his own number he did not have to insert the PIN to access voice mail and voice-mail settings. Therefore, if I know some- one's cell phone number, I can access their voice mail and their settings using caller-ID spoofing. Actually, this is exactly what happened in the famous Paris Hilton hack in 2005, when a teenager used caller-ID spoofing to access her voice mail. Ironically, in 2006 Hilton was accused of using the same trick to hack into Lindsay Lohan's voice mail using http://spoofcard.com a well-known caller-ID spoofing site.
