Most of us carry a cell phone to stay in touch. But, as CBS News Science and Technology correspondent Daniel Sieberg reports, you might be surprised to learn just how easy it is to violate your privacy or even trick you.
A high-profile publicist is accused of hacking into the voice mail of some other women, including one who dated her ex-boyfriend.
Former Dolce & Gabbana publicist Ali Wise is accused of hacking into the voice mail of a romantic rival after the woman started dating Wise's ex-boyfriend.
Wise used free software called "SpoofCard" to gain access to the voice mails. The program also lets you disguise your voice and make it appear as though you're calling from a different number.
Wise's lawyer, Ed Kratt, told CBS: "SpoofCard is readily available on the Internet to anybody who wants to use it. One of the issues is whether Ali realized what she was doing was unlawful and the answer to that is clearly she did not."
Celebrities have also been tempted by SpoofCard; one case involved Lindsay Lohan.
"A few years back, Paris Hilton was using our technology to access a whole bunch of Hollywood celebrity's voicemail, including Lindsay Lohan, and we had to terminate her account for misusing it," said Meir Cohen, who makes SpoofCards.
Cohen said users must sign an agreement not to use the service illegally.
"Is this encouraging people to break the law?" Sieberg asked.
"I would not say so," Cohen responded. "I think anything can be used maliciously, but it's all in the hands of the user."
Wise faces up to four years in prison for felony computer trespassing and eavesdropping.
Sieberg explained that this technology allows you to trick people into thinking you are calling from another number.
To protect your voice mail from being hacked, Sieberg suggested setting up a password on your voice mail - even if you are calling from your own phone.
