But according to a study to be presented Tuesday, cellphone users in Europe and the rest of the world may be just as vulnerable as the actor Hugh Grant and other celebrities to having their personal voice mail hacked -- or worse -- because of outdated mobile network security.
In a study of 31 mobile operators in Europe, Morocco and Thailand, Karsten Nohl, a Berlin hacker and mobile security expert, found that many operators provided poor or weak defenses to protect consumers from illicit surveillance and identity theft.
Mr. Nohl said he was able to hack into mobile conversations and text messages and could impersonate the account identities of cellphone users in 11 countries using an inexpensive, 7-year-old Motorola cellphone and free decryption software available on the Internet. He has tested each mobile operator more than 100 times, he said, and has ranked the quality of their defenses.
