Swiss mobile phone data stolen from 800,000 customers

A Swiss mobile phone operator has said its data systems were breached late last year, compromising the contact details of about 800,000 customers.

Swisscom said the names, addresses, telephone numbers and date of birth of the customers was accessed by an unknown party, which obtained the data through a sales partner of Swisscom.

The firm said passwords, conversations and payment data were not affected and that it has not received any reports of customers suffering as a result.

Swisscom said it discovered the incident through a routine check of its activities and is carrying out an in-depth investigation.

The 800,000 customers represent almost 10% of Switzerland's overall population.
