Swisscom data breach compromised personal details of 800,000 Swiss subscribers

Personal details of as many as 800,000 Swiss citizens, roughly 10 percent of Switzerland's population, were compromised last year after mobile phone operator Swisscom suffered a massive data breach.

The breach compromised names, addresses, telephone numbers and email addresses of 800,000 Swisscom customers but sensitive data like passwords, conversation or payment data were not affected.

Leading Swiss telecom major Swisscom announced yesterday that it suffered a major data breach last year after 'unknown parties' gained unauthorised access to data stored by a sales partner. The breach compromised 'non-sensitive details' of 800,000 mobile and fixed line subscribers like first and last names, home addresses, dates of birth and telephone numbers.
