Swiss telecoms giant Swisscom has admitted suffering a data breach late last year which exposed the personal details of around 800,000 customers to unauthorized parties.

The company, which is majority-owned by the government, claimed that the intruders accessed the data via a sales partner last Autumn.
Most of those affected were mobile customers, although a “few” fixed network subscribers were also hit. The number of breached customers represents around 10% of the entire population of Switzerland.
Customers’ names, addresses, telephone numbers and dates of birth were compromised. Although Swisscom maintained this data is “non-sensitive” it would be enough to give fraudsters a useful start to help craft convincing follow-on phishing attacks. That said, the firm has claimed no such activity has affected customers as yet.
