U.K. Cellphone Company Leaks Customer Data to Other Customers

Telecommunications

When customers of the U.K. cellphone company Three logged on to view their bills, some were greeted with someone else’s account information.

The company confirmed a technical issue it was still investigating, according to a Guardian report. Affected customers who logged in over the weekend saw someone else’s name, address and call history, though the company said no financial details were disclosed.  

Three has about 9 million customers in Britain.

In November, the company dealt with a data breach of almost 134,000 customers’ information in a scheme to steal high-end phones. The National Crime Agency arrested three men as part of the investigation.
