T-Mobile has disclosed a recent data breach that reportedly affected less than 1.5% of its customers. This accounts for more than a million customers, making this quite a concerning breach. However, T-Mobile mentioned in its statement that it has stepped in to stop “malicious, unauthorized access” to the data.
So what kind of data was vulnerable? T-Mobile says that customer names, billing addresses, phone numbers, account numbers, rates, plans and calling features were exposed for a while before it was ultimately fixed. The data also included something known as “customer proprietary network information”. Under current regulations, carriers have to inform their customers when this information is leaked or accessed without authority. This appears to indicate that T-Mobile wouldn’t have disclosed the data breach if not for the included customer proprietary network information.
While speaking to TechCrunch, T-Mobile also added: “We take the security of your information very seriously”. However, the company failed to disclose how the hack occurred, so there are still plenty of unanswered questions out there. As for the customers, they should be relieved by this information given the fact that the loophole appears to have been fixed.
Fortunately, the leaked information didn’t include other details like passwords or social security numbers, although having your home address leak out is considered a pretty serious breach of privacy. Cybersecurity measures need to evolve continually to keep up with the ever-growing pace of attacks. Multiple vulnerabilities have been fixed on mobile platforms, so this issue is not just limited to one company, brand or carrier.
