UPDATED: AT&T Data Leak: What You Need to Know and How to Protect Yourself

Update:

AT&T announced a cybersecurity breach on July 12th that exposed call records and text data for a significant portion of its customer base. This includes customers on mobile virtual network operators (MVNOs) that use AT&T’s network, like Cricket, Boost Mobile, and Consumer Cellular.

The compromised data covers a period between May 1, 2022, and October 31, 2022, with a small number of records from January 2, 2023, also affected. According to AT&T, hackers gained access through a third-party cloud platform account, similar to breaches at Ticketmaster and Santander Bank.

What Information Was Exposed?

The stolen data reveals the phone numbers customers communicated with, along with the frequency and total duration of calls/texts for specific periods. However, AT&T assures customers that the content of calls or texts, timestamps, Social Security numbers, dates of birth, or other personal details were not compromised.

What AT&T is Doing

AT&T claims the data isn’t publicly available and has secured the access point used by the hackers. They’re collaborating with law enforcement to apprehend those involved, with one arrest already reported. AT&T will notify affected customers and offer resources to protect their information.

This incident follows a previous leak earlier this year that exposed data of over 70 million AT&T customers, details of that leak can be found below.

AT&T, one of the largest telecom giants, recently acknowledged a significant data leak that has affected millions of its customers. The leaked dataset, which includes personal information such as names, addresses, phone numbers, and Social Security numbers, has raised concerns about privacy and security.

The company has reset the security passcodes of affected active customers.

AT&T’s Response: AT&T is actively reaching out to affected customers via email or letter to inform them about the data that was included in the leak and the measures being taken to address the situation. The company has also initiated a thorough investigation, working with external cybersecurity experts to analyze the incident. So far, there is no evidence of authorized access to AT&T’s systems resulting in data exfiltration.
