How to Know if You Were Affected by the AT&T Data Breach and What to Do Next

In a significant breach disclosed on July 12, 2024, AT&T announced that the call and text records of nearly all its cellular customers were exposed due to unauthorized access to a third-party cloud platform. At Soluify™, we understand the concerns this breach may raise for our clients and the general public. Here, we provide a comprehensive guide on understanding the breach, identifying if you were affected, and the steps to take to protect your information.

Overview of the AT&T Data Breach

AT&T revealed that between May 1, 2022, and October 31, 2022, and on January 2, 2023, customer data was illegally downloaded from their workspace on the Snowflake cloud platform. The breach compromised telephone numbers, records of calls and texts, and for some, associated cell site identification numbers. Importantly, the breach did not include the contents of calls or texts, Social Security numbers, dates of birth, or other personally identifiable information.

Who Was Affected?

The breach affected:

• AT&T cellular customers.
• Customers of mobile virtual network operators (MVNOs) using AT&T’s wireless network.
• AT&T landline customers who interacted with these cellular numbers.

AT&T has pledged to notify affected customers via text, email, or U.S. mail. You can also check your account online to see if your data was compromised.

What Type of Data Was Exposed?

The exposed data includes:

• Telephone numbers involved in interactions.
• Records of calls and text interactions.
• Cell site identification numbers for some records, which could indicate geographic locations.

While the data does not include the content of communications or personal information like Social Security numbers, it could still be used to piece together patterns and connections between individuals.

Steps to Take If You Were Affected

1. Remain Vigilant: Be cautious of any unsolicited phone calls or text messages requesting personal information. Do not respond to suspicious texts; instead, forward them to AT&T for assistance.

2. Monitor Your Accounts: Regularly review your credit reports and bank statements for any unauthorized activities. You can access free credit reports at annualcreditreport.com.

3. Report Fraud: If you suspect fraud on your AT&T account, contact AT&T’s fraud team immediately. For other accounts, reach out to the respective customer service numbers.

4. Credit Monitoring and Alerts: While AT&T has not offered additional identity theft protection, you can place a free credit freeze or fraud alert on your accounts to prevent unauthorized access.

5. Update Security Practices: Ensure your online accounts have strong, unique passwords. Enable two-factor authentication where possible for an added layer of security.

Historical Context: Previous AT&T Data Breaches

This recent breach is not an isolated incident. AT&T has faced significant data breaches in the past, which highlight the importance of robust cybersecurity measures:

• March 2024 Breach: Earlier this year, AT&T experienced a breach affecting over 7.6 million current customers and 65 million former customers. The compromised data included names, addresses, mobile phone numbers, dates of birth, and Social Security numbers. Despite initial denials, AT&T confirmed the breach and began notifying affected individuals (Malwarebytes).

• 2023 Vendor Breach: In 2023, AT&T disclosed that information belonging to 9 million customers was compromised due to a breach involving one of its third-party vendors. This incident exposed sensitive customer information and raised serious concerns about third-party cybersecurity practices (Potter Handy).

• 2014 Settlement: In 2014, AT&T settled an FCC investigation concerning privacy violations by paying a $25 million fine. This settlement was prompted by the exposure of approximately 280,000 customers’ names along with either full or partial Social Security numbers (Potter Handy).
