AT&T Data Breach: Steps to Protect Your Data and Privacy

The AT&T data breach 2024: A closer look at sensitive customer data

On July 12, 2024, AT&T announced that they suffered a data breach that exposed a large amount of call records and other data related to the company’s cellular customers and landline customers. As an outcome, users of such mobile providers as Cricket, Boost Mobile, and Consumer Cellular found themselves in the danger zone. AT&T reports that the leaked data covers a period from May 1, 2022, and October 31, 2022, with a small number of records from January 2, 2023, that also have been compromised.

The AT&T customer data leaks include cellular numbers and information about call durations. The breach includes records of calls and text messages. AT&T claims that other sensitive information, including IDs, Social Security numbers, and other private data has not been leaked to hackers. Nevertheless, the AT&T cybersecurity breach is a serious incident, so if you think you might have fallen victim to this attack, keep on reading to learn what you should do next.

Understanding the Breach

The recent AT&T data breach underscores the critical importance of robust data management practices, especially when dealing with third-party vendors. The breach occurred through an unnamed third-party cloud vendor that AT&T used for marketing, billing, and generating personalized video content. This vendor was supposed to delete the data in 2017 or 2018, but unfortunately, the data was still present and subsequently compromised.

The stolen data included subscriber information, bill balances, payment details, and rate plan names. This breach exposed data belonging to nearly 9 million wireless customers, including details such as the number of lines on a customer’s account and billing information from 2015 through 2017. While the breach did not include customers’ bank information, Social Security numbers, or account passwords, the exposure of such sensitive customer data is still a significant concern.

The Federal Communications Commission (FCC) concluded that AT&T was ultimately responsible for the lapse in data protection. This incident highlights the necessity for companies to have stringent data management practices, particularly when it comes to handling sensitive customer data. Ensuring that data is properly managed, securely stored, and promptly deleted when no longer needed is crucial to prevent such breaches.

Protecting Sensitive Customer Data

Protecting sensitive customer data is a top priority for companies like AT&T, which handle vast amounts of personal information every day. To ensure the security of customer data, companies must implement robust data protection measures, including limiting access to sensitive data and enforcing data disposal requirements.

The Federal Communications Commission (FCC) mandates that carriers protect the privacy and security of consumer data. Compliance with these regulations is crucial to avoid fines and reputational damage. In response to the recent data breach, AT&T has taken significant steps to enhance its data governance practices and increase supply chain integrity. This includes implementing a comprehensive information security program and conducting annual compliance audits. Additionally, AT&T is making enhancements to its data governance practices to better manage customer information and enforce stricter data management practices among its vendors.

Companies must also ensure that their vendors’ data management practices are secure and compliant with regulations. The AT&T data breach highlights the risks associated with third-party vendor breaches. To manage customer information internally, companies should implement strict access controls, encrypt sensitive data, and regularly monitor their systems for potential breaches.

The use of cloud storage and third-party vendors requires special attention, as these can be vulnerable to cyberattacks and data breaches. Companies must educate their employees on the importance of data protection and provide training on how to handle sensitive customer data. By taking these steps, companies can better protect customer data and mitigate the risks of future breaches.

The Role of Vendors in Data Management

In the wake of the AT&T data breach, the Federal Communications Commission (FCC) is intensifying its scrutiny of how businesses protect customer data throughout their supply chains. The agency is investigating data breaches involving vendors and examining data retention practices to ensure that sensitive customer data is adequately protected.

The FCC is particularly focused on whether vendors are retaining data that should have been deleted and whether companies can effectively track the data used by third parties. As part of its increased oversight, the FCC is requiring companies to limit access to sensitive customer data, track what information is shared with vendors, and enforce strict data disposal requirements.

AT&T has responded to the breach by making significant enhancements to how it manages customer information internally and implementing new requirements on its vendors’ data management practices. The company has entered into a consent decree with the government, which mandates the implementation of a comprehensive information security program and increased oversight of its third-party vendor ecosystem. This decree also requires annual compliance audits to ensure that AT&T is meeting its data protection obligations.

This incident serves as a stark reminder of the need for companies to carefully vet their vendors and ensure that they have robust data management practices in place to protect sensitive customer data. By implementing stricter oversight and compliance measures, companies can better safeguard customer information and mitigate the risks of future data breaches.

Protecting yourself after a data breach. Quick actions and long-term strategies

To safeguard yourself after the AT&T security breach, we recommend you take the following steps: 

Immediate actions

You need to do the following as quickly as possible: 

🛡️Change passwords for all online accounts. You can never be sure how much of your data went into the wrong hands. To be on the safe side, change passwords on all your online accounts as hackers are likely to make malicious use of them. 

🛡️Enable two-factor authentication (2FA) where possible. In addition to passwords updates, 2FA is also a must-do action as it will prevent hackers from accessing your devices and online accounts.

🛡️Monitor credit cards for suspicious activity. Cyber criminals often attempt to steal sensitive data to access bank accounts and credit cards to take all your money. That’s why paying attention to notifications about failed transactions or banking app authorization attempts is essential. 

🛡️Consider placing a fraud alert or security freeze on credit cards. Where possible, set these alerts to stay informed whether hackers attempt to get access to your banking accounts. 

🛡️Contact the relevant authorities if necessary. If you believe your sensitive data has been stolen after the AT&T cyber attack, inform your bank, insurance providers, and even police, so that they can take preventive measures in case hackers attempt to exploit your personal information. 

Long-term strategies

As the dust after the AT&T security data breach settles, consider taking these steps to ensure your long-term data security: 

🛡️Be cautious about sharing personal information online. The cybersecurity rule of thumb is a conscious attitude towards data you share. Do your best not to disclose your personal information such as address, ID, Social Security number, phone number, email, and the like without a sound reason. If you are not sure why a particular person or service asks for your private information, it’s better to refrain from sharing it. 

🛡️Use strong, unique passwords for each account. The more complex passwords you use, the more time hackers will need to crack them. To come up with multiple strong passwords that you can change from time to time, use password management and generation software, but make sure it commits to non-disclosure of your information to third parties. 

🛡️Avoid clicking on suspicious links or downloading attachments from unknown sources. That’s another cybersecurity rule of thumb you need to keep in mind. Any odd links and file attachments are likely to contain malware that will leak your personal information or cause damage to performance of your device. 

🛡️Keep software and devices up-to-date with the latest security patches. Hacking strategies are always evolving, which is why timely software updates are the guarantee your devices are minimally vulnerable to data breaches and other cyber attacks. Needless to say, updates aren’t a silver bullet that will protect your devices from everything, but having your operation systems versions up-to-date significantly reduces risks of hackers attempting to exploit various vulnerabilities and security loopholes. 

🛡️Use a virtual private network (VPN) app. A VPN is a number one instrument you need to shield your personal information. Any VPN app passes your Internet traffic through an isolated and encrypted tunnel, so that nobody can see what you’re doing online. In such a way, hackers and online snoopers won’t benefit from your sensitive information even though they manage to intercept it: a bunch of symbols unreadable without a special decryption key is all they can get. 

Using VPN is a critical aspect of your data security, which is why we would like to discuss it in more detail. 

The importance of a VPN in protecting your privacy

Since a VPN app makes all your Internet traffic go through an isolated tunnel to a remote server, it also offers several benefits to your online security:

👍Data interception prevention. As we have mentioned, all your Internet traffic won’t be visible to anyone. Even though hackers succeed in intercepting your data, they won’t be able to read it. 

👍Bypass censorship and geo-restrictions. By connecting to a remote server, a VPN hides your IP address and replaces it with IP of a remote server’s location. As a result, you are able to access websites and services unavailable in your real location. However, we need to warn you that doing so may be against your local laws or terms of use of a platform you try to access using a VPN app. 

👍Secure public Wi-Fi connections. Public WiFi hotspots are commonly unprotected networks accessed by everyone, including hackers. This means using public WiFi without protection can be dangerous as hackers may steal your personal information. By using VPN, all your data goes through a private channel nobody can see which means you can enjoy free public WiFi without fear for your Internet privacy.

👍Hide online activity from trackers and advertisers. Targeted ads and spam are annoying, but with VPN they won’t be a problem at all. Again, passing your traffic through a private tunnel prevents tracking of your online activity, so that advertisers simply don’t know you’re online and can’t gather information about your online behaviors. 

However, we need to advise you against using free VPN apps as they are still insecure. Around 90% of them sell your personal information to third parties and lack Domain Name System (DNS) leak protection which means they won’t guarantee you a 360-degree defense against cyber threats.
