AT&T Data Breach Class Action Lawsuits

In March 2024, AT&T admitted to a significant data breach that exposed the personal information of approximately 73 million users. In July 2024, AT&T announced a second data breach of phone and text message records for more than 100 million customers. As a result, individual claims and AT&T data breach class action lawsuits are being pursued against the carrier by current and former customers who may be entitled to financial compensation.

Evidence has become available that indicates AT&T was aware of the first data breach as early as August 2021, yet failed to take action to protect its customers sensitive information or alert regulators of the data exfiltration.

Individuals are now signing up for the AT&T data breach lawsuit against the telecom giant for failing to take appropriate action to safeguard their current and former customers’ data. The complaints emphasize AT&T’s delays in acknowledging the breach and notifying customers, which plaintiffs argue left personal data at risk for an extended period, increasing the likelihood of identity theft and fraud.

Who Qualifies for the AT&T Class Action Lawsuit?

To qualify for the AT&T data breach class action lawsuits, you need to be either a current or former AT&T customer whose personal information was compromised as a result of the data breach.

Individuals who have received a notification from AT&T about any of their personal information being stolen due to the recent data breach may be eligible to join the lawsuit.

To determine whether you or a loved one may be eligible for an AT&T data breach lawsuit settlement, submit information about your potential claim for review by a lawyer to determine whether a settlement or lawsuit payout may be available.

AT&T Ignored Data Breach Warnings

AT&T first learned of the first data breach in August 2021, when the hacker group Shiny Hunters claimed to have accessed and intended to sell a database filled with sensitive customer data for approximately $1 million. Initially, AT&T disputed these claims, asserting that the leaked data samples shared by Shiny Hunters did not match their own records.

Instead of conducting a thorough investigation into the alleged breach and alerting customers and regulatory bodies as required by law, AT&T maintained that the breach claims were unfounded and did not notify its customers.

Almost three years later, a hacker known as “MajorNelson” publicly released the entire AT&T database for free on the dark web in late March 2024, exposing the names, addresses, phone numbers, Social Security numbers, and email addresses of approximately 7.6 million current account holders and approximately 65.4 million former account holders.

AT&T Admits to Massive Data Breach

After the data was released on March 30, 2024, a press release issued by AT&T admitted that the August 2021 data breach has exposed the names, addresses, phone numbers, Social Security numbers, and email addresses of approximately 7.6 million current account holders and approximately 65.4 million former account holders.

According to AT&T, the exposed data dates back to 2019 and earlier. However, the company has yet to identify the source of the unauthorized access to its systems that resulted in the massive exfiltration of customer data.

Despite the initial breach notification occurring years after the first alleged incident, AT&T has now begun sending Notice of Data Breach letters to customers with known compromised sensitive personal information. AT&T stated they are also offering complimentary identity theft and credit monitoring services to customers.

However, AT&T data breach lawsuits and class action claims seek additional damages on behalf of former customers raising allegations that the company failed to adequately protect consumer data, potentially leading to significant personal and financial harm for affected customers. Critics argue that despite the risks, AT&T might have prioritized the company’s commercial benefit over implementing more stringent security measures.

Second AT&T Data Breach Announced in July 2024

AT&T announced a second data breach impacting phone numbers and detailed call records of approximately 100 million customers on July 12, 2024.

The second AT&T data breach was reported to the Securities and Exchange Commission (SEC), revealing that hackers accessed the data through a cloud server provided by Snowflake, Inc., a company that stores data for AT&T and other large firms.

In addition to the SEC filing, AT&T informed its customers of the breach via a press release, indicating the breach originated several years ago but was only recently discovered.

According to AT&T, the compromised data encompasses records of phone calls and text messages for nearly all its cellular customers from May 1, 2022, to October 31, 2022, and on January 2, 2023. The data includes interactions between AT&T mobile numbers and AT&T landline numbers during these periods.

• Name
• Mailing Addresses
• Phone Number
• Social Security Number
• Date of Birth
• Phone Records
• Text Message Records

How was AT&T hacked?

For the two AT&T data breaches, the first breach was caused by hackers who accessed customer data through a cloud-based server operated by Snowflake, Inc. This server hosted data not only for AT&T but also for other major corporations.

The second breach, which involved a larger set of customer data, was also attributed to hackers exploiting vulnerabilities in AT&T’s systems

AT&T Data Breach Risks to Customers

If your personal information was stolen during the AT&T data breach, a hacker could use such information against you for;

• Identity Theft: With access to your social security number and other personal information, a hacker could potentially impersonate you to open new lines of credit, apply for loans, or obtain services in your name. This could damage your credit rating and cause financial loss.
• Financial Fraud: Hackers might access and drain your existing bank accounts, or use your information to deceive financial institutions into giving them access to your funds.
• Phishing Attacks: Using your personal details, a hacker could craft convincing phishing emails or messages that appear to come from legitimate sources. This can lead to further theft of your financial information or login credentials for various services.
• Account Takeover: With detailed personal information, it’s easier for attackers to answer security questions or request password resets on your existing accounts, ranging from social media to financial services, leading to unauthorized access.
• Tax Fraud: A hacker could use your social security number to falsely file tax returns in your name and steal tax refunds.
• Medical Identity Theft: Using your social security number and other personal details, an individual could potentially receive medical care under your identity, which can lead to medical bills charged to you and could corrupt your medical records.
• Utilities Fraud: The information could be used to set up utilities accounts (like electricity, water, and gas) in your name but at different addresses, possibly going unnoticed until debts are incurred.
• Legal Implications: Should the hacker commit crimes using your identity, you could be implicated or need to prove your innocence.
• Loss of Privacy: Knowing your home address and personal details, a hacker or malicious party could potentially harass you or even commit crimes such as stalking or burglary.
• Long-Term Security Risks: Even after the initial breach and potential immediate misuse of your information, the stolen data could be sold on the dark web, leading to ongoing risks and threats.

Real Customer Experiences: Impact of AT&T Data Breach on Fraud and Stolen Information

In the wake of the recent AT&T data breach, hundreds of customers have turned to the AboutLawsuits platform to share their firsthand accounts of the incident’s repercussions.

These AT&T data breach testimonials provide a deeply personal insight into the considerable impact of the data breach, revealing not only the vulnerabilities in personal security but also the profound effects on individual lives.

From instances of fraud to the unsettling theft of sensitive information, these stories underscore the far-reaching consequences of data security failures.

AT&T Data Breach Lawsuits

In April, a motion to transfer was submitted to the U.S. Judicial Panel on Multidistrict Litigation (JPML), requesting that all complaints filed throughout the federal district court system be consolidated for pretrial proceedings before one judge as part of an AT&T data breach lawsuit MDL (multidistrict litigation). The motion outlined the complexity of the breach and argues that consolidating the cases would help in managing the proceedings more efficiently, avoiding conflicting rulings, and easing the legal process for all parties involved.

The JPML heard oral arguments with the parties on May 30, and subsequently issued a transfer order on June 5, consolidating the claims in the U.S. District Court for the Northern District of Texas under Judge Ada E. Brown for coordinated pretrial proceedings.

Now that the MDL for the AT&T data breach lawsuits has been established, Judge Brown is expected to set a coordinated discovery schedule to investigate the release of customer information, possible preventive measures, and the duration of AT&T’s awareness of the issue.

Should negotiations fail to yield settlements for affected customers, the court may select a series of representative cases for early “bellwether” trials. These initial trials often provide insights into jury reactions to recurring evidence and testimony, influencing the broader litigation. If settlements are not reached during the MDL, individual claims may be sent back to their original U.S. District Courts for trial.

Allegations Raised in AT&T Lawsuits

The allegations raised in the AT&T data breach lawsuits focus on several key issues regarding the company’s handling of customer data:

• Negligence: Plaintiffs argue that AT&T failed to implement and maintain adequate security measures to protect customers’ sensitive personal information. This negligence is believed to have facilitated the unauthorized access and theft of data.
• Failure to Disclose Timely: There are claims that AT&T did not promptly notify affected customers about the breach, which potentially delayed individuals’ ability to take protective measures against identity theft and fraud.
• Breach of Contract: The lawsuits also allege that AT&T breached their contractual obligations to customers by failing to adequately secure their personal data, which is typically stipulated in service agreements.
• Unjust Enrichment: In some cases, the lawsuits accuse AT&T of unjust enrichment, suggesting that the company benefited financially from avoiding the costs associated with implementing adequate security measures.
• Violations of Consumer Protection Laws: Some claims specifically argue that AT&T’s actions violated specific state consumer protection laws by failing to safeguard consumer data adequately.

He further identified that someone was able to obtain a fraudulent loan for $3,579 from Navy Federal Credit Union in his name. Head claims that upon contacting AT&T to seek compensation for his financial losses and inconvenience, AT&T denied his claim and told him they would not pay for his damages.
