Attorneys urge consumers to contact the firm, join fight against telecom titan for failure to protect sensitive information in cybersecurity breach

BELLEVUE, Wash.–(BUSINESS WIRE)–$TMUS #classaction–Attorneys at Seattle-based plaintiffs law firm Hagens Berman are investigating T-Mobile, following reports of a massive data breach in November 2022. If you believe you are among the 37 million people whose sensitive personal information was compromised in this incident, you can join the investigation and help hold T-Mobile accountable.

If you are a current, former or prospective T-Mobile customer, you may be affected. Fill out the form to find out your rights.

Compromised data may include billing addresses, phone numbers, email addresses, dates of birth, T-Mobile account numbers and other account information such as the number of lines on the account and plan features.

This is not the first time T-Mobile customers have had their personal information exposed to identity thieves and dark web actors. The company has disclosed eight data breaches since 2018.

The Looming Threat of Identity Theft

“T-Mobile just seems unwilling to adequately protect its customers’ data,” said Thomas E. Loeser, the Hagens Berman attorney leading the investigation. “Our research may reveal that additional sensitive information has been compromised, and the company has yet to individually notify affected customers of the data breach, as it is required to under many state laws. Identity theft can turn your life upside down, and consumers deserve the information they need to protect themselves.” Loeser is a former federal cyber-prosecutor and was a member of the Cyber and Intellectual Property Crimes Section at the U.S. Attorney’s Office in Los Angeles.

Identity theft is a very real threat T-Mobile customers are now facing, with reports indicating that up to 65% of people involved in a data breach will experience it. Victims of the November 2022 data breach will be forced to undertake the arduous process of freezing their credit with all three credit reporting agencies and pay for credit reports, credit monitoring and other preventative measures if they’re to have any hope of protecting themselves from bad actors.

What Should T-Mobile Customers Do About Their Hacked Data?

Hagens Berman’s attorneys suggest that anyone who believes they may have been affected monitor their financial accounts for any suspicious activity. T-Mobile has stated that it will be offering two years of free identity protection services, which may provide limited protection and notification of identity theft, according to the firm’s attorneys.

Experts are recommending that consumers change their T-Mobile account password and PIN and freeze their credit with all three credit reporting agencies. If you elect to use any pay service to protect yourself from identity theft because of the T-Mobile data breach, be sure to save receipts showing your payments. You may be eligible for reimbursement through future legal actions.

“Big corporations need to be held accountable for failing to protect the privacy and livelihoods of their customers,” said Loeser. “It’s unacceptable that T-Mobile put its customers in this position, and it must substantially up its security while providing genuine compensation to the consumers its negligence has already harmed.”

Hagens Berman has extensive experience litigating cases of this nature. The firm was one of only a select few chosen to help lead the case against T-Mobile for its 2021 breach, which resulted in a proposed $350 million settlement.
