An unidentified malicious intruder broke into T-network Mobile’s in late November and took information on 37 million customers, including addresses, phone numbers, and dates of birth, the U.S. telecom provider announced on Thursday.
The breach was discovered on January 5, according to T-Mobile in a filing with the U.S. Securities and Exchange Commission. According to its inquiry to yet, it claimed that no passwords or PINs, bank account or credit card information, Social Security numbers, or other official identifications were among the data that had been made vulnerable to theft.
There is no proof the hacker was able to access the company’s network, but T-Mobile stated that the malicious activity “appears to be totally controlled at this time” despite the fact that its investigation is still underway. It claimed the first access to the data occurred on or about November 25.
T-Mobile claimed to have informed unnamed law enforcement and federal officials. An email asking for comment received no immediate response from it.
The business has experienced numerous hacking attempts in recent years. T-Mobile stated in its report that it did not anticipate the most recent breach to materially affect its business. Neil Mack, a senior analyst for Moody’s Investors Service, however, stated in a statement that the breach raises concerns about management’s cyber governance, may alienate customers, and may bring the Federal Communications Commission and other regulators under close examination.
Although these cybersecurity incidents may not be systematic in nature, Mack added that T-frequency Mobile’s of occurrence stands out alarmingly in comparison to its telecom competitors.
After the firm revealed in August 2021 that personal data including Social Security numbers and driver’s license information had been taken, T-Mobile agreed in July to pay $350 million to customers who filed a class action lawsuit. There were almost 80 million Americans who were impacted.
Additionally, it announced at the time that it would invest $150 million in other technologies and data security through 2023.
Prior to the August 2021 incursion, the corporation acknowledged breaches in which customer information was obtained in January 2021, November 2019 and August 2018.
After acquiring rival Sprint in 2020, Bellevue, Washington-based T-Mobile rose to prominence as one of the nation’s major providers of mobile services. After the merger, it claimed to have more than 102 million clients.
