Verizon and T-Mobile are both denying recent data breaches after a cybercriminal claimed to be selling the personal records of over 100 million users from the two companies online. The seller, known as G_mic on a cybercrime forum, is offering what they say are 61 million Verizon customer records and 55 million T-Mobile customer records for sale, with the data marked as being from 2025.
Details of the Alleged Data for Sale
The dataset (3.1 GB) allegedly includes information such as full names, addresses, phone numbers, email addresses, gender, birthdates, tax IDs, IP addresses, and more, with the data labeled as current for 2025. The seller claims this set contains similar personal and contact details, including tax IDs, device IDs, cookie IDs, and full addresses, also marked as updated for 2025.
Company Responses
The company has reviewed the data samples and states that the information is old, previously posted on the dark web, and “not affiliated with our Company or customers.” Verizon denies that any new breach has occurred and asserts that the data does not originate from its systems. Similarly, T-Mobile has categorically denied any recent breach, stating, “There was no T-Mobile data breach. This data does not relate to T-Mobile or its customers.” The company says it investigated the matter weeks ago and found no evidence of a breach.
Expert and Researcher Analysis
Cybersecurity researchers, including those from SafetyDetectives, have examined samples of the data and say the structure appears authentic, but they cannot confirm if it truly belongs to Verizon or T-Mobile customers. If the data is genuine, it poses significant risks such as identity theft, phishing, financial fraud, and account takeovers, given the breadth of personal information involved. Experts note that hackers sometimes relist old data as new to create panic or profit from repeated sales.
Context and Caution
T-Mobile has a documented history of data breaches, with at least eight confirmed incidents from 2009 to mid-2025, making its customers frequent targets for cybercriminals. As of now, there is no independent confirmation that the data for sale is new or that it originated from recent breaches of either company’s systems.
Recommendations for Customers
Both Verizon and T-Mobile customers are advised to be cautious of suspicious emails, calls, or texts, monitor their financial accounts, use strong passwords with two-factor authentication, and avoid sharing personal information unnecessarily online.
