Verizon and T-Mobile Deny Data Breaches as Millions of User Records Sold Online
G_mic, a user on a cybercrime forum, claims to have breached both Verizon and T-Mobile US and stolen a large amount of data which they are selling online in CSV and JSON format. The data includes information of 61 million Verizon customers (3.1 GB) and 55 million from T-Mobile US.
As seen by Hackread.com, the user marked the data with the year “2025,” suggesting it is recent. When a forum member asked for a download link, the seller’s clear reply was “For sale.” To check its authenticity, we obtained a sample directly from the seller. After analysis, it was confirmed to contain the following information on Verizon customers
- City
- State
- County
- Gender
- ZIP code
- Full name
- Carrier name
- IP Addresses
- Phone number
- Email addresses
- Ownership Status
- Latitude and longitude
- Street address (house number, street name)
and more…
The entire 61 Million data set is being sold for just $600.
For those unfamiliar, Verizon Communications Inc. is a major telecommunications company based in New York City, and as of March 31, 2025, it serves a vast customer base of 146 million wireless subscribers, making it the largest wireless carrier in the United States.
When contacted about the alleged leak, a Verizon spokesperson reportedly stated that the company has reviewed the data and believes it to be “old data, previously posted on the dark web, and is not affiliated with our Company or customers.”
In G_mic’s post about the T-Mobile US data, the user claims it contains the personal data of 55 million customers. The data, which is currently being sold for $400, includes personal and contact details that are apparently updated for 2025.
An analysis of the sample data by Hackread.com shows it contains the following information
- Tax ID
- Gender
- Full name
- Birth date
- Device ID
- Cookie ID
- IP addresses
- Email address
- Phone numbers
- Full address (street address city state postal code county)
and more…
Hackread.com reached out to T-Mobile and a spokesperson responded promptly, denying any recent data breach. “This came up weeks ago and we investigated. There was no T-Mobile data breach. This data does not relate to T-Mobile or its customers,” the spokesperson said.
Verizon and T-Mobile users should still stay cautious as both companies are frequent targets of high-profile state-backed hackers and cybercrime forum actors. T-Mobile customers in particular should be alert since the company has a history of data breaches where hackers have stolen millions of user records over the years. From 2009 to mid-2025, there have been at least eight confirmed incidents.
