- Hacker Poster New Thread on a Dark Web Forum and claims to have stolen millions of plates from T-Mobile
- The registrations included names, E -mail addresses, phone numbers and other PII
- T-Mobile, however, says the archive has nothing to do with the company or its customers
Hackers have recently shared a new database that they claim contains sensitive customer information stolen from the US telecommunications giant, T-Mobile. However, the company denied any connection to the archive and said it had nothing to do with it or its clients.
ONE Cygenerws Report claims that the named cyber criminals leaked a database containing fresh Intel (obtained as early as June 1, 2025).
The database contained 64 million lines and contained valuable customer information such as full names, birth dates, taxes, postal addresses, phone numbers, e -mail addresses, device -ids, cookie ides and IP addresses.
False claims
This type of data is extremely valuable to cyber criminals who can use them to create specially designed, personalized phishing -e emails fooling the victims to share login -credentials, bankinfo and other important data. These attacks can result in identity theft, thread fraud and ransomware attacks.
Responding to one Cygenerws Inquiry, T-Mobile said the data had nothing to do with them: “Any reports of a T-Mobile data violation are inaccurate. We have reviewed the provided examples of data and can confirm that the data does not relate to T-Mobile or our customers,” the company’s representative told the publication.
The Cygenerws Team analyzed the data but could not confirm its authenticity. It said some data, such as phone numbers, appeared in previous T-Mobile links, but said it was impossible to verify the archive with 100% accuracy. We also don’t know if 64 million lines mean 64 million people.
“If this data is legitimate, 64 m lines with very sensitive information are a serious threat of identity theft/fraud, surveillance and further better targeted attacks on customers,” the team said.
This is not the first time T-Mobile refused to have been broken. For approx. A year ago, a notorious threat actor known as Intelbroker claimed to have broken into T-Mobile and stolen source code, SQL files, images, terra-form data, T- MOBILE.COM certifications and silo programs. T-Mobile denied the claims.
