Hackers leak data of 88 million AT&T customers with decrypted SSNs; latest breach raises questions about links to earlier Snowflake-related attack.

Hackers have leaked what they claim is AT&T’s database which was reportedly stolen by the ShinyHunters group in April 2024 after they exploited major security flaws in the Snowflake cloud data platform. But is this really the Snowflake-linked data? We took a closer look.

As seen by the Hackread.com research team, the data was first posted on a well-known Russian cybercrime forum on May 15, 2025. It was re-uploaded on the same forum on June 3, 2025, after which it began circulating among other hackers and forums.

After analyzing the leaked data, we found it contains a detailed set of personal information. Each of these data points poses a serious privacy risk on its own, but together, they create full identity profiles that could be exploited for fraud or identity theft. The data includes:

Full names
Date of birth
Phone numbers
Email addresses
Physical addresses
44 Million Social Security Numbers (SSN) (43,989,219 in total)
