AT&T NOT SURE IF NEW CUSTOMER DATA DUMP IS DÉJÀ VU

Summary from the TLDR InfoSec newsletter

AT&T is investigating claims that 86 million customer records, reportedly containing birthdates, phone numbers, addresses, and 44 million social security numbers, are being sold on cybercrime forums. The company says this appears to be repackaged data from previous breaches, possibly the 2024 Snowflake incident or an earlier 2021 theft, rather than a new hack.
