Earlier this week, the data of over 70 million people was posted for sale on an online cybercrime forum. The person selling the data claims it stems from a 2021 breach at AT&T. <\/p>\n
Back in 2021, a hacker named Shiny Hunters claimed to have breached AT&T<\/a> and put the alleged stolen data up for sale for $1 million for a direct sell. Fast forward three years and another threat actor calling themselves MajorNelson has leaked what they say is the same data.<\/p>\n However, AT&T denies (both in 2021 and, now, in 2024) that the data came from its systems, telling BleepingComputer<\/a> that it’s seen no evidence of a breach. No response was received to a follow-up question on whether the data could come from a third-party provider.<\/p>\n The data posted online includes names, addresses, mobile phone numbers, date of birth, social security numbers, and other internal information. Almost the same set was offered for sale in 2021, but the encrypted date of birth and social security numbers have since been decrypted and added to the set as supplemental files for most records.<\/p>\n Several sources<\/a> have verified the dataset (or parts thereof) contains valid data.<\/p>\n AT&T still hasn’t confirmed that the data came from its systems, nor from a third party. However, there are some general actions you can take if you are an AT&T customer:<\/p>\n Our Digital Footprint records now include the AT&T data so you can check if your information has been exposed online. Submit your email address (it\u2019s best to submit the one you most frequently use) to our\u00a0free Digital Footprint scan<\/a> and we\u2019ll send you a report.<\/p>\nWhat to do<\/h2>\n
