How to check if your data was exposed in the AT&T breach
How to check if your data was exposed in the AT&T breach
[[{“value”:”
AT&T has notified US state authorities and regulators about its recent (or not) data breach, saying 51,226,382 people were affected.
For those that have missed the story so far:
Back in 2021, a hacker named Shiny Hunters claimed to have breached AT&T.
On March 20, 2024, we reported how the data of over 70 million people was posted for sale on an online cybercrime forum. The seller claimed the data came from the Shiny Hunters breach. However, AT&T denied (both in 2021 and in March, 2024) that the data came from its systems.
On March 30, AT&T reset customer passcodes after a security researcher discovered the encrypted login passcodes found in the leaked data were easy to decipher.
Finally, on April 2, 2024, AT&T confirmed that 73 million current and former customers were caught up the data leak.
Weirdly enough, in the data breach notification, AT&T says the date of discovery of the breach was March 26, 2024. AT&T has still not disclosed the source of the leak, but says the data appears to be from June 2019 or earlier.
Malwarebytes VP of Consumer Privacy, Oren Arar, describes the AT&T breach as “especially risky” because of the type of data that’s been exposed.
“SSN, name, date of birth—this is personal identifiable information (PII) that cannot be changed, and if scammers get their hands on it, it just makes their work in stealing people’s identities a lot easier. In addition, this exposed data was published on the internet – in a way that anyone could access it, and not on the dark web where you need some expertise to find it”.
