Hackers Steal Phone Records of 'Nearly All' AT&T Customers

Hackers broke into a cloud platform used by AT&T and accessed the phone records of "nearly all" of its cellular customers, AT&T announced on Friday.

AT&T said the stolen data contains phone numbers of both cellular and landline customers, as well as AT&T records of calls and text messages across a six-month period between May 1, 2022 and October 31, 2022.

AT&T said some of the stolen data includes more recent records from January 2, 2023 for a smaller, unspecified number of customers, as well as call records of customers with other cellular carriers that rely on AT&T's network.

Some of the records include cell site identification numbers linked to calls and texts, which can be used to work out the approximate location of where a call was made or message sent.

The downloaded data doesn't include the content of any calls or texts, or their time stamps, according to AT&T. It also doesn't have any details such as Social Security numbers, dates of birth, or other personally identifiable information.

AT&T said it learned of the data breach on April 19, and that it is unrelated to an earlier security incident in March. The company said it does not believe the data is publicly available at this time, and it continues to work with law enforcement to identify and apprehend those involved. At least one person is said to have been arrested.

AT&T told TechCrunch that the most recent compromise of customer records were stolen from the cloud data giant Snowflake during a recent spate of data thefts targeting Snowflake's customers. Other companies that have confirmed stolen data from Snowflake include Ticketmaster, QuoteWizard, and others.

Cybersecurity researchers from incident response firm Mandiant say the hacker group is mostly based in the US and those involved are financially motivated.

Here come the "pay me $750 in bitcoin or I'll tell your wife about the texts between you and your girlfriend" scams.
You don't fall for that if your girlfriend is your wife.

This is why we should all be concerned about our data in the cloud. There is no security up there… especially if China is sending up “weather” balloons and collecting phone records as it traverses some clouds. They need to have fighter jets protecting all of these companies using the clouds.

I mean you don’t even need a weather balloon. If you’re up in the mountains you can reach them easily.

?

But in all seriousness it’s concerning the number of data breaches happening. It’s practically impossible to not be affected by such breaches these days.

Obviously these hackers need to be held accountable but at this stage of our technology development, so do the companies that have been hacked. Not only for being infiltrated, but also for any future losses customers incur from this crime.

This is why I’m glad that I live in the EU. Companies are forced to actually give a **** about data security.
