If you ’re an AT&T client , you have a brand new reason to hate your cellular supplier . In a turn of events that is somehow both entirely predictable and totally pitiable , the second - orotund wireless carrier in the U.S. has announced that cyber-terrorist recently steal call and text edition records belong to “ nearly all ” of its client .
“ In April , AT&T learned that client datum was illicitly downloaded from our workspace on a third - political party swarm political platform , ” the party read Friday in aSecurities and Exchange Commission revealing . “ We launched an investigation and set-aside leading cybersecurity experts to understand the nature and scope of the deplorable activity . We took steps to close off the illegal memory access power point . ”
Between April 14 and April 25 , 2024 , the hacker exfiltrated filing cabinet “ containing AT&T records of client call and text interactions that pass off between approximately May 1 and October 31 , 2022 , as well as on January 2 , 2023 , ” AT&T state . gratefully , the records that were stolen did not have identify data points . According to the company , “ personal data such as Social Security number , date of birth , or other in person identifiable entropy ” were not steal . Nor were the contents of the schoolbook and calls .

Instead , the information that was take unwrap the sound numbers that a special user called ( or was called by ) during the given stop , as well as the frequency with which those fundamental interaction occurred . The record distinguish the numbers “ with which an AT&T or MVNO wireless turn interact during these catamenia , including phone issue of AT&T wireline client and customers of other toter , counts of those interactions , and aggregate call duration for a day or calendar month , ” the disclosure reads .
In other words , the hackers seem to have stolen whole anonymized data . However , such data need not of necessity remain anonymous for long . This is something that AT&T readily let in to in its revelation : “ While the data does not include customer figure , there are often ways , using publically available online tools , to find the name tie in with a specific telephony number , ” the companionship sheepishly admits .
Once a hacker has de - anonymized your number and knows who you are , they could hypothetically do it with the numbers you ’ve interacted with , allow them to sympathise the web of people you surround yourself with and your relationships with them . In other words , what AT&T has hold without openly saying is that this rift is get it on terrible .
On the dark web , this sort of data is traded andcan be compiledwith other falling out info to create pretty comprehensive dossiers on particular people . accord to AT&T , however , the troupe says it “ does not trust that the data is publicly available , ” which is a by all odds dim way to phrase it .
“ AT&T is working with law enforcement in its drive to arrest those involved in the incident . Based on information available to AT&T , it understand that at least one somebody has been apprehended , ” the company discloses in its filing .
revelation of the breach was delayed jolly by the Justice Department , AT&T claims . “ On May 9 , 2024 , and again on June 5 , 2024 , the U.S. Department of Justice determined that … a delay in providing public revealing was warranted , ” the company ’s disclosure reads .
The timing of the hacking incident is unearthly , given that , in April , AT&T alsodisclosed a large , disjoined data breachthat impacted as many as 73 million client . Most of those customers were former customers , but some — in fact , 7.6 million — were current ones . That data breach did include personally identifiable selective information , include Social Security numbers , email addresses , phone numbers , engagement of parentage , AT&T account numbers , and AT&T passcodes .
According to AT&T ’s own timeline , the company disclosed a monumental terrible data breach in April and then , like a workweek later , put up another massive terrible data point rift . If there ’s any clear and present evidence that you should shift to Verizon ( or peradventure just toss your cell phone out a third - story window ) , this has to be it .
