Hackers Likely Stole FBI Call Logs From AT&T That Could Compromise Informants
1 min read
Summary
The telecoms giant AT&T recently confessed to a data breach in July 2022 that exposed the call and text logs of more than 100 million customers for a period of six months.
Now the FBI has warned that the data stolen also included the communications logs of its own agents, sparking concern that the identities of anonymous sources linked to investigations may be revealed.
While the actual content of calls and texts was not revealed, the communciation logs of both agents’ mobile numbers and other phone numbers used are believed to have been exposed.
It is still unclear how widespread the dissemination of this data is, and a suspect was arrested in December 2024 over the attempted extortion of AT&T, after the company paid $370,000 to have the trove of data deleted.
The incident highlights the increasing threats from cybercriminals and nation-state hackers and the company has pledged to increase investments in its network security.
