📰 American Hacker In Turkey Linked To Massive AT&T Breach

An anonymous reader quotes a report from 404 Media: John Binns, a U.S. citizen who has been incarcerated in Turkey, is linked to the massive data breach of metadata belonging to nearly all of AT&T's customers that the telecommunications giant announced on Friday, three sources independently told 404 Media. [...] As 404 Media reported in January, Binns has already been indicted for allegedly breaking into T-Mobile in 2021 and selling stolen data on more than 40 million people. Now, he is allegedly connected to the latest breach against AT&T, which the company said it detected in April. The AT&T data was lifted from a Snowflake instance, a data warehousing tool, AT&T told 404 Media. Snowflake has been at the center of a series of massive and high profile breaches, including Ticketmaster and Santander. In a blog post published in June which covered a threat actor targeting Snowflake instances, cybersecurity company Mandiant said the threat actor, which it dubs UNC5537, "comprises members based in North America, and collaborates with an additional member in Turkey." In its breach announcement, AT&T said authorities had already apprehended one of the people involved in the breach. Binns was recently arrested and detained in Turkey, The Desk reported in May. That report, which is the last public information about his whereabouts, says he was detained following an extradition request from the U.S. Before he was arrested, Binns told 404 Media in January that he had "reasons to not be concerned" about being extradited.
