Snowflake Hackers Identified and Accused of Stealing 50 Billion AT&T Records

Snowflake Hackers Identified and Accused of Stealing 50 Billion AT&T Records

The US government has accused Connor Moucka and John Binns of being the hackers who broke into AT&T’s systems and stole some 50 billion customer phone and text data.

In July, AT&T said hackers stole the phone data of “nearly all” of its mobile and landline customersas well as call and text message data, such as who contacted whom by phone or text message, but not the content of the messages. AT&T said at the time that it would notify about 110 million AT&T customers of the breach, and that the data was stolen from its systems hosted on Snowflake, a provider of cloud data analytics services.

Until the Justice Department’s indictment against the two hackers, which was filed Sunday, the total amount of stolen AT&T customer data was unknown.

The document does not mention AT&T. Instead, it lists “Victim-2,” describing it as “a major telecommunications company based in the United States,” which was hacked around April 14. When AT&T previously confirmed a breach, it said the company learned of the hack in April. 19. This means that both the description of what kind of company Victim-2 is, and the dates of the breach, match what AT&T has publicly disclosed, making it almost certain that Victim-2 is indeed AT&T.

AT&T did not respond to a request for comment.

DOJ spokesperson Emily Langlie declined to comment.

AT&T is just one of many victims who has had sensitive data stolen from their Snowflake instances. Hackers have also broken in in recent months Santander bank, TicketmasterAnd approximately 165 other business customers. All of these companies use Snowflake.

Prosecutors alleged that by breaking into the victim companies’ Snowflake instances, the hackers stole large amounts of sensitive personal and corporate data, including Social Security numbers, driver’s license numbers, passport numbers and banking information. the worst cyber attacks of the year. In some cases, the hackers also asked the victims for ransoms by threatening them with leaking the stolen information, threats they sometimes followed through on.
