The U.S. Department of justice indicted two hackers for breaking into the systems of AT&T and several other companies.

The U.S. has indicted two individuals, Connor Moucka and John Binns, according to new documents, for hacking third-party cloud data storage and analytics company Snowflake. The Snowflake hack led to data breaches at numerous companies using the platform such as AT&T, Ticketmaster, and more than 150 other corporations.

The US government claim Moucka and Binns “devised and executed international computer hacking and wire fraud schemes to hack into at least 10 victim organizations’ protected computer networks, steal sensitive information, threaten to leak the stolen data unless the victims paid ransoms, and offer to sell online, and sell, the stolen data.”

Charges were unsealed for two men suspected of carrying out cyberattacks against customers of Snowflake Inc., providing new details about the breaches.
