Connor Riley Moucka, a 26-year-old from Kitchener, Ontario, pleaded guilty to orchestrating a sprawling extortion campaign against Snowflake customers. Moucka admitted to computer fraud and conspiracy charges related to attacks on more than 165 organizations using the cloud data warehouse platform.
The scope of Moucka's criminal activity extended far beyond Snowflake. He also confessed to stealing call and text message records belonging to over 100 million AT&T customers. This data theft represented one of the largest breaches of telecommunications customer records in recent years.
Moucka emerged as one of 2024's most consequential cybercrime actors. His operation exploited weak or compromised credentials to access Snowflake instances, then demanded ransom payments from affected organizations. The attacks disrupted multiple sectors including retail, healthcare, and technology companies. Several victims declined to pay and instead publicly disclosed the breaches.
Law enforcement linked Moucka's campaign to earlier intrusions at major retailers. The investigation traced the actor through cryptocurrency transactions, operational security lapses, and digital artifacts left during the attacks. Authorities collaborated across jurisdictions to build the case against him.
Moucka's guilty plea eliminates the need for trial and signals cooperation with prosecutors. Sentencing will follow at a later date. The plea agreement typically results in reduced sentences compared to conviction after trial, though federal charges for computer fraud and extortion carry substantial prison time.
This case reflects the evolving threat landscape for cloud infrastructure. Snowflake users rely on the platform to store sensitive business data, but shared responsibility models mean customers must enforce strong authentication and access controls. Many compromises traced back to default credentials or reused passwords from other breaches.
The AT&T data theft component adds a critical dimension. Telecommunications metadata like call and text logs reveal personal relationships and communication
