Why This Matters
One of the largest cloud data breach cases highlights critical vulnerabilities in shared cloud infrastructure.
Connor Moucka, 26, a Canadian citizen, pleaded guilty on August 6, 2026 to hacking over 165 Snowflake customers, stealing billions of records including 100M+ AT&T customer records, and extorting victims for $2.5M in ransom. He faces sentencing on October 27.
The U.S. Department of Justice announced on August 6, 2026 that Connor Moucka, a 26-year-old Canadian citizen known online as 'Waifu' and 'Judische,' has pleaded guilty to hacking more than 165 companies via cloud provider Snowflake. Victims included AT&T, LendingTree, and Ticketmaster. Moucka and co-conspirators stole data from more than 100 million AT&T customers, including call and text records, banking information, driver's license numbers, and Social Security numbers. Over the course of the operation, the group received more than $2.5 million in ransom payments and approximately $500,000 from selling stolen data on forums including BreachForums. Total victim losses are estimated at $9.5 million, according to the DOJ. FBI Special Agent W. Mike Herrington called Moucka's tactics 'calculated and predatory.' Moucka was arrested in Canada in late 2024, shortly after the breaches were discovered. Google Mandiant researcher Austin Larsen previously described him as 'one of the most consequential' hackers of 2024. Sentencing is scheduled for October 27, and Moucka faces decades in prison.
