A 26-year-old Canadian national has pleaded guilty to a widespread cybercrime spree that compromised over 165 companies, resulting in the theft of billions of customer records and significant extortion demands. The U.S. Department of Justice announced the guilty plea, detailing a sophisticated operation that exploited vulnerabilities in cloud provider Snowflake.

Through the breach of Snowflake’s infrastructure, the hacker and their associates gained unauthorized access to numerous client companies, including major entities like AT&T, LendingTree, and Ticketmaster. The scale of the data pilfered is staggering, with over 100 million AT&T customers alone having their call and texting records, along with sensitive personal information such as banking details and Social Security numbers, compromised from various breaches.

The criminal enterprise reportedly amassed over $2.5 million in ransom payments and an additional $500,000 from selling stolen data on illicit online marketplaces like BreachForums. The total financial losses incurred by the victims, encompassing both companies and individuals, are estimated by the Department of Justice to be $9.5 million. Authorities highlighted the predatory nature of the hacker’s tactics, which caused substantial harm to both targeted organizations and millions of consumers.

Identified online by aliases such as Waifu and Judische, the hacker was apprehended in Canada in late 2024, shortly after the widespread Snowflake breaches came to light. Cybersecurity experts have described the individual as one of the most impactful hackers of the past year. Sentencing is scheduled for October 27, with the individual facing potential decades of imprisonment.
