Man arrested in Canada believed to be behind Snowflake customer breach

Canadian authorities arrested Alexander “Connor” Moucka on suspicion of orchestrating data-exfiltration attacks targeting Snowflake customers that were discovered between April and July and affected major companies including AT&T, Ticketmaster, and Santander; researchers estimated as many as 165 companies may have been impacted. The breaches involved theft of customer records and attempted extortion via criminal forums, with evidence of collaboration with other known cybercriminals (e.g., John Binns); the arrest was carried out at the request of the United States and charges have not been publicly disclosed.
