Ticketmaster and multiple other companies that used Snowflake's data storage services were hacked, gaining unauthorized access to customer data. Snowflake indicated that credential theft malware or purchases of credentials on the dark web enabled hackers to access accounts that lacked multifactor authentication. Ticketmaster disclosed it identified the hack on May 20th affecting data stored through Snowflake, and a week later, hackers claimed to be selling the stolen Ticketmaster user data on the dark web. The hacks are believed to be the work of a "teen crimeware group" hacking group that regularly uses malware to steal credentials and has previously breached major companies and stolen hundreds of millions of records.
