Snowflake Customers Targeted by UNC5537 Attack Path
Massive Data Breaches: 165 Snowflake Customers Affected
Attack Path UNC5537 has been used in attacks against as many as 165 Snowflake customers, revealing a significant scale of data breaches. Mandiant, a cybersecurity firm, has identified the threat group behind the breaches as UNC5537, also known as ShinyHunters.
Lack of Multifactor Authentication Contributed to Breaches
None of the affected accounts used multifactor authentication (MFA), which requires users to provide a one-time password or additional means of authentication besides a password. This lack of security measure contributed to the breaches. After the revelations, Snowflake enforced mandatory MFA for accounts and required that passwords be at least 14 characters long.
UNC5537’s Campaign of Compromise
Mandiant stated that UNC5537 has proven to be one of the most consequential threat actors of 2024. The group launched a campaign in April, systematically compromising misconfigured SaaS instances across over a hundred organizations. The operation highlighted the alarming scale of harm an individual can cause using off-the-shelf tools.
Co-Conspirator Arrested
A co-conspirator, John Binns, was arrested in June, but the status of his case remains unknown.
Other Customers Impacted
Besides Ticketmaster, other customers known to have been breached include AT&T, Santander, Pure Storage, Advance Auto Parts, Los Angeles Unified School District, QuoteWizard/LendingTree, Neiman Marcus, Anheuser-Busch, Allstate, Mitsubishi, and State Farm.
Moucka Named in Multiple Charging Documents
KrebsOnSecurity reported that Moucka has been named in multiple charging documents filed by US federal prosecutors. However, specific charges and allegations are unknown because the cases remain sealed.
Conclusion
The Snowflake breaches highlight the importance of robust security measures, including the use of multifactor authentication, to protect sensitive customer data. As the frequency and impact of data breaches continue to grow, organizations must remain vigilant and proactive in defending against cyber threats.
