It was a Snowflake account, with stolen data including bank details for 30 million customers and other sensitive information. Lending Tree and Advance Auto Parts might also be victims.
Snowflake has not detailed how the hackers accessed the accounts, only noting that its network was not directly breached. Google-owned security firm Mandiant, involved in investigating the breaches, revealed that hackers sometimes gained access through third-party contractors but did not name these contractors or explain how this facilitated the breaches.
A hacker from the group ShinyHunters said they used data from an EPAM Systems employee to access some Snowflake accounts. EPAM, a software engineering firm founded by Belarus-born Arkadiy Dobkin, denies involvement, suggesting the hacker’s claims were fabricated. ShinyHunters has been active since 2020, responsible for multiple data breaches involving the theft and sale of large data troves.
EPAM assists customers with using Snowflake's data analytics tools. The hacker said an EPAM employee’s computer in Ukraine was infected with info-stealer malware, allowing them to install a remote-access Trojan and access the employee’s system.
They found unencrypted usernames and passwords stored in a project management tool called Jira, which were used to access and manage Snowflake accounts, including Ticketmaster’s. The lack of multifactor authentication (MFA) on these accounts facilitated the breaches.
Although EPAM denies involvement, hackers did steal data from Snowflake accounts, including Ticketmaster's, and demanded large sums to destroy the data or threatened to sell it. The hacker claimed they directly accessed some Snowflake accounts using the stolen credentials from EPAM’s employee.
The incident underscores the growing security risks from third-party contractors and the importance of advanced security measures like MFA.
Mandiant noted that many credentials used in the breaches were harvested by infostealer malware from previous cyber incidents. Snowflake’s CISO, Brad Jones, acknowledged the breaches were enabled by the lack of MFA and mentioned plans to mandate MFA for Snowflake accounts.
This incident highlights the need for robust cybersecurity practices and vigilance, particularly when dealing with third-party contractors, to safeguard sensitive data and prevent similar breaches in the future.
