A LendingTree spokesperson confirmed in a statement to WIRED that the company uses Snowflake “for our business operations” and that the company was notified that its QuoteWizard subsidiary “may have had data impacted by this incident.” LendingTree’s spokesperson says an internal investigation is ongoing. “As of this time, it does not appear that consumer financial account information was impacted, nor information of the parent entity, LendingTree,” the spokesperson says.
Since Snowflake acknowledged that accounts had been targeted, it has provided some more information about the incident. Brad Jones, Snowflake’s chief information security officer, said in a blog post that threat actors used login details to accounts that had been “purchased or obtained through infostealing malware,” which is designed to pull usernames and passwords from devices that have been compromised. The incident appears to be a “targeted campaign directed at users with single-factor authentication,” Jones added.
Jones’ post said Snowflake, alongside cybersecurity companies CrowdStrike and Mandiant, which it employed to investigate the incident, did not find evidence showing the attack was “caused by compromised credentials of current or former Snowflake personnel.” However, it has found one former employee’s demo accounts were accessed, claiming they did not contain sensitive data.
When asked about potential breaches of specific companies’ data, a Snowflake spokesperson pointed to Jones’ statement: “We have not identified evidence suggesting this activity was caused by a vulnerability, misconfiguration, or breach of Snowflake’s platform.” In a follow-up statement, the company clarified what it meant by “breach”: “Any of our customer’s accounts that were accessed as the result of leaked credentials are not caused by … Snowflake,” a spokesperson said. (Security company Hudson Rock said it removed a research post including various unverified claims about the Snowflake incident after receiving a legal letter from Snowflake).
The US Cybersecurity and Infrastructure Security Agency has issued an alert about the Snowflake incident, while Australia’s Cyber Security Center said it is “aware of successful compromises of several companies utilizing Snowflake environments.”
Unclear Origins
Little is known about the Sp1d3r account advertising data on BreachForums, and it is not clear whether ShinyHunters obtained the data it was selling from another source or directly from victims’ Snowflake accounts—information about a Ticketmaster and Santander breach was originally posted on another cybercrime forum by a new user called SpidermanData.
The Sp1d3r account posted on BreachForums that the 2 terabytes of alleged LendingTree and QuoteWizard data was for sale for $2 million; while 3 TB of data allegedly from Advance Auto Parts would cost someone $1.5 million. “The price set by the threat actor appears extremely high for a typical listing posted to BreachForums,” says Chris Morgan, a senior cyber-threat intelligence analyst at security firm ReliaQuest.
Morgan says the legitimacy of Sp1d3r is not clear; however, he points out there is a nod to teenage hacking group Scattered Spider. “Interestingly, the threat actor’s profile picture is taken from an article referencing the threat group Scattered Spider, although it is unclear whether this is to make an intentional association with the threat group.”
