Fidelity National Financial (FNF), a Fortune 500 insurance company, has officially acknowledged falling victim to a cybersecurity incident, as reported in an 8-K filing with the Securities and Exchange Commission (SEC). The company disclosed the forced shutdown of several systems, affecting key services related to title insurance, escrow, mortgage transactions, and technology for the real estate and mortgage industries.
With over $11 billion in total revenue in 2022, FNF is a major underwriter of title insurance and transaction services provider in the US real estate and mortgage sectors. The company reported that an intruder accessed certain systems and acquired credentials, prompting the ongoing assessment of the incident’s impact on operations.
The 8-K filing, dated November 19 and made public two days later, revealed that FNF became aware of the incident over the weekend. Ransomware group ALPHV/BlackCat claimed responsibility for the attack on November 22, withholding specific details about the accessed data. FNF is actively working to restore normal operations while assessing the incident’s potential material impact on the company.
Security experts speculate that the entry point into FNF systems may be linked to the exploitation of a critical vulnerability affecting Citrix Netscaler devices, known as “CitrixBleed.” Despite applying the patch two weeks after its availability, FNF is grappling with disruptions, impacting companies and home buyers in the US.
ALPHV/BlackCat criticized incident response specialist Mandiant’s actions and reputation in a leak blog post, stating that they would disclose additional information about the attack after allowing FNF more time to respond. The incident’s potential connection to the CitrixBleed vulnerability, which has been exploited by various ransomware groups, raises concerns about the widespread impact and severity of the security breach.
