Prudential sent a notice to affected customers, which states, “Through the investigation, we learned that the unauthorized third party gained access to our network on February 4, 2024 and removed a small percentage of personal information from our systems.” Prudential said attackers accessed systems containing company administrative and user data, as well as employee and contractor accounts.

Although Prudential says it secured its systems by February 5, ALPHV/BlackCat claimed to retain unauthorized access until at least February 15.

This is the second data breach reported by Prudential in the last year. On July 31, 2023, it sent data breach notices following an attack exploiting the MOVEit file transfer software, which contained a vulnerability that led to attacks against a wide range of organizations that use it. The 2023 incident exposed the Social Security numbers, phone numbers, and addresses of 320,840 people.

Thankfully, this latest breach isn’t as big and didn’t expose information that could directly lead to identity theft or fraud. Still, victims should be on the lookout for phishing emails and messages sent by scammers posing as Prudential or a related company. Never click on attachments or links in unsolicited emails.
