Data Breaches HackerOne Employee Data Exposed in Massive Navia Breach The cybersecurity firm said the personal information of hundreds of employees was stolen in the hacker attack targeting Navia. By Eduard Kovacs | March 25, 2026 (3:57 AM ET) Flipboard Reddit Whatsapp Whatsapp Email Cybersecurity firm HackerOne is notifying nearly 300 employees that their personal information was exposed in a data breach recently disclosed by third-party benefits administrator Navia Benefit Solutions. Navia revealed last week that it discovered unauthorized access to its systems on January 23, and an investigation found that the attacker had access between December 22, 2025, and January 15, 2026. The company said the hackers accessed and acquired information such as names, dates of birth, Social Security numbers, phone numbers, email addresses, and health plan information. Navia told the Maine Attorney General’s Office that nearly 2.7 million individuals are impacted by the data breach. In a notification submitted this week to the Maine AGO, bug bounty platform and offensive security solutions provider HackerOne said it was recently notified by Navia, which serves as one of its US benefits administrators, that the information of 287 employees may have been affected by the data breach. HackerOne said the notification it received from Navia was dated February 20, but it was only delivered in March. Advertisement.

If we are not satisfied, we will explore other potential options for benefits providers with our broker.” Navia said in its notification to impacted individuals that it’s not aware of “any attempted or actual misuse” of the exposed information. However, ‘no evidence of misuse’ is a standard disclaimer frequently issued by breached companies. In Navia’s case there is no indication that cybercriminals have made public any data stolen from the company’s systems, but the aforementioned disclaimer has been used in the past even by firms that had their data publicly leaked.
