The largest leak of driver's license numbers in 2026 hit a US insurance company

A cyberattack on one of the large US insurance companies has resulted in the largest leak of driver's license numbers seen so far in 2026.

According to available data, the attackers managed to gain access to the personal data of millions of the insurer's customers, including driver's license numbers.

The scale of the incident

The attack hit an insurance company described in the report as an industry “giant,” which points to a significant volume of compromised data. The exact number of affected users, as well as details of how the attackers gained access to the company's systems, have not yet been disclosed.

Context

Leaks of data tied to driver's licenses pose a particular danger, since such documents are often used to verify identity in a variety of transactions — from renting a car to opening bank accounts. Having this data fall into the hands of attackers raises the risk of fraud and identity theft for those affected.

The incident is yet another reminder that companies handling large volumes of personal data continue to be an attractive target for cyberattacks. According to the source, this is the largest known case of a driver's license number leak since the start of 2026, which underscores the growing scale of such incidents in the insurance industry.

Further details about the nature of the attack, the range of those affected, and the company's response measures have not yet been reported.
