The US Department of Transportation (USDOT) has revealed that threat actors breached its system during a cyberattack. The data breach compromised the personal information of roughly 237,000 current and former agency employees.

USDOT made the announcement just a few days before the Government Accountability Office (GAO) issued a report on cybersecurity. The report stated that USDOT should improve the implementation of its cybersecurity policies.

Researchers says, the attack hit systems for processing TRANServe transit benefits. For now, the incident affected the process that returns commuting costs to government employees.


The ongoing investigation of the attack limited the breach to some of the systems that were used for administrative tasks. As a security measure, while the investigation is still ongoing, the specialists momentarily froze access to the transit benefit system.

USDOT also stated that apparently, the data breach had no impact on the transportation safety systems. However, the breach affected 114,000 current and 123,000 former USDOT employees.
