In the past few days, fleet managers trying to access information about vehicle recalls on the National Highway Traffic Safety Administration’s website may have become frustrated. Documents normally available to the public have been inaccessible. As it turns out, hackers are to blame, the New York Times reported. 

Ten NHTSA servers used to store documents on vehicle recalls and safety investigations were hacked into late last week, triggering a “cybersecurity incident” alert from the United States Computer Emergency Readiness Team, the newspaper reported. This led to the temporary shutdown of public access to the recall documents because the servers involved were disconnected from the Internet.

In an e-mailed statement to the newspaper, NHTSA said the hacking incident was limited in scope and only involved systems that host publicly available information. No confidential information was compromised.

The agency added it is working to resolve the issue as soon as possible so that the documents are again accessible.
