Police say someone may have breached the credit card processing services at the California Department of Motor Vehicles, according to the DMV’s website.
The state DMV advised anyone who has renewed their driver’s license in California using a credit card to keep a close eye on their statements for unusual activity. It said there is no evidence of a direct breach of the DMV’s computer system, and said it would closely monitor all website traffic and credit card transactions.
“Out of an abundance of caution and in the interest of protecting the sensitive information of California drivers, the DMV has opened an investigation into any potential security breach in conjunction with state and federal law enforcement,” a post on the DMV site reads.
According to the Los Angeles Times, the breach may cover transactions made between Aug. 2, 2013, and Jan. 31, 2014. It wasn’t clear how many customers might have been affected.
