Credit card companies and financial institutions indicate the California Department of Motor Vehicles may have been breached, with MasterCard recently sending an alert memo of a "card-not-present" breach indicating online transactions.
It's unknown how the California DMV was compromised, but stolen information includes credit card numbers, three-digit verification codes, and expiration dates are at risk - and an investigation will try to determine if driver's license numbers, Social Security numbers, phone numbers, and addresses were also at risk.
"We're seeing two percent of our card base compromised as a result of this, and our cards are 100 percent concentrated here in California," said a representative at an undisclosed bank, speaking to Krebs on Security. "That's still a big number, and it's a huge exposure window."
Consumers need to be vigilant in how they handle their own personal information, and follow these types of high-profile security breaches.
