Millions Of Credit Card Numbers May Have Been Stolen In Sonic Drive-In Breach

It’s a day of the week ending in “y,” which can only mean one thing: Another national company’s payment system has been compromised. This time, it’s the Sonic Drive-In fast food chain, where potentially millions of credit card numbers may have been stolen. KrebsOnSecurity.com confirmed the breach with Sonic earlier today, after recently coming across a for-sale stash of around 5 million stolen credit card numbers.
