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. According to Krebs, a common link for some of these purloined credit card numbers was that they had recently been used to make purchases at Sonic.
