Hackers may have made off with millions of credit card and debit card accounts used at Sonic Drive-In locations, according to a security blog.
In a posting Tuesday, Krebs on Security said Sonic Drive-In, a fast-food chain with 3,600 restaurants in 45 states, has acknowledged a breach affecting an unknown number of Sonic cash registers, known today as point-of-sale terminals.
About 5 million credit card numbers were recently put up for sale on a shadowy underground online network, Krebs wrote. The card has recently been used at Sonic locations.
Unknown at this point is whether the breach affected only a small portion of Sonic Drive-In sites or the entire chain.
The company's credit card processor informed Sonic last week of "unusual activity regarding credit cards used at Sonic," said Christi Woodworth, a Sonic spokeswoman.
"We are working to understand the nature and scope of this issue, as we know how important this is to our guests," a statement by the company said. "We immediately engaged third-party forensic experts and law enforcement when we heard from our processor. While law enforcement limits the information we can share, we will communicate additional information as we are able."

This is probably the biggest disadvantage credit/debit cards have in comparison to bitcoin.
2nd biggest disadvantage for credit cards are APR rates, of which crypto typically has none.
There are some who dislike bitcoin's transfer rates but over the long term transfer rates could be the price crypto users pay to avoid having millions of accounts breached and sold over the internet like credit/debit card users routinely do.
