Sonic Corporation (NASDAQ:SONC) just revealed some bad news for customers. A Sonic data breach has affected millions of credit and debit cards.
The Sonic data breach has resulted in some 5 million credit and debit cards being sold online. The cards are up for sale on a Joker’s Stash that specifically deals in stolen cards. This batch of stolen information went live on the website on Sept. 15.
SONC says that it is ware of the matter and is conducting an investigation. However, it notes that this is still only in its early phase. As a result of the Sonic data breach, the company has also reached out to forensic experts and law enforcement.
“Our credit card processor informed us last week of unusual activity regarding credit cards used at Sonic,” the company told KerbsonSecurity. “While law enforcement limits the information we can share, we will communicate additional information as we are able.”
KerbsonSecurity noticed the Sonic data breach after being informed by unnamed sources of fraud purchases on credit and debit cards recently used at the fast food chain. It then confirmed that the cards being sold on Joker’s Stash have all recently been used at Sonic locations recently.
The Sonic data breach isn’t the only one to happen recently. Another major one happened at Equifax Inc. (NYSE:EFX) that saw 143 million people have their private information stolen. The CEO of EFX recently announced his retirement in connection to the data hack.
There’s also been a Deloitte data hack that resulted in the private emails of some customers being stolen. The U.S. Securities and Exchange Commission revealed that it too has been the target of hackers recently.
SONC stock was down 2% as of Wednesday morning.
As of this writing, William White did not hold a position in any of the aforementioned securities.
