Sonic Drive-In customers beware: 5 million credit card numbers stolen
OKLAHOMA CITY — Sonic Drive-In is the latest company to be affected by a credit card security breach.
The website KrebsOnSecurity.com reported the breach involved the theft of 5 million credit and debit card numbers used at Sonic's 3,600 locations nationwide, numbers that were then sold on the black market to be used fraudulently.
In a statement, Sonic told the website that its credit card processor detected "unusual activity" involving cards used at Sonic. The chain is working with third-party forensic experts and law enforcement to investigate the breach further.
The company has not issued a statement about the breach on its website or social media as of Wednesday morning.
Sonic has 17 locations throughout New Jersey.
Fellow chain Chipotle suffered a breach last spring with "irregular credit card transactions."
Earlier this month, credit monitoring company Equifax announced a high-tech breach that exposed Social Security numbers and other sensitive information about 143 million Americans.
