Oct 4 (Reuters) - Fast-food chain operator Sonic Corp said on Wednesday a malware attack at some of its drive-in outlets may have allowed hackers to access customers’ debit and credit card information.
Cybersecurity blog KrebsOnSecurity first reported the news last week and added that the activity may have led to millions of stolen credit and debit card numbers being sold in underground exchanges. (bit.ly/2xve25F)
Sonic said it would offer free identity theft protection for affected customers, in wake of the breach.
