Sonic Corp., the drive-in burger chain known for its rollerskating carhops, is the latest target of hackers seeking consumers’ credit-card accounts.
The company suffered its worst stock decline in almost two months after disclosing a breach of its payment systems. The situation was brought to Sonic’s attention last week by its credit-card processor, which flagged “unusual activity” with cards used at its restaurants.
