Sonic Corp. [NASDAQ: SONC]

Federman & Sherwood Investigates Sonic Corp. for Data Breach

The law firm of Federman & Sherwood announced the filing of the first data breach lawsuit against Sonic Corp. [NASDAQ: SONC], arising from the data breach announced by Sonic Corp. on September 27, 2017. The lawsuit was filed in the United States District Court for the Western District of Oklahoma. Sonic is a fast food chain with nearly 3,600 locations across 45 U.S. states. Sonic has acknowledged a breach affecting an unknown number of store payment systems which may have subsequently led to the sale of millions of stolen credit and debit card accounts that are now being peddled in shadowy underground cybercrime stores. Sonic announced that it was investigating the data breach but that it does not yet know the number of stores or customers impacted by the breach.
