Thousands of restaurant customers are nervously watching their credit card accounts after a major data breach that may have targeted hundreds of popular U.S. restaurants.
All have dined in recent months at restaurants owned by Houston-based Landry's Inc., which oversees 37 locations under different names in Southern California.
Possibly impacted establishments include popular chains like Claim Jumper, Morton's Steakhouse, Bubba Gump Shrimp Company, Chart House, Mastro's, The Rusty Pelican, and McCormick & Schmick.
In a statement sent to the I-Team, Landry’s says it “recently received reports of unauthorized charges on certain payment cards after the cards were used legitimately at some of its restaurants."

"It's new-age goldmining," he said. "It's a treasure trove of data. when they hit the jackpot, they can use them over and over again. That's why it's so attractive."
The I-Team reached out to Landry's to find out if the restaurants have switched over to the new credit card “chip,” or EMV, system, which is supposed to prevent this kind of fraud.

Landry's hasn't identified the specific restaurants involved with the breach or exactly when the hack took place, but the company is urging customers of all its establishments to monitor their credit card accounts and report any suspicious activity to their bank right away.
