A Burger, an Order of Fries, and Your Credit Card Number
Why it’s so easy for hackers to steal financial information from restaurants.

At some point in your restaurant-going life, you’ve probably felt a pang of doubt when you handed over your Visa card. How easy it would be, you probably thought, for a waiter to copy your credit card number and head out on a shopping spree. You probably got over it, reasoning that people who do such things probably get caught. And maybe you’re right. But that doesn’t mean you’re safe. The real threat isn’t that your charming waiter will steal your financial information. It’s that the Russian mafia will steal it from your waiter.
On Thursday, Verizon released its Data Breach Investigations Report, an annual landmark in the data-security industry. The big story this year, Verizon reports, was the rise of “hacktivists”—vigilantes who orchestrate high-profile cyber-attacks on big corporations, government entities, and even Internet security companies, usually to make a political statement (although sometimes, it seems, out of sheer vindictiveness). These are the attacks that make headlines, and for good reason: They’re sophisticated, brazen, and sometimes downright scary.
But if 2011 was “the year of the hacktivist,” as Forbes proclaimed, every year is the year of the run-of-the-mill cybercriminal. For at least a decade, organized crime groups around the world, but particularly in Eastern Europe, have been honing their hacking skills in a bid to capture our credit card and bank account numbers. Increasingly, they’re targeting restaurant franchises and other small businesses by hacking their point-of-sale checkout systems, which are often woefully insecure. And, as the Verizon report shows, they’re getting better at it all the time.
Unlike hacktivists’ flashy attacks, these criminals’ exploits rarely make the news. Publicity is not in their interest, and it can takes months for their victims to find out they’ve been hit. When businesses do learn they’ve been compromised, they often conclude that publicizing the crimes wouldn’t be in their interest either. For these reasons, attacks on retail establishments fly under the radar, though they vastly outnumber those orchestrated by well-known groups like Anonymous and LulzSec, which accounted for just 3 percent of the 855 data-breach cases covered in the Verizon report.
Restaurants were easily the most-targeted businesses, accounting for over half of all reported attacks. Retail stores were second, at about 20 percent. The findings are consistent with those of a similar report released earlier this year by Trustwave, an information security company, which found that the food and beverage, retail, and hospitality industries combine to account for 80 percent of data breaches.
Why are small businesses such frequent targets? Because they offer hackers the easiest path to your financial information. In fact, security consultants say, there’s an entire underground industry built around extracting customers’ credit card numbers from retailers’ point-of-sale systems.
Rich Mogull, an information security analyst who runs a company called Securosis, explains that a typical cybercrime works something like this. First, a hacker—often in Russia, but sometimes in the United States, Romania, Vietnam, or elsewhere—uses special software to scan a portion of the Internet for IP addresses that look like they might belong to the servers restaurants and retailers use to transmit credit and debit card data. When they find them, they send that information to another program that starts trying common passwords to log into the server remotely.
