Electronic security a worry in an age of digital espionage

The growing reach of the Internet and the proliferation of smartphones have made it easier to steal information remotely

When Kenneth Lieberthal, a China expert at the Brookings Institution, travels to that country, he follows a routine that seems straight from a spy film.

He leaves his cellphone and laptop at home and instead brings “loaner” devices, which he erases before he leaves the US and wipes clean the minute he returns. In China, he disables Bluetooth and Wi-Fi, never lets his phone out of his sight and, in meetings, not only turns off his phone but also removes the battery, for fear his microphone could be turned on remotely. He connects to the Internet only through an encrypted, password-protected channel, and copies and pastes his password from a USB thumb drive. He never types in a password directly, because, he said, “the Chinese are very good at installing key-logging software on your laptop.”

What might have once sounded like the behavior of a paranoid is now standard operating procedure for officials at US government agencies, research groups and companies that do business in China and Russia — like Google, the State Department and the Internet security giant McAfee. Digital espionage in these countries, security experts say, is a real and growing threat — whether in pursuit of confidential government information or corporate trade secrets.

“If a company has significant intellectual property that the Chinese and Russians are interested in, and you go over there with mobile devices, your devices will get penetrated,” said Joel Brenner, formerly the top counterintelligence official in the office of the director of national intelligence.

Theft of trade secrets was long the work of insiders — corporate moles or disgruntled employees. But it has become easier to steal information remotely because of the Internet, the proliferation of smartphones and the inclination of employees to plug their personal devices into workplace networks and cart proprietary information around. Hackers’ preferred modus operandi, security experts say, is to break into employees’ portable devices and leapfrog into employers’ networks — stealing secrets while leaving nary a trace.

Targets of hack attacks are reluctant to discuss them and statistics are scarce. Most breaches go unreported, security experts say, because corporate victims fear what disclosure might mean for their stock price, or because those affected never knew they were hacked in the first place.

But the scope of the problem is illustrated by an incident at the US Chamber of Commerce in 2010.

The chamber did not learn that it — and its member organizations — were the victims of a months-long cybertheft until the FBI told the group that servers in China were stealing information from four of its Asia policy experts, who frequent China. By the time the chamber secured its network, hackers had pilfered at least six weeks worth of e-mails with its member organizations, which include most of the nation’s largest corporations. Later still, the chamber discovered that its office printer and even a thermostat in one of its corporate apartments were still communicating with an Internet address in China.

The chamber did not disclose how hackers had infiltrated its systems, but its first step after the attack was to bar employees from taking devices with them “to certain countries,” notably China, a spokesman said.

The implication, said Jacob Olcott, a cybersecurity expert at Good Harbor Consulting, was that devices brought into China were hacked. “Everybody knows that if you are doing business in China, in the 21st century, you don’t bring anything with you. That’s ‘Business 101’ — at least it should be.”
