U.S. accelerating cyberweapon research

The Pentagon is accelerating efforts to develop a new generation of cyberweapons capable of disrupting enemy military networks even when those networks are not connected to the Internet, according to current and former U.S. officials.

The possibility of a confrontation with Iran or Syria has highlighted for American military planners the value of cyberweapons that can be used against an enemy whose most important targets, such as air defense systems, do not rely on Internet-based networks. But adapting such cyberweapons can take months or even years of arduous technical work.

When U.S. military planners were looking for ways to disable Libya’s air defense system before NATO’s aerial attacks last year, they discussed using cybertechnology. But the idea was quickly dismissed because no effective option was available, said current and former U.S. officials.

They estimated that crafting a cyberweapon would have taken about a year, including the time needed to assess the target system for vulnerabilities.

“We weren’t ready to do that in Libya,” said a former U.S. official, who spoke on the condition of anonymity because of the sensitivity of the discussions. “We’re not ready to do that now, either.”

Last year, to speed up the development of cyberweapons, as well as defensive technology, then-Deputy Defense Secretary William J. Lynn III and Marine Corps Gen. James Cartwright, then vice chairman of the Joint Chiefs of Staff, placed $500 million over five years into the budget of the Defense Advanced Research Projects Agency, one of the Defense ­Department’s premier research organizations.

The agency also has launched new ­cyber-development initiatives, including a “fast-track” program.

“We need cyber options that can be executed at the speed, scale and pace” of other military weapons, Kaigham J. ­Gabriel, DARPA deputy director, said in testimony last month to Congress.

Pentagon officials, meanwhile, are developing a congressionally mandated strategy for the rapid acquisition of cyberweapons that can keep pace with threats and technology.

Officials are researching cyberweapons that can target “offline” military systems in part by harnessing emerging technology that uses radio signals to insert computer coding into networks remotely.

“To affect a system, you have to have access to it, and we have not perfected the capability of reaching out and accessing a system at will that is not connected to the Internet,” said Joel Harding, an independent consultant who is a former military officer and former director of the Information Operations Institute.

Even if an operator gains access, he said, “unless you already have custom-written code for a system, chances are we don’t have a weapon for that because each system has different software and updates.”

In some cases, as with command-and-control systems, military assets rely on Internet connections, making them theoretically easier to target.

Without that connectivity, an attacker would have to rely on other means — for instance, physically inserting into those systems portable devices such as thumb drives or computer components that have been altered.

But such approaches lack the control and predictability that military commanders desire, experts say.

The amount of disclosed spending by the Pentagon on cybersecurity and cybertechnology — offensive and defensive — is $3.4 billion this year. The U.S. Cyber Command, based at Fort Meade, was created in 2010 and has a budget of $154 million this year.

U.S. officials say that existing cyberweaponry has the potential to disable components of a weapon system, ­although it is not likely to destroy the system.

Cyber tools might be used in conjunction with other tactics and weapons. Cybertechnology might, for example, enable an attack by delaying enemy recognition of it until it is underway.

“It will probably never be just a standalone cyberattack on a network,” said Lt. Gen. Charles R. Davis, commander of the Electronic Systems Center at Hanscom Air Force Base, who buys the tools and software that support the Air Force’s offensive and defensive cyber activities.

Cybertechnology was not a significant factor in military operations 10 years ago, Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, said during an Atlantic Council discussion in December. ­“Cyber is a significant factor today.”

In Iraq, during the 2007 surge of U.S. combat forces, the National Security Agency used cyber tools to muddle the signals of the cellphones and laptop computers that insurgents used to coordinate their strikes, according to previously published reports confirmed by former U.S. officials. U.S. cyber operators used those techniques to deceive the enemy with false information, in some cases leading fighters into an ambush by U.S. troops.

But countering Libya’s air defenses was a different story. The operation arose quickly. Officials had not foreseen the Arab Spring uprising against Libyan strongman Moammar Gaddafi, and no intelligence and engineering work had been done to exploit the vulnerabilities of the Libyan air defense system.

Some experts believe that Israel may have used a cyberweapon to blind Syrian radar before bombing a suspected nuclear facility in September 2007, but several former U.S. officials say that the technique more likely used was conventional electronic warfare or radar jamming using signals emitted from an airplane.

The Stuxnet computer virus that reportedly disabled some 900 centrifuges in an Iranian uranium-enrichment plant in 2009 and 2010 — while it has been dubbed by control-system expert Ralph Langner as the world’s “first digital warhead” — lacked the precision, predictability and control that a military commander would need during combat, experts said.

“If I’m trying to knock down an air defense system, I have to know precisely what’s going to happen and when it will happen,” said a former military official. “It’s a fundamentally different approach than Stuxnet.”

DARPA plans to focus an increasing portion of its cyber research on “offensive capabilities to address military-specific needs,” Gabriel said recently in testimony before the House Armed Services subcommittee on emerging threats and capabilities.

Over the past decade, instances have been reported in which cyber tools were contemplated but not used because of concern they would result in collateral damage. For instance, defense and intelligence agencies discussed using cybertechnology to freeze money in Iraqi dictator Saddam Hussein’s bank accounts just before the U.S.-led invasion in March 2003 to blunt his efforts to mount a defense. The plan was aborted because of concern that the cyberattack could disrupt financial systems in Europe and beyond.

Within a war zone, the use of a cyberweapon may be limited by other considerations. There is the danger of collateral damage to civilian systems, such as disrupting a power supply to a hospital. A destructive computer code, once released, could be reverse-engineered and sent back at vulnerable U.S. targets or adapted for use by foreign spy agencies. Cybertechnology also is not always the most efficient way to attack a target — sometimes bombs or electronic warfare are easier or more reliable.

Within the Pentagon, more money is being spent on defending against cyber­attacks than on preparing to deploy offensive cyber operations, officials say. That is appropriate, they say, when adversaries are trying to develop similar cyberweapons to use against U.S. military targets that may not be secure against attack and when Pentagon networks are probed thousands of times daily.

But more money needs to be spent on developing cyperweapons, say some former officials. “You’ve got to start moving investment to the offensive side,” Cartwright said.

Pentagon spending on cybertechnology is growing even as other areas of its budget are shrinking, officials say.

“I am still not remotely satisfied with where we are in cyber,” Deputy Secretary of Defense Ashton B. Carter said at the Credit Suisse and McAleese and Associates defense conference in Arlington this month.

“I dare say,” he said, “we’d spend a lot more if we could figure out where to spend it.”
