Is US cyber defense a key weapon against N. Korea’s missile program?

March 9, 2017

DW:

Amid rising tensions on the Korean peninsula, a recent report indicates that the US has successfully used cyber attacks to disrupt North Korean missile tests, opening a new “invisible front” against the bellicose state.

There is currently a big show of force happening in Northeast Asia.  On March 7, for the second time in a month, North Korea fired missiles into the Sea of Japan, rattling both the nerves of its neighbors and their allies in the West. Pyongyang raised tensions further by adding that the recent launch was a drill for attacking US military bases in Japan.

It came just a day after the US moved a missile defense system known as Terminal High Altitude Area Defense (THAAD) into positions in South Korea. And last week, the US and South Korean militaries began what is being described as “the largest ever” military drill between the two countries.

China’s Foreign Minister Wang Yi said on Wednesday that both sides were racing towards a “head-on collision.”

But behind this very public display of hostility is a complex system of information technology – a less visible but crucial strategic element that defense departments and experts are increasingly viewing as the future of warfare.

And an investigative report published on March 4 in the New York Times indicates that the US, under former President Barack Obama, indeed used cyber attacks in an attempt to disrupt North Korean missile tests.

The report came after an eight-month investigation into US Defense Department records and missile defense documents. The curiosity of journalists David Sanger and William Broad was sparked after they noticed that North Korea’s medium-range missiles – called “Musudan” – tested during 2015-16 were exploding and veering off course and had a failure rate of 88 percent.

If US cyber attacks contributed to, or were the reason behind these missile failures, it would be a key success for the US in conducting a new type of warfare. However, it is very difficult to independently verify the causal link between US cyber attacks and defective missiles.

“We’ll never know for sure, because North Korean missiles crash on their own without any outside help,” James Lewis, a leading expert on international cyber security at the Center for Strategic and International Studies (CSIS) and a contributor to the North Korea think tank 38 North, told DW.

“On the other hand, some say the military officers recently executed by Kim Jong Un were killed because they had failed to block the missile hacks.”

The invisible war

Regardless of whether the US bugged North Korean missiles, cyber warfare clearly seems to be on the US military’s strategic agenda and Washington certainly has the technological capacity to implement cyber attacks.

The Cyber Deterrence Defense Report, released by the Defense Science Board at the US Department of Defense in February, issued recommendations that would “increase US confidence and adversary uncertainty” in areas of cyber defense.

Among specific recommendations in the report, “select cyber offence” and “select long-range conventional strikes” were identified as priorities in coming up with a strategic cyber defense policy.

Whether these capabilities can actually be expanded to continually disrupt North Korea’s missile program remains to be seen and this uncertainty highlights the sensitivity and vulnerability of cyber weapons.

“One you use it, it’s gone,” said Lewis. “If it was still a secret, it would have been effective.  Now we’ll need to do something else,” he noted, adding that he doubted the Trump administration would seek to expand cyber attacks on North Korean missiles. “Cyber capabilities will continue to grow, as it’s important for any advanced military to have cyber capabilities, but the rabbit is out of the hat on this one.”

Riki Ellison, Chairman of the Missile Defense Advocacy Alliance (MDAA), a US-based defense advisory nonprofit, told DW that the new US administration would implement cyber weapons to disrupt supply chains in missile production, but added that effective capabilities would only become apparent if the weapon is activated.

“Once you expose your cyber capability in the network, you no longer are effective,” said Ellison.

And the most likely US cyber adversaries, China and Russia, will surely be paying attention to the effectiveness of US cyber deployment. If it becomes clear that the US is successfully using cyber weapons to disrupt conventional defense systems, it could trigger a cyber arms race.

“Both [China and Russia] are very worried about the US hacking their weapons systems,” said Lewis. “Their answer will be to try to make their networks more secure, and speaking as a former UN negotiator, they are not interested in ‘arms control.’ It’s a new battlefront in an invisible war.”

The level of technical sophistication required to have caused the North Korean missiles to explode or veer off course would be a clear indication that the US either could have somehow introduced malware into the design of the Musudan missiles or was able to remotely disrupt its launch systems.  Either would be a major advancement in the use of cyber warfare.

North Korean retaliation?

For North Korea to retaliate against weapons systems hacking, they would first need to recognize the intrusion. According to Ellsion from the MDAA, even with Chinese support in evading cyber attacks on critical systems in weapon supply chains, North Korea would find it difficult to identify a cyber attack on its missile systems. “North Korea’s systems are antiquated, old, and a lot are not on the network,” he said….
