Bloomberg Businessweek reports: In October 2010, a Federal Bureau of Investigation system monitoring U.S. Internet traffic picked up an alert. The signal was coming from Nasdaq. It looked like malware had snuck into the company’s central servers. There were indications that the intruder was not a kid somewhere, but the intelligence agency of another country. More troubling still: When the U.S. experts got a better look at the malware, they realized it was attack code, designed to cause damage.
As much as hacking has become a daily irritant, much more of it crosses watch-center monitors out of sight from the public. The Chinese, the French, the Israelis — and many less well known or understood players — all hack in one way or another. They steal missile plans, chemical formulas, power-plant pipeline schematics, and economic data. That’s espionage; attack code is a military strike. There are only a few recorded deployments, the most famous being the Stuxnet worm. Widely believed to be a joint project of the U.S. and Israel, Stuxnet temporarily disabled Iran’s uranium-processing facility at Natanz in 2010. It switched off safety mechanisms, causing the centrifuges at the heart of a refinery to spin out of control. Two years later, Iran destroyed two-thirds of Saudi Aramco’s computer network with a relatively unsophisticated but fast-spreading “wiper” virus. One veteran U.S. official says that when it came to a digital weapon planted in a critical system inside the U.S., he’s seen it only once — in Nasdaq.
The October alert prompted the involvement of the National Security Agency, and just into 2011, the NSA concluded there was a significant danger. A crisis action team convened via secure videoconference in a briefing room in an 11-story office building in the Washington suburbs. Besides a fondue restaurant and a CrossFit gym, the building is home to the National Cybersecurity and Communications Integration Center (NCCIC), whose mission is to spot and coordinate the government’s response to digital attacks on the U.S. They reviewed the FBI data and additional information from the NSA, and quickly concluded they needed to escalate.
Thus began a frenzied five-month investigation that would test the cyber-response capabilities of the U.S. and directly involve the president. Intelligence and law enforcement agencies, under pressure to decipher a complex hack, struggled to provide an even moderately clear picture to policymakers. After months of work, there were still basic disagreements in different parts of government over who was behind the incident and why. “We’ve seen a nation-state gain access to at least one of our stock exchanges, I’ll put it that way, and it’s not crystal clear what their final objective is,” says House Intelligence Committee Chairman Mike Rogers, a Republican from Michigan, who agreed to talk about the incident only in general terms because the details remain classified. “The bad news of that equation is, I’m not sure you will really know until that final trigger is pulled. And you never want to get to that.”
Bloomberg Businessweek spent several months interviewing more than two dozen people about the Nasdaq attack and its aftermath, which has never been fully reported. Nine of those people were directly involved in the investigation and national security deliberations; none were authorized to speak on the record. “The investigation into the Nasdaq intrusion is an ongoing matter,” says FBI New York Assistant Director in Charge George Venizelos. “Like all cyber cases, it’s complex and involves evidence and facts that evolve over time.”
While the hack was successfully disrupted, it revealed how vulnerable financial exchanges—as well as banks, chemical refineries, water plants, and electric utilities—are to digital assault. One official who experienced the event firsthand says he thought the attack would change everything, that it would force the U.S. to get serious about preparing for a new era of conflict by computer. He was wrong. [Continue reading…]
