Plum Island, N.Y. – The squad of grid operators had spent days restoring ability when a digital smasher took out i of ii operational utility stations. The other utility was also nether attack. A calendar month had passed since all ability inward the part was taken downward past times a devastating cyberattack. It had been a grueling 6 days restoring ability across ii electrical utilities too to the edifice deemed a critical national property past times the Secretary of Energy.
The cyber smasher hadn’t forced the squad dorsum to zero, but it wasn’t far from it.
Just moments ago, the ii electrical utilities had been working inward concert, delivering reliable too redundant ability to the critical asset. Now i utility was downward for the count too the other was nether attack.
The grid operators’ solely take away chances to restore ability to the property would last to route it, substation past times substation, from the utility that was silent operating. The squad of cybersecurity researchers assisting the grid operators would take away hold to utilization every slice of technology too know-how they had to ensure that utility stayed powered up, trustworthy too malware-free.
The Defense Advanced Research Projects Agency exercise, which took house from Nov. 1 to Nov. 7, was fictional, but it was designed to mimic all the hurdles too dubiety of a real-world cyberattack that took out ability across the field for weeks on end–a scenario known equally a “black start.”
To add together realism, the practice took house on Plum Island, a federal enquiry facility off the due north fork of Long Island, where DARPA researchers were able to segregate a part of the isle on its ain electrical grid.
Over the course of education of the seven-day exercise, to a greater extent than than 100 people gathered on the island, filling every necessary role to mimic an actual dark start.
At the middle of the practice was a squad of grid operators from electrical utilities across the nation, which was inward accuse of restoring too sustaining power.
At its most basic level, their task involved creating initial ability transmissions at both utilities using a diesel fuel generator, therefore edifice cyber-secure “crank paths” through a serial of electrical substations that would increase the transmissions’ voltage until they were capable of powering the ii utilities too delivering redundant ability to the exercise’s critical asset.
Meanwhile, to a greater extent than or less other squad of DARPA-funded cyber researchers from 7 dissimilar manufacture groups used custom built technology to maintain the grid operators’ efforts protected from cyber adversaries.
A tertiary DARPA-funded squad took the role of the cyber adversaries, throwing a wrench into the goodness guys’ efforts every fourth dimension they seemed to last getting ahead.
“We take away hold a bunch of things that essay to brand this equally painful equally possible for everyone,” projection leader Walter Weiss told reporters on a rainy Tuesday, the 6th twenty-four hr menstruation of the exercise. “How create yous really maintain the smartest people inward the basis busy for a week? That takes effort.”
Try, Try Again
The Plum Island practice is the 4th dark start practice led past times DARPA’s Rapid Attack Detection, Isolation too Characterization Systems, or RADICS, program, which Weiss leads. The foremost ii exercises were conducted inward enquiry labs. The tertiary i took house on Plum Island but on a smaller scale too without world observers.
DARPA plans to spill out the exercises every 6 months until the RADICS computer programme expires inward 2020, Weiss said. After that, hopefully, the projection volition spill out nether the Energy Department or to a greater extent than or less other federal agency, he said.

The RADICS practice doubled equally the 2nd stage of an Energy Department practice called Liberty Eclipse. The foremost stage of that exercise, which took house inward October, was a tabletop practice during which regime too manufacture officials game planned policy options later a massive cyberattack against the grid.
That practice ended alongside the fictional president declaring a grid emergency too the unloosen energy secretarial assistant using a power foremost formalized before this twelvemonth to number emergency orders to instruct the grid dorsum upwards too running.
One of those orders—to instruct redundant ability to the critical property on Plum Island—marked the showtime of the on-island practice this month.
While Weiss too projection organizers pushed for realism inward the exercise, they kept to a greater extent than or less details vague. The utilities were dubbed merely Utility H5N1 too Utility B. The scenario doesn’t advert the the U.S.A. adversary that launched the grid-crippling cyberattack. Nor does it position the “critical asset” that grid operators must maintain running.
In a real-world attack, that critical property powerfulness last a hospital, a armed forces base of operations or whatever other edifice that’s critical for the nation’s functioning during an emergency.
In the exercise, the property was an aged brick edifice outfitted, on an upper level, alongside 5 multi-colored air dancers—the colorful, fan-powered, headbanging nylon tubes that frequently adorn car dealerships too cellular telephone stores.
Weiss described the air dancers equally “high visibility ability indicators.” When the property was receiving power, the dancers would create their affair too the grid operators, observing from a distance, could breathe easy. If the dancers started slouching, they knew something was wrong.
A Very Particular Set of Tools
The cyber researchers, who hailed from the National Rural Electric Cooperative Association, BAE Systems, Perspecta Labs too elsewhere, brought iii main types of technology to the DARPA exercise:
Tools that render situational awareness virtually what portions of the grid cyberattackers had infected alongside malware too which parts remained secure.
Tools that isolated salubrious parts of the grid therefore they couldn’t last infected.
Tools that assessed too diagnosed the nature of the cyberattack that brought the grid down.

The researchers' primary focus was testing, communicating virtually too bypassing infected parts of the ability grid without creating whatever digital connections that could send malware infections into the tools themselves or into post-attack portions of the grid.
Their situational awareness tools, for example, ignored digital signals from the grid too relied on basics physics tests that are impossible to hack. Their cellphones too other communications systems operated on local networks that were segregated from the network too broader telecom networks.
The destination wasn’t for the tools to compete against each other, Weiss said, but to essay how effectively researchers too grid operators could utilization the tools later a genuinely devastating cyberattack.
In to a greater extent than or less cases, the tools didn’t perform equally planned. In other cases, they worked well, but didn’t render data inward a format that was most useful to grid operators, Weiss said. That’s feedback the teams tin utilization to rejigger their tools for the adjacent practice inward 6 months, he said.
In other cases, the tools worked but were stymied past times other factors that powerfulness also touching on a real-world grid attack.
Researchers readied a conditions balloon, for example, that could wing 500 feet inward a higher house the isle too uncovering acoustic hum too other indicators of where electricity was too wasn’t flowing properly. When reporters visited on the 6th twenty-four hr menstruation of the exercise, however, the balloon was grounded past times persistent rain.
Earlier inward the exercise, researchers spent an entire twenty-four hr menstruation chasing what they believed was a ruby-red squad cyberattack but was really precisely an anomaly inward grid operations, Weiss said.
“It was precisely a giant simulated positive for a day,” he said. “If yous accept a bunch of researchers too stick them on an isle similar this, they’re going to instruct pretty paranoid.”

Finally, many times the tools worked effectively but needed the researchers, who were based inward nearby Orient Point, Long Island, to become out too tinker alongside them or to aid the grid operators troubleshoot, Weiss said.
In the exercise, that meant a delay of an hr or ii piece researchers waited for the adjacent ferry to the isle too made their way to the utility or substation. In a real-world dark start, however, that could hateful a hold off of days or to a greater extent than piece a too-small cadre of harried cyber experts zipped from house to place.
Weiss’s challenge for the cyber researchers, he said, is that their tools should last therefore user-friendly past times the terminal practice inward 2020 that grid operators—or anyone else without specialized cyber training—will last able to utilization them to re-establish ability past times merely reading a manual.
In a real-world grid attack, for example, National Guard units powerfulness last deployed to re-establish ability to specific assets or to restart ability inward specific sectors, Weiss said.
And There Was Light
By the cease of the 7th day, despite ongoing ransomware too other cyberattacks too the loss of ability at Utility B, grid operators were able to re-establish ability at the critical asset, Weiss told Nextgov inward an e-mail later the exercise.
DARPA’s main enquiry focus for the practice wasn’t the grid operators’ success or failure, however, but how good the tools withstood diverse impediments too assaults past times the ruby-red squad of cyberattackers, Weiss said.
If the grid operators too cyber researchers were over-performing, the ruby-red squad would automatically throw something to a greater extent than hard at them, Weiss said. That meant the grid operators were nearly foreordained to come across their destination past times a whisker’s margin.
The ruby-red squad socked away virtually 10 days of mischief for the seven-day exercise, Weiss said, therefore it could jibe the grid operators’ too researchers’ best piece of job too silent take away hold something left over for the adjacent practice inward 6 months.

“Our destination is to last dynamic,” he said. “We don’t desire them to last perfect. We desire to uncovering the limits of the tools. We’re driving them to a indicate where nosotros view how far they tin instruct too therefore nosotros shell them dorsum down.”
That may audio sadistic, but it mirrors what grid operators too their cyber helpers are probable to confront inward a real-world massive onset past times a the U.S.A. adversary.
“If yous await at advanced persistent threats, they instruct to a greater extent than tools, they don’t instruct less,” Weiss said, using a mutual phrase for highly skilled nation-state-backed hacking teams from Russia, China, Islamic Republic of Iran too elsewhere.
If the tools tin withstand that assort of battering, Weiss said that agency they tin last useful inward less extreme situations.
“We practice alongside that absolute worst-case scenario where everything’s gone wrong, everything’s failed for a calendar month too enquire how are our tools silent relevant,” Weiss said. “If nosotros tin bear witness a tool plant when everything else is broken, that gives us to a greater extent than confidence.”
