2016 Most Dangerous Emerging Risks

Cyber Grid Attack: A Cascading Impact

The aggregated impact of a cyber attack on the U.S. power grid could cause huge economic losses and upheaval. 
By: | April 4, 2016 • 8 min read

SCENARIO: The hackers used a range of tactics to gain access to the U.S. electric grid system without alerting security teams — targeting laptops and personal electronic devices of key personnel, conducting phishing attacks, hacking remote access systems and physically intruding on network monitoring locations.

Months later, they systematically disabled safety systems that would prevent power generators from being desynchronized. They sent control signals to open and close the generator’s rotating circuit breakers in quick succession.

This used the inertia of the generator itself to force out of sync the bearings of 50 generators. They had hoped to destroy 100.

The generators began to smoke and burn. Some were partially destroyed. One gas turbine facility exploded from the generator fire. Operators shut down even the uncontaminated generators until the cause of the damage was determined.

The cascading impact of the cyber attack stuns the nation. Engineers have no definitive explanation for the damage, which plunges 15 Northeastern states and Washington, D.C. into darkness, leaving 93 million people without power.

Back-up generators at hospitals, public facilities and some companies remain available for essential services. Phones, internet, ATMs, street lights, subway cars, gas stations, water systems, manufacturers, and just about everything else goes down. Communications systems are mostly unavailable, except for 911.

No one immediately knows the scope of the infection. Or whether it will reoccur.

ANALYSIS: This “Business Blackout” scenario by the University of Cambridge Centre for Risk Studies and Lloyd’s of London suggests a range of $61 billion to $223 billion in economic losses, depending on the number of impacted generators and whether it took two, three or four weeks to restore 90 percent of the power.

“This is a real risk management issue facing the power sector around the world right now,” said Nick Beecroft, emerging risks and research manager, Lloyd’s of London, who worked on the “Business Blackout” project.

But even more, he said, it is a risk that “all of society has to confront as more and more of our infrastructure and economy become connected to digital networks.”

Such an attack “would disrupt businesses spanning the entire economy.” In the scenario, it takes several months and up to three years for the economy to fully revert to the GDP levels prior to the attack.

One insurance executive who asked to remain anonymous said it’s impossible to calculate the cascading impact of a cyber attack on the power grid.

“The honest answer is we don’t know,” the executive said. “It’s difficult to say if this is a one-in-100-year event or a one-in-10-year event. How do we know it won’t happen tomorrow or twice in a week? That’s the scary part for us.”

In 2003, overgrown tree limbs short-circuited sagging transmission lines amid hot weather in Ohio that had already strained generating capacity. Combined with human error, the result was a blackout of eight states and part of Canada for 36 hours, affecting 50 million people.

“I think that shows how interconnected the power grid is,” said Jamie Bouloux, president, cyber practice, Ryan Specialty.

Utilities Are “Under Constant Attack”

Recently, North Korea was accused of hacking a nuclear operator in South Korea; Russia was accused of shutting down Ukraine’s power grid for up to six hours in a sophisticated cyber attack that left up to 230,000 residents in the dark; and Israel’s electric authority successfully fought off a hacking attempt.

“The utilities, energy and infrastructure industries — petroleum, gas, electric power, nuclear, renewable, telecoms, water and sewage — are under constant attack,” said Kevin Kalinich, national cyber leader, Aon Risk Solutions.

The “poster child” for sophisticated nation-state hacks is Stuxnet, where unnamed hackers generally believed to be the United States and Israel introduced malware into Iran’s industrial control systems, causing nuclear centrifuges to spin out of control and damage themselves even while displays indicated normal functioning.

The controllers used in Iran are the same as those used in U.S. military systems, power plants, water systems, transportation, manufacturing and other commercial and industrial enterprises, said cyber security expert Joe Weiss, managing director of Applied Control Solutions.

“There are only 10 to 15 vendors [of control systems] worldwide and they supply every industry.”

And they are vulnerable, he said.

“It is possible to compromise the power grid via a cyber attack. Depending on the attack, it is possible to bring the grid down for nine to 18 months. This is existential to the United States.

“Nation-states are actively targeting our critical infrastructure and actively trying to compromise control systems,” Weiss said. “We know that.

“Not much is being done and the cyber insurance world needs to understand the cyber risks to these critical control systems.”

Security Has Increased

Utilities have been working to better secure infrastructure, including the grid and their distribution and transmission networks, said Gary Gresham, senior vice president, power practice, Aon Global Power.

In 2012, $14 billion was spent to shore up grid reliability and redundancy. That’s compared to about $5 billion spent in 2003.

But the utility industry is more advanced in protecting their systems and sharing information than other sectors of the country, including transportation, communications, industrial and manufacturing, which also rely on industrial control systems, Gresham said.

Tim Francis, enterprise cyber lead, Travelers, noted that insurers and the private sector have dealt with the threat of data breaches for a while, but are “just beginning the journey” on threats to industrial control systems.

For businesses, it may come down to a question of size and scale, said Bouloux.

“Ultimately, if you are a big enough business, you should be able to marginalize the exposure due to a power outage,” he said.

Experts often compare the impact of a power grid hack to the damage and losses resulting from large natural disasters such as Katrina and Sandy, but Bouloux said 9/11 might be a better model for understanding the economic impact such an event could have on the insurance industry, if it was found to be an act of terrorism.

Commercial claims in the New York area alone were varied and complicated — amounting to about $40 billion, of which an estimated $27 billion was paid in claims associated with business interruption, liability and property damage (other than damage to the World Trade Center buildings), he said.

As a single, isolated act of terrorism, it calls into question Lloyd’s estimated insured losses from the 15-state blackout scenario of $21.4 billion to $71.1 billion.

The cascading impact of a cyber attack complicates the picture for insurers.

“They need to look at how many insureds’ policies they have that have certain coverages on them,” said Andrew Coburn, senior vice president, RMS, and director of the advisory board at the Cambridge Centre for Risk Studies.

“About 12 classes of insurance lines were impacted in the scenario,” he said.

The formula to determine potential losses is complex, often depending on whether companies have “supplier’s extension coverage,” which may have ambiguous wording relating to perils.

To come up with a potential loss, the insurance companies need to work through how long each insured is impacted — which could range from one to four weeks or more — and then take into account deductibles, limits and sublimits, Coburn said.

“We spent the past couple of months working with insurance companies to apply this to their book as a stress test scenario,” he said. “It’s not the easiest one for them.”

Risk Mitigation

Regardless of whether a power outage is due to a natural event or a cyber attack, companies need to prepare in similar ways, Francis said.

They need back-up continuity plans, plans for employees working offsite, and they

need to talk to their broker and insurer prior to any such event to determine what is covered and what gaps exist.

Experts said coverage is available to cover most exposures related to a power-grid attack, but one policy alone will probably be insufficient. For example, power

outages are generally not covered by insurance policies — such as for property coverage — unless there is physical damage.

When planning for continuity, risk managers should look at the electric grid and ensure they have facilities in other grids so those facilities would not be affected, Bouloux said.

Effective mitigation requires an ongoing review of potential exposures from an enterprise risk management perspective, said Gresham.

Risk managers must continually review and update processes and practices to ensure the organization is as resilient as possible and operations have redundancy.

Aon’s Kalinich said it’s possible for insureds to identify and quantify their business interruption losses on a micro level. “The bigger question,” he said, “is the macro level aggregated risk of grid-type exposures” for insurance companies.

“For us, it’s not an academic exercise,” Beecroft of Lloyd’s said. “It’s a real challenge for the industry. We have to be able to pay out claims.

“We recognize that there is a large degree of ambiguity and uncertainty about whether or not existing insurance covers would respond in the event of a cyber event.”

Managing the risk requires a partnership of government, insurance and business, he said. “We can’t just accept the vulnerability and throw our hands up. We can manage to make life difficult for hackers, but we can’t reduce the risk to zero.”

“Cyber,” said Coburn, “is definitely the most dangerous emerging risk. The digital infrastructure was not designed to protect against bad guys. It was designed to be efficient. … What is society willing to spend to make that threat go away?” &

2018 Most Dangerous Emerging Risks

Emerging Multipliers

It’s not that these risks are new; it’s that they’re coming at you at a volume and rate you never imagined before.
By: | April 9, 2018 • 3 min read

Underwriters have plenty to worry about, but there is one word that perhaps rattles them more than any other word. That word is aggregation.

Advertisement




Aggregation, in the transferred or covered risk usage, represents the multiplying potential of a risk. For examples, we can look back to the asbestos claims that did so much damage to Lloyds’ of London names and syndicates in the mid-1990s.

More recently, underwriters expressed fears about the aggregation of risk from lawsuits by football players at various levels of the sport. Players, from Pee Wee on up to the NFL, claim to have suffered irreversible brain damage from hits to the head.

That risk scenario has yet to fully play out — it will be decades in doing so — but it is already producing claims in the billions.

This year’s edition of our national-award winning coverage of the Most Dangerous Emerging Risks focuses on risks that have always existed. The emergent — and more dangerous — piece to the puzzle is that these risks are now super-charged with risk multipliers.

Take reputational risk, for example. Businesses and individuals that were sharply managed have always protected their reputations fiercely. In days past, a lapse in ethics or morals could be extremely damaging to one’s reputation, but it might take days, weeks, even years of work by newspaper reporters, idle gossips or political enemies to dig it out and make it public.

Brand new technologies, brand new commercial covers. It all works well; until it doesn’t.

These days, the speed at which Internet connectedness and social media can spread information makes reputational risk an existential threat. Information that can stop a glittering career dead in its tracks can be shared by millions with a casual, thoughtless tap or swipe on their smartphones.

Aggregation of uninsured risk is another area of focus of our Most Dangerous Emerging Risks (MDER) coverage.

The beauty of the insurance model is that the business expands to cover personal and commercial risks as the world expands. The more cars on the planet, the more car insurance to sell.

The more people, the more life insurance. Brand new technologies, brand new commercial covers. It all works well; until it doesn’t.

As Risk & Insurance® associate editor Michelle Kerr and her sources point out, growing populations and rising property values, combined with an increase in high-severity catastrophes, threaten to push the insurance coverage gap to critical levels.

This aggregation of uninsured value got a recent proof in CAT-filled 2017. The global tally for natural disaster losses in 2017 was $330 billion; 60 percent of it was uninsured.

This uninsured gap threatens to place unsustainable pressure on public resources and hamstring society’s ability to respond to natural disasters, which show no sign of slowing down or tempering.

A related threat, the combination of a failing infrastructure and increasing storm severity, marks our third MDER. This MDER looks at the largely uninsurable risk of business interruption that results not from damage to your property or your suppliers’ property, but to publicly maintained infrastructure that provides ingress and egress to your property. It’s a danger coming into shape more and more frequently.

As always, our goal in writing about these threats is not to engage in fear mongering. It’s to initiate and expand a dialogue that can hopefully result in better planning and mitigation, saving the lives and limbs of businesses here and around the world.
