Here’s how to shut down the internet: Snip undersea fiber-optic cables

WASHINGTON
Hundreds of thousands of miles of fiber-optic cable lay on the ocean floors, a crucial part of the global internet’s backbone, and only rarely do ship anchors, undersea landslides or saboteurs disrupt them.
Still, a few voices now call for stronger global mechanisms and even military action to protect the cables against future malicious activity by states, saboteurs or extremists.
“The infrastructure that underpins the internet – these undersea cables – are clearly vulnerable,” said Rishi Sunak, a British member of Parliament and champion of more vigorous action to protect submarine networks. “They underpin pretty much everything that we do.”

Undersea cables conduct nearly 97 percent of all global communications, and every day an estimated $10 trillion in financial transfers and vast amounts of data pass through the seabed routes. Satellites, once crucial but now limited in speed and bandwidth, handle only a tiny percentage of global communications.
As reliance on the underwater cables soars, a growing list of countries – and even companies – have the expertise to deploy unmanned vehicles to ocean depths to access them.
“Nowadays, there are a lot of countries and companies that have the ability to send vehicles down to the sea floor and have them manipulate, install or take away undersea cables,” said Bryan Clark, a retired naval submariner and former Navy strategist who is a senior fellow at the Center for Strategic and Budgetary Assessments, a Washington think tank.
The optical strands inside the cables have extraordinary capacity to transmit data, millions of phone calls per fiber. The cables that house bundled fiber optics are no thicker than a human wrist.
Failures along cable routes are rare, numbering on average barely 200 a year along the estimated 650,000 miles of active international commercial cables laid along sea beds.

“It’s still vanishingly small when the amount of cable around the globe is considered,” said Keith Schofield, general manager of the International Cable Protection Committee, which has its headquarters in Lymington, England.
There are 428 known commercial fiber-optic cable routes worldwide. Many cables are laid parallel along heavily trafficked routes, like the U.S. to Britain, or through the Mediterranean and Red Sea toward India and the rest of Asia, and come ashore together. Florida has about 10 landing points for the two dozen or so cables that come ashore there.
Most problems occur close to landfall, not in the open ocean, and the majority involve nets from trawlers or damage by anchors, Schofield said.
But in recent years, a few incidents have drawn attention to sabotage and espionage.
In October 2015, U.S. authorities scrambled to monitor Russian submarine patrols and a high-tech Russian surface ship, the Yantar, in a corridor of the North Atlantic that hosts a cluster of undersea cables. The Yantar carried deep-sea submersibles and cable-cutting gear.

I saw that and almost posted earlier.

Banks and other financial institutions push enormous volumes of info on those fiber highways - drop a certain cable or so out of commmision and crush an economy.

IIRC, embedded in that story are links to some cool maps of where those cables are located . A million years ago I spent more than a few months of my life working on a transoceanic fiber-optic cable issue - article brought back memories.

That fiber optic stuff really pretty cool.

A CARVER matrix on that target, derived wholly from open-source info, would be pretty interesting.

According to the book "Blind Man's Bluff" those undersea cables at one time were vulnerable to tapping devices placed by US Submarines.

More on undersea cables - lots of links embedded in story.

Could Russia cut undersea communication cables?
BBC
15 December 2017

The UK's top military officer has warned that Russia could strike a "catastrophic" blow to the economy by targeting communications and internet cables that run under the sea.

Air Chief Marshal Sir Stuart Peach, the chief of the defence staff, said the lines could potentially be cut or disrupted.

The suggestion raises several questions:
Is that something Russia's likely to do?
What would happen if they - or someone else - did such a thing?

What do the cables do?

They provide internet and communications links between separate countries and continents.

The full network of around 428 cables spans 683,508 miles (1.1 million km), circling the globe.

Huge quantities of data fly around under the waves, in cables filled with fibre optics - strands of glass as thin as a sheet of paper.

Unfortunately, while their technology is reliable, these pivotal cables are physically fragile. The fibres are encased in steel wire and then coasted in plastic - but many cables are still only around 3cm in diameter.

Natural disasters can damage them and even a ship dropping anchor can sever a cord. That's happened before at the port of Alexandria in Egypt, straining connections between Europe, Africa and Asia.

Why are defence chiefs worried?
The BBC's defence correspondent, Jonathan Beale, says fears of Russia cutting, disrupting or "wire-tapping" undersea communication lines are growing.
Defence and intelligence chiefs cite the country's modernised navy, increased submarine activity and willingness to use information warfare.

Are Russia's military advances a problem for Nato?
Russian subs are increasingly present in the North Atlantic, particularly the GIUK Gap, a strip of ocean between Greenland, Iceland, and the UK.

Air Chief Marshal Peach is flagging up that Britain and its Nato allies lack the subs, ships and aircraft to sustain constant vigilance.

Our correspondent notes that the UK will get new Maritime Patrol Aircraft within the next decade, but until then is reliant on Nato support to spot subs.

Nato's former top military chief, Admiral James G Stavridis, is also concerned. "We've allowed this vital infrastructure to grow increasingly vulnerable and this should worry us all," he said recently.

What would happen if the cables were cut?

Keir Giles, an expert in Russian information warfare who works with the Chatham House think tank, stresses that this is not a new concern.

He thinks it's unlikely to happen as the economic fallout would also affect Russia "but it is definitely a scenario for which they are practising".
And if it did happen, the damage would be considerable.

"The fact that people wouldn't be able to log on to Facebook would be just a tiny, tiny aspect of all the disruption that would be caused if these cables were interfered with," says Mr Giles.

"International trading and financial transactions are managed across sub-sea cables. The economic impact would be enormous and immediate."

He believes Russia is conflict-proofing itself, "seeking to reduce its reliance on the correct functioning of the internet by setting up its own parallel systems", and rehearsing for what would happen if its internet connection collapsed.

Russia is not the only nation with an interest in undersea cables. During the Cold War, for example, the US attached a recording device to a Soviet cable to learn more about the USSR's submarine and missile capabilities.

However, Mr Giles says it's the only state "with an intensive programme looking at ways of isolating targets from information".

Has Russia attempted to disrupt UK cables in the past? We can't be sure - it's classified.

What's in it for Russia?
Information control, in short.

"They are probing the vulnerabilities of civilian communications infrastructure," Mr Giles says.

"You can't see what they're doing underwater. You can see what they're doing on land or with satellites.

"What Russia learned from Crimea is that in order to take over communications for a target area you don't need expensive cyber weapons, you don't need noisy and disruptive techniques like denial of service attacks.

"All you need is physical access to the communications infrastructure and telecommunications expertise embedded with your special forces.

"They've been looking everywhere. They've been looking on land in the United States, they've been looking on land in eastern Europe... Anywhere that might in future be in an adversarial relationship with Russia should be concerned about this fixation that they have on achieving information dominance."

Yep. "Do onto others...."

The Ruskies giving us a taste of our own medicine from days gone by.

For disruption alone, perhaps even a poor's man method can work with good ol weight, underwater cam/fishing sonar, and HE

I wonder if the Jimmy Carter has an alibi? :D
