The digital attack that brought Estonia to a standstill 10 years ago was the first shooting in a cyberwar that has been raging between Moscow and the west ever since

It began at precisely 10 pm on 26 April, 2007, when a Russian-speaking mob began rioting in the streets of Tallinn, the capital city of Estonia, killing person or persons and wounding dozens of others. That incident resonates powerfully in some of the recent conflicts in the US. In 2007, the Estonian government had announced that a bronze statue of a heroic second world war Soviet soldier was to be removed from a central city square. For ethnic Estonians, the statue had less to do with the war than with the Soviet occupation that followed it, which lasted until independence in 1991. For the country's Russian-speaking minority- 25% of Estonia's 1.3 million people- the removal of the memorial was another sign of ethnic discrimination. Russia's government warned that the statue's removal would be “disastrous” for Estonia.

That evening, Jaan Priisalu- a former danger director for Estonia's largest bank, Hansabank, who was working closely with the governmental forces on its cybersecurity infrastructure- was at home in Tallinn with his girlfriend when his phone resound. On the line was Hillar Aarelaid, the chief of Estonia's cybercrime police.

“It's going down,” Aarelaid declared. Alongside the street fighting, the reporting of digital attacks were beginning to filter in. The websites of the parliament, major universities, and national newspapers were crashing. Priisalu and Aarelaid had suspected something like this could happen one day. A digital attack on Estonia had begun.

Estonia boastings the most technologically advanced system of government in the world. Every citizen possesses a digital identity- an identification number and login code for access to completely digitised interactions with the state. Estonians can vote online, filetheir taxes, check medical records, access “the member states national” health care system, and receive notifications of most government attempts to access their personal records. About 97% of the country employs digital banking. The Estonian national ethic is dependent upon the idea that every citizen is transparent and the state is too. This stimulates Estonia highly efficient- and extremely vulnerable.” We live in the future. Online banking, online news, text messages, online shopping- total digitisation has stimulated everything quicker and easier ,” Priisalu said.” But the committee is also generates the possibility that we can be thrown back centuries in a couple of seconds .”

Over the following two nights, as the street battles began to wane, the two attacks on Estonia's technological infrastructure picked up. The authorities were slow to recognise what was happening. It wasn't until 24 hours later when the national defence pastor realised he was unable to log on to the ruling party's website that they knew they had a major problem on their hands. Then the mail server that the european parliament is crashed. News sites began to falter. Some of the country's most widely read publications vanished altogether.

Priisalu began to analyse the streams of data besieging the country's organizations. Vast ” botnets”- networks of captured and linked computers- were attempting to bring down computer systems with automated queries as part of a large DDoS( distributed denial-of-service) assault. “Mail-bombing” email barrages and volleys of status and location queries overloaded servers across the country, bringing crucial parts of the Estonian internet to a halting. Some websites, in agreement with the BBC, were “defaced,” redirecting users” to images of Soviet soldiers and excerpts from Martin Luther King Jr about resisting evil “.” War dialling “, in which automated telephone call target a company or institution, placed a virtual blockade on phone number for government offices and parliament. On 10 May, Hansabank, Estonia's biggest bank, had to cease online services and international card transactions temporarily.

The digital firepower arrayed against Estonia was massive and intense. One thousand data packets per hour were travelling through the country's networks on the first day. On the second day, it was 2,000 per hour. At its highest point, it was 4m per second. Ordinary computer users, many of them with no prior hacking experience, volunteered to become” script kiddies ,” exerting premade freeware code scripts to contribute to the attack. Botnets cost money, and this was funded by online accounts that anyone could pay into. The assaults seemed somehow “mustve been” outsourced, with the costs of the aggression crowdfunded.

The government was amazed. Were the attacks the opening moves of a military intrusion? Estonia had recently joined Nato, despite the vocal protests of its Russian neighbour. Should it activate Article 5, the mutual defence clause of the security group's charter?

Finally, on 19 May, 2007, the attacks were stopped. The Estonians had implemented a simple, almost absurdly sad answer: they pulled the plug. The most wired country in the world severed its international electronic connections and largely disappeared from the internet, bringing what military historians now call the first internet war to an abrupt halt. It was a decisive victory for whoever had perpetrated the attacks.

No one has in the past claimed responsibility, but it soon became apparent to Priisalu and many others that Russia was responsible. Russia had an obvious, and publicly stated, political motive: its opposition to the removal of the statue. More importantly, the events in Estonia helped crystallise an emerging consensus that cyber-attacks could constitute warfare. The attacks on its digital infrastructure had paralysed parliament, shut down banks, and fuelled violence in the street. It was, Priisalu concluded, undoubtedly an act of war.

Perhaps more telling was the fact that the strategies being implemented in Estonia had already been included in a Russian manual of war. In 1998, Sergei P Rastorguev, a Russian military analyst, published Philosophy of Information Warfare , which included a lengthy version of this anecdote 😛 TAGEND

Once there was a fox that wanted to eat a turtle, but whenever he tried to, it receded into its shell. He bit it and he shook it, but he wasn't getting anywhere. One day he had an idea: he made the turtle an offer to buy its shell. But the turtle was clever and knew it would be eaten without this protection, so it rejected. Time passed, until one day there appeared a television hanging in a tree, displaying images of flocks of happy, naked turtles- flying! The turtle was surprised. Oh! They can fly! But wouldn't it be dangerous to give up your shell? Hark, the voice on television was announcing that the fox had become a vegetarian.” If I could only take off my shell, my life would be so much easier ,” thought the turtle.” If the turtle would only give up its shell, it would be so much easier to feed ,” believed the fox- and paid for more broadcasts advertising flying turtles. One morning, when the sky seemed bigger and brighter than usual, the turtle removed its shell. What it fatally failed to understand was that the aim of information warfare is to induce an adversary to let down its guard.

Rastorguev said that one of the best available weapons in modern conflict was information- or more accurately, disinformation, like the fake news and social media posts that US audiences have been reading since last year's general elections, or the stories that whipped Estonian protesters into a craze in 2007. The core concept of cyberwar has to be understood as something broader than hacks or the defacement of websites. It is psychological manipulation, executed with targeted digital disinformation designed to weaken a country from within. Thus , no smoking gun will ever be found:” The Russian theory of war allows you to defeat the foe without ever having to touch him ,” says Peter Pomerantsev, writer of Nothing is True and Everything is Possible .” Estonia was an early experiment in that hypothesi .”

Since then, Russia has only developed, and codified, these strategies. The techniques pioneered in Estonia are known as the” Gerasimov doctrine ,” named after Valery Gerasimov, the chief of the general staff of the Russian military. In 2013, Gerasimov published an article in the Russian publication Military-Industrial Courier , enunciating the strategy of what is now called ” hybrid” or “nonlinear” warfare.” The lines between war and peace are blurred ,” he wrote. New different forms of antagonism, as seen in 2010′ s Arab spring and the” colouring revolutions” of the early 2000 s, could transform a” perfectly thriving state, in a matter of months, and even days, into an arena of fierce armed conflict “.

Russia has deployed these strategies around the globe. Its 2008 war with Georgia, another former Soviet republic, are dependent upon a mix of both conventional and cyber-attacks, as did the 2014 invasion of Crimea. Both began with civil unrest triggered via digital and social media- followed by tanks. Finland and Sweden have experienced near-constant Russian datum operations. Russian hacks and social media operations have also passed during recent elections in Holland, Germany, and France. Most lately, Spain's resulting daily, El Pais , reported on Russian meddling in the Catalonian freedom referendum. Russian-supported hackers is reportedly worked with separatist groups, presumably with a mind to farther undermining the EU in the wake of the Brexit vote.

As the smoking gun is often missing, we shouldn't fall for every allegation of assumed Russian involvement. Still, certain patterns have emerged from these conflicts, allowing experts to draft a rough model of the techniques Russia uses to destabilise its foes. First, people's trust in one another is broken down. Then comes dread, followed by hatred, and finally, at some phase, shots are fired. The pattern was especially striking in Crimea. People posted reports on Facebook about gross mistreatment by Ukrainians; dramatic messages circulated on Instagram about rivers of refugees fleeing the country; billboards suddenly appeared in Kiev bearing pro-Russian slogans; demonstrations followed. Rising mistrust and mutual mistrust divide Ukrainian society. In a matter of months, fighting broke out. Russia use the conflict as a pretext to send in” aid escort”, presenting itself as a benevolent responder to an emergency.

The Kremlin has use the same strategies against its own people. Domestically, history books, school lessons, and media are manipulated, while laws are passed blocking foreign access to the Russian population's online data regarding foreign companies- an essential resource in today's global information-sharing culture. According to British military researcher Keir Giles, author of Nato's Handbook of Russian Information Warfare , the Russian government, or actors that it supportings, has even captured the social media accounts of celebrities in order to spread provocative messages under their names but without their knowledge. The objective, both at home and abroad, is to sever outside lines of communication so that people get their information purposes through controlled channels.

We spoke with Priisalu on got a couple of occasions earlier this year and asked him what we should be most afraid of. Priisalu considered this for a moment.” Information war ,” he said.

Since 2007, Estonia has established itself as a global hub for thinking about cyber-attacks and, more broadly, about what constitutes an act of war in the internet age. Priisalu has been at the forefront. In 2008, he helped establish the Cooperative Cyber Defence Centre of Excellence, a Nato-funded international research centre in Tallinn that brings together cybersecurity experts from around the world. Each year the centre hosts Locked Shields, the world's largest international cyberwar exercise. In this year's simulation, 25 member states enlisted representatives to fight off thousands of simultaneous attacks on a virtual country called Crimsonia. The progression of the battle was rendered visually and beamed on to giant screens. Some “soldiers” came in suits, others in sweatshirts- but most logged in from home.

Priisalu has also helped build Europe's first volunteer cyber-army. In 2011, his network of freelance cyberfighters was consolidated into a new sub-unit of the Estonian military's armed reserves, the paramilitary Estonian Defence League. The logo of the Estonian Cyber Defence Unit( CDU) depicts an eagle with a sword in its right claw and a shield in its left displaying [email protected] sign. The names of its members and the numbers in its ranks are secret. If called on in an emergency, they will take up combat stations at their computers.

The US has adopted some of Estonia's programs in its own efforts to combat cyber incursions. In 2009, the American administration established its own Cyber Command centre, under the NSA, at Fort Meade in Maryland. Last July, the Trump administration split the command off as an independent agency with a proposed draft $647 m annual budget, 133 operational teams and as many as 6,200 workers. Likewise, the Department of Defense has developed its own cybersecurity infrastructure, with dedicated digital” national mission teams” and” combat mission teams “. But the next step in the west's collective defensive strategy is to develop a consensus about what, legally, constitutes an act of cyberwar.

The question is how the west can maintain its core values of freedom of speech and the free flow of information while protecting itself from malevolent geopolitical actors? For centuries, eastern European countries such as Estonia relied on walls, watchtowers, and fortresses to keep out invaders. The US became the world's most powerful country in part because it was insulated from foreign menaces by vast oceans on two sides. In the internet age, traditional perimeters are less effective.

To survive in the era of information war, any society will have to create ways of withstanding cyber-attacks. Blockchain technology, the underlying protocol of cryptocurrencies such as bitcoin, might for example function as a sort of digital fortress protecting the secure exchange of information online. Whatever form these defenses take, democratic countries will have to focus more resources on procuring and spreading potent and dependable technologies, whether in partnership with private companies or in government cyber labs in Estonia or the US. But we will also have to accept the sobering reality that these attacks, like guerilla warfare and suicide bombings, aren't going away. What's more, other countries area already aping thesis techniques. Russia may be the world's most open cyberwarfare aggressor -but it' s far from the only one. Iran, Israel, North Korea and the United States, and perhaps other countries, are all active. Permanent globalized digital war might become the new cost of living in a connected world.
