We're living in the age of the hacker

Hack or be hacked.

Never in the history of written communication could 140 characters have the impact that they can have now

Two weeks ago, after gaining access to the Associated Press’s main Twitter account (@AP), the Syrian Electronic Army (SEA) posted a fake tweet reporting two explosions in the White House and the injury of President Barack Obama. Within seconds, US financial markets dropped by about 1%.

Minutes later, Twitter was abuzz with refutations. Reporters at the White House tweeted that they felt no explosion, and AP reporters and the AP Politics Twitter account announced that @AP had been hacked. At his afternoon briefing, White House press secretary Jay Carney confirmed that Obama was indeed unharmed. Financial markets returned to their pre-hoax level.

The @AP Twitter hoax represents systemic risk that cannot be eliminated, for it arises from the interaction of highly integrated financial markets and increasingly democratized news delivery. Given strong incentives for malicious parties to perpetrate such hoaxes, we should expect to see an increase in incidents.

Financial markets are vulnerable to manipulation, because they are not in the business of evaluating the truth. Trading often favours first movers, so being fast but wrong can still be profitable.

Imagine that a sophisticated trading firm has invested significant resources to develop an algorithm that quickly evaluates the potential market impact of news, and then automatically sends orders to trade based on that predicted impact. When that algorithm parses a tweet from the AP containing important keywords (explosion, White House, and Obama), it will send orders to sell with the expectation that the market will drop as others – first, slower algorithms, then even slower humans – start to process the same news.

The first mover is happy to make such trades without verifying that the news is true. If it is true, the market will stay down or continue dropping, and the first mover will profit from the sales that it has made. If the story is a hoax, the market will probably return to its earlier, fairly valued level, and the first mover will break even on its sales, and possibly profit from any position purchased as a hedge when the market was down. The first mover’s algorithm worked, regardless of the story’s veracity.

The likely losers in the @AP Twitter hoax were later movers who did not react quickly to the news, but reacted instead to the market’s movement.

These late movers were also likely to have been sophisticated electronic or institutional traders; some were probably using arbitrage-based strategies that relied on the futures market for a calculation of the fair price.

The market’s vulnerability to hoax stories is thus difficult to eliminate, for it is inherent in its structure. It cannot be regulated away or fixed by technology or surveillance.

Even if markets moved more slowly, there would still be a first mover who responded before such a news story was revealed as a hoax. This dynamic is similar to that of an asset bubble, albeit faster. In a bubble, valuations are based on collectively evaluated evidence, and those who enter the market earliest often benefit. Whether evaluating an assumption about the rise of house prices or whether a news story is true, the market does not provide a definitive answer instantaneously.

If protecting against hoaxes is not the market’s purview, can news agencies or new media entities like Twitter prevent such deception? To be sure, they have suffered reputational damage from this fiasco and will likely try to improve. But their efforts will not be enough.

Twitter’s vulnerabilities were technically understood before this event, and the service was already moving toward a more sophisticated authentication model (a password paired with a one-time key from a text message or other device). Twitter will likely implement this soon. It should also consider adding an optional “two-key” system, in which an independent signoff from a separate account is required before a proposed tweet is broadcast. But, while such measures would increase the difficulty of hacking the system, no technological fix can make it impenetrable.

What about the AP’s vulnerabilities? Attackers launched a “phishing” attempt against the AP’s emails shortly before the hoax tweet was sent. Phishing attacks, in which an employee is duped into sending a password to a third party or clicking an untrusted link that installs malicious software, represent a hybrid of cultural and technological failures.

As attackers become more sophisticated, they send better-crafted emails, sometimes impersonating trusted sources that lure unwary users. Crafting a culture of security is difficult and often at odds with the dynamic and decentralised work environment of a fast-moving newsroom.

"Michael Gove is a nasty bit of work": A Thatcherite's lonely crusade for technical colleges

Kenneth Baker, Margaret Thatcher's education secretary, has been in a war of words with one of his successors. 

When I meet Kenneth Baker, once Margaret Thatcher’s reforming education secretary, conversation quickly turns to an unexpected coincidence. We are old boys of the same school: a sixth-form college in Southport that was, in Baker’s day, the local grammar. Fittingly for a man enraged by the exclusion of technical subjects from the modern curriculum, he can only recall one lesson: carpentry.

Seven decades on, Lord Baker – who counts Sats, the national curriculum, league tables, and student loans among his innovations – is still preoccupied with technical education. His charity, the Baker Dearing Educational Trust, oversees university technical colleges (UTCs), the specialist free schools that work with businesses and higher education institutions to provide a vocational curriculum for students aged 14-19. He is also a working peer, and a doughty evangelist for technical education and apprenticeships in the upper chamber. 

But when we meet at the charity’s glass-panelled Westminster office at 4 Millbank, he is on the defensive – and with good reason. Recent weeks have been particularly unkind to the project that, aged 82, he still works full-time to promote. First, a technical college in Oldham, Greater Manchester, became the seventh to close its doors since 2015. In three years, not one of its pupils passed a single GCSE, and locals complained it had become a “dumping ground” for the most troubled and disruptive children from Oldham’s other schools (Baker agrees, and puts the closure down to “bad governorship and bad headship”). 

Then, with customary chutzpah, came Michael Gove. In the week of the closure, the former education secretary declared in his Times column that the UTCs project had failed. "The commonest error in politics," he wrote, quoting Lord Salisbury, "is sticking to the carcasses of dead policies". Baker is now embroiled in a remarkable – and increasingly bitter – war of words with his successor and one-time colleague.

It wasn't always this way. In 2013, with UTCs still in their infancy, he told the New Statesman the then education secretary was “a friend”, despite their disagreements on the curriculum. The bonhomie has not lasted. In the course of our hour-long conversation, Gove is derided as “a nasty bit of work”, “very vindictive”, “completely out of touch”, and “Brutus Gove and all the rest of it”. (Three days after we speak, Baker renews their animus with a blistering op-ed for The Telegraph, claiming Gove embraced UTCs about as warmly as “an undertaker”.)

In all of this, Gove, who speaks warmly of Baker, has presented himself as having been initially supportive of the project. He was, after all, the education secretary who gave them the green light. Not so, his one-time colleague says. While David Cameron (Baker's former PA) and George Osborne showed pragmatic enthusiasm, Gove “was pretty reluctant from the word go”.

“Gove has his own theory of education,” Baker tells me. He believes Gove is in thrall to the American educationalist E.D. Hirsch, who believes in focusing on offering children a core academic diet of subjects, whatever their background. "He doesn’t think that schools should worry about employability at all," Baker says. "He thinks as long as you get the basic education right, everything will be fine. That isn’t going to happen – it isn’t how life works!" 

Baker is fond of comparing Gove’s heavily academic English baccalaureate to the similarly narrow School Certificate he sat in 1951, as well as the curriculum of 1904 (there is seldom an interview with Baker that doesn’t feature this comparison). He believes his junior's divisive tenure changed the state sector for the worse: “It’s appalling what’s happening in our schools! The squeezing out of not only design and technology, but drama, music, art – they’re all going down at GCSE, year by year. Now children are just studying a basic eight subjects. I think that’s completely wrong.” 

UTCs, with their university sponsors, workplace ethos (teaching hours coincide with the standard 9-5 working day and pupils wear business dress), and specialist curricula, are Baker's solution. The 46 existing institutions teach 11,500 children, and there are several notable success stories. GCHQ has opened a cyber-security suite at the UTC in Scarborough, North Yorkshire, as part of a bid to diversify its workforce. Just 0.5 per cent of UTC graduates are unemployed, compared to 11.5 per cent of all 18-year-olds. 

But they are not without their critics. Teaching unions have complained that their presence fragments education provision and funding, and others point out that hard-up schools in disadvantaged areas have little desire or incentive to give up children – and the funding they bring – at 14. Ofsted rate twice as many UTCs as inadequate as they do outstanding. Gove doubts that the vocational qualifications on offer are as robust as their academic equivalents, or anywhere near as attractive for middle-class parents. He also considers 14 is too young an age for pupils to pursue a specialist course of vocational study.

Baker accepts that many of his colleges are seen as “useless, wastes of money, monuments to Baker’s vanity and all the rest of it”, but maintains the project is only just finding its legs. He is more hopeful about the current education secretary, Justine Greening, who he believes is an admirer. Indeed, UTCs could provide Greening with a trump card in the vexed debate over grammar schools – last year’s green paper suggested pupils would be able to join new selective institutions at 14, and Baker has long believed specialist academic institutions should complement UTCs.

Discussion of Theresa May’s education policy has tended to start and finish at grammar schools. But Baker believes the conversation could soon be dominated by a much more pressing issue: the financial collapse of multi-academy trusts and the prospect of an NHS-style funding crisis blighting the nation’s schools. Although his city technology colleges may have paved the way for the removal of more and more schools from the control of local authorities, he, perhaps surprisingly, defends a connection to the state.

“What is missing now in the whole education system is that broker in the middle, to balance the demands of education with the funds available," he says. "I think by 2020 all these multi-academy trusts will be like the hospitals... If MATs get into trouble, their immediate cry will be: ‘We need more money!’ We need more teachers, we need more resources, and all the rest of it!’."

It is clear that he is more alert to coming challenges, such as automation, than many politicians half his age. Halfway through our conversation, he leaves the room and returns enthusiastically toting a picture of an driverless lorry. It transpires that this Thatcherite is even increasingly receptive to the idea of the ultimate state handout: a universal basic income. “There’s one part of me that says: ‘How awful to give someone a sum for doing nothing! What are they going to do, for heaven’s sake, for Christ’s sake!’" he says. "But on the other hand, I think the drawback to the four-day working week or four-hour working day... I think it’s going to happen in your lifetime. If people are only working for a very short space of time, they will have to have some sort of basic income.” 

Predictably, the upshot of this vignette is that his beloved UTCs and their multi-skilled graduates are part of the solution. Friend and foe alike praise Baker’s indefatigable dedication to the cause. But, with the ranks of doubters growing and the axe likely to fall on at least one of its institutions again, it remains to be seen in what form the programme will survive.

Despite the ignominy of the last few weeks, however, Baker is typically forthright: “I sense a turning of the tide in our way now. But I still fight. I fight for every bloody one.”
