Un marché de hackers ?

NEW YORK – Jamais dans l'histoire de la communication écrite, 140 caractères n’ont pu avoir l'impact qu'ils peuvent avoir aujourd’hui. Il y a deux semaines, après avoir piraté le principal compte Twitter del’Associated Press (@AP), l'Armée Electronique Syrienne (SEA) a publié un faux tweet faisant état de deux explosions à la Maison Blanche qui auraient blessé le président Barack Obama. En quelques secondes, les marchés financiers américains chutèrent d'environ 1%.

Quelques minutes plus tard, des réfutations en tous sens ont inondé Twitter. Les journalistes présents à la Maison Blanche tweetèrent qu'ils n’avaient ressenti aucune explosion et les journalistes d'AP ainsi que le compte Twitter AP Politics annoncèrent que @AP avait été piraté. Lors de son briefing d'après-midi, l’attaché de presse de la Maison Blanche Jay Carney confirma que M. Obama était effectivement sain et sauf. Les marchés financiers revinrent enfin à leur niveau d'avant-canular.

Le piratage du compte Twitter @AP représente un risque systémique qui ne peut pas être éliminé, car il découle de l'interaction de marchés financiers hautement intégrés et d’une fourniture d’information de plus en plus démocratisée. Compte tenu des fortes incitations pour des parties malicieuses à perpétrer de tels canulars, nous devrions nous attendre à voir une augmentation du nombre de ce genre d'incidents.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.

    The Holy Grail of Genetic Engineering

    CRISPR-Cas – a gene-editing technique that is far more precise and efficient than any that has come before it – is poised to change the world. But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
