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.

    The Next Battle in China’s War on Corruption

    • Chinese President Xi Jinping knows well the threat that corruption poses to the authority of the Communist Party of China and the state it controls. 
    • But moving beyond Xi's anti-corruption purge to build robust and lasting anti-graft institutions will not be easy, owing to enduring opportunities for bureaucratic capture.

    Putting Europe’s Long-Term Unemployed Back to Work

    Across the European Union, millions of people who are willing and able to work have been unemployed for a year or longer, at great cost to social cohesion and political stability. If the EU is serious about stopping the rise of populism, it will need to do more to ensure that labor markets are working for everyone.

    A Belt and Road for the Americas?

    In a time of global uncertainty, a vision of “made in the Americas” prosperity provides a unifying agenda for the continent. If implemented, the US could reassert its historical leadership among a group of countries that share its fundamental values, as well as an interest in inclusive economic growth and rising living standards.

    How Best to Promote Research and Development

    Clearly, there is something appealing about a start-up-based innovation strategy: it feels democratic, accessible, and so California. But it is definitely not the only way to boost research and development, or even the main way, and it is certainly not the way most major innovations in the US came about during the twentieth century.

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.
