The financial industry has done such a good job of bringing itself to its knees over the past four years that it is easy to overlook the threats it faces from outside. High among them is electronic attack. In 2010 Symantec, a cybersecurity firm, estimated that three-quarters of all “phishing” attacks, in which people are deceived into surrendering private details such as account numbers, are aimed at the finance sector. Bob Greifeld, the boss of NASDAQ, has described his bourse as being under “literally constant attack”.Many of these assaults are carried out by hackers bent on mischief. Some are the work of organised criminal groups in pursuit of loot. But plenty of people fret that some attackers are aiming to cause more serious damage.
