Cyberattacks now have the potential to ‘down’ one or more of the world’s major financial securities exchanges, a survey of the sector by industry body International Organization of Securities Commissions (IOSCO) has found.

Just over half the 46 securities exchanges surveyed by IOSCO from across the globe reported that they’d been targeted by cyberattacks in 2012, overwhelmingly “disruptive” DDoS designed to interrupt business.
