LONDON (September 28, 2012)--U.S. banks have been hit by more than week of powerful cyberattacks whose perpetrators remain unknown.
A series of American financial institutions experienced disruptions after sites were overwhelmed by unusually high amounts of traffic.
An expert whose company has analyzed some of the rogue traffic says that while the cyberassaults weren’t sophisticated, they ranked among the largest he had ever seen.
Mike Smith, with Web security company Akamai, said Friday the attacks delivered about three times the amount of traffic typically used by criminals to jam e-commerce websites.
Responsibility for online attacks is difficult to prove, but speculation has focused on an Internet posting suggesting that Islamists were taking revenge for an anti-Muslim film, which has sparked violent protests across the Middle East.
