Bank Cyber Attacks Enter Fifth Week as Hackers Adapt to Defenses

Capital One Financial Corp., BB&T Corp. and HSBC Bank USA said they were hit by a new round of cyber attacks, marking the fifth week of sustained assault on some of the largest U.S. financial institutions.

The banks’ websites have been disrupted with so-called denial of service attacks, some of which originated in Iran and Russia, Carl Herberger, a vice president for the network security firm Radware Inc., said in a phone interview yesterday.
