Hackers more aggressive in attacking bank accounts

A survey of large financial institutions shows they faced more attacks by hackers to take over customer banking accounts last year than in the two previous years, and about a third of these attacks succeeded.

The total number of attacks to try and break in and transfer money out of hacked customer accounts was up to 314 over the course of 2011, according to the Financial Services Information Sharing and Analysis Center (FS-ISAC), which released findings of its survey of 95 financial institutions and five service providers. That's an increase from 87 attacks against bank accounts in 2009 and 239 in 2010.

FS-ISAC is the group that coordinates on security issues with the Department of Homeland Security. The survey was conducted by the American Bankers Association.

The actual dollar losses taken by the financial institutions last year was $777,064, down from a high of $3.12 million in 2010. Dollar loss for customers was $489,672 in 2011, as compared with $1.16 million in 2010.
