Regulator Tells Banks to Share Cyber Attack Information

A U.S. banking regulator told financial institutions to report cyber attacks to law enforcement and alert customers to their impact as new assaults targeted PNC Financial Services Group Inc. and other banks.

So-called denial-of-service attacks on websites may be used to distract bank personnel while intruders gain access to customers’ accounts, the U.S. Office of the Comptroller of the Currency warned in an alert distributed to bankers today. The attackers may also block customers from reporting frauds or prevent banks from telling them about it, the agency said. It didn’t identify the banks targeted.
