Two-Day Long DDoS Attack Breaches U.S. Utility

A US utility's website was taken offline in February by a two-day long distributed denial of service (DDoS) attack, according to security vendor Prolexic.

BankInfoSecurity reports there were no direct connections between the utility attack and those on financial institutions over the last six months but suggested that criminal hackers were broadening their attacks to include other aspects of the US infrastructure.

"Utilities are another vertical market that is likely to be victimized in the coming months as attackers look beyond daily targets like e-commerce and financial services," says Stuart Scholly, president at Prolexic, in a statement to BankInfoSecurity. "Attackers are targeting network infrastructures to cause collateral damage to other shared resources, so organizations must think about their different areas of vulnerability beyond website URLs."

Prolexic says during the 48-hour attack, some of the utility company's 1 million customers were not able to pay bills online or by phone, and employees were unable to receive external e-mails.
