JP Morgan breach heightens data security doubts

LOS ANGELES (AP) – New details on a cyberattack against JPMorgan Chase & Co.’s computer servers this summer add to increasing doubts over the security of consumer data kept by lenders, retailers and others.

The New York-based bank disclosed Thursday that the breach compromised customer information pertaining to roughly 76 million households and seven million small businesses.

Among the customer data stolen were names, addresses, phone numbers and email addresses, though only customers who use the websites Chase.com and JPMorganOnline and the apps ChaseMobile and JPMorgan Mobile were affected, the bank said.

JPMorgan stressed that there’s no evidence that the data breach included account numbers, passwords, Social Security numbers or dates of birth. It also noted that it has not seen any unusual customer fraud stemming from the data breach.

The server breach follows data thefts that have hit financial firms and major retailers this year, adding to consumer concerns over the risk of identity theft and fraud.

The Chase heist is even more disturbing than the recent retail breaches because banks are supposed to have fortress-like protection against intruders, said Gartner security analyst Avivah Litan.

“This is really a slap in the face of the American financial services system,” Litan said. “Honestly, this is a crisis point.”

JPMorgan Chase, the nation’s biggest bank by assets, has been working with law enforcement officials to investigate the cyberattack.
