JPMorgan Says It’s Unaware of Any New Hacker Attack on Systems

JPMorgan Chase & Co. said it’s not aware of a new attack on its computer systems after the New York Times reported the bank was scrambling for the second time in three months to contain fallout from a security breach.

“We are not aware of any new attack,” Patricia Wexler, a spokeswoman for the New York-based bank, said by e-mail.

JPMorgan recently found that hackers linked to Italy or southern Europe accessed some of its servers, the Times reported today, citing unidentified people with knowledge of the investigation. The discovery follows an attack uncovered months ago and suggests it was more extensive than previously thought, the newspaper said. Leaders at the bank have been working to assess the extent of the attack, the publication cited two executives as saying.

The Times corrected an earlier version of its story to remove a characterization of the recent discovery as a second breach. Wexler called that report false.

JPMorgan, the biggest U.S. bank, had gigabytes of data, including customer-account information, siphoned by hackers in an attack that lasted months, people familiar with that incident told Bloomberg News in August, shortly after its detection. Investigators in that case tracked stolen files to a Russian data center, the people said.

Before it's here, it's on the Bloomberg Terminal.
