NEW YORK: JPMorgan Chase said Thursday that it was cooperating with law-enforcement officials to determine the scale of reported cyber attacks against US financial institutions.
The largest US bank by assets said it was not seeing any sign of unusual fraud activity.
Late Wednesday, the Federal Bureau of Investigation said it was “working with the United States Secret Service to determine the scope of recently reported cyber attacks against several American financial institutions.”
According to people close to the situation, there has been no sign of hacking at three big New York banks, Goldman Sachs, Citigroup and Morgan Stanley.
The FBI declined to provide other details, but US media are reporting between two and five banks may have been targeted in coordinated cyber attacks that allowed hackers to steal several gigabytes of sensitive data.
