(Digiart2001 | jason.kuffer) No one is too big to get hacked — and that includes JPMorgan Chase and at least four other banks that were hit by hackers earlier this month. The FBI is investigating the blitzes, which seem to be sophisticated, coordinated cyberattacks that grabbed gigagbytes of data. According to sources cited by the New York Times, hackers grabbed information including checking and savings account information, but no one is quite clear on why the hackers went after the banks or what they’ll do with the information. The FBI and several security firms are reportedly trying to figure out whether the attacks were aimed at trying to reap financial reward or gather intelligence in an effort to spy on Western banks. Thus far, there are no numbers on how many, if any customers have been or will be affected, but one source says JPMorgan hasn’t seen fraud levels shoot up. “Companies of our size unfortunately experience cyberattacks nearly every day,” said a JPMorgan spokeswoman.
