Seventy-six million account details stolen in JP Morgan attack
Scale of hacking theft in August confirmed to be far above original estimates
JP Morgan has confirmed in regulatory filing that 76 million of its private customers, and seven million business customers, had their details stolen in a hacking attack.
The bank, the largest in the US, had announced in August that it had been the victim of a cyber attack, but it was thought that only around one million accounts had been effected.
The bank has now revealed in a filing to the US Securities and Exchange Commission that a huge number of customer account data was stolen.
JP Morgan told the SEC that only account holders names and addresses were stolen, not critical information such as account numbers or passwords, and that it had not seen any fraudulent activity related to the incident.
Initial reports said that Russian hackers were behind the attack on JP Morgan, but this has not been confirmed.
