This summer's attack on JPMorgan Chase's computer network might have allowed hackers to detect subtle vulnerabilities they could return to and exploit in the future, The New York Times reported this past week.
The hackers had access to the bank's servers for more than two months, and could have figured out how individual computers work and discover their vulnerabilities. As a result, the bank might face obstacles in finding every vulnerability and ensuring its systems are protected from future attacks.
The hackers didn't access account holders' Social Security numbers or financial information, but they did view account data of about one million customers that could have included names, addresses and phone numbers.
Sources familiar with the case think the attack could have been coordinated or put together with assistance from a foreign government. The hackers are thought to be Russian.
