JP Morgan Chase & Co plus at least four other financial institutions have reportedly come under attack by hackers. According to a quartet of people familiar with the investigation, the possibility exists that gigabytes of customer data, including banking information, may have been stolen by the assailants with a "zero-day" attack, who may to be linked to Russian state-sponsored hackers.
The US Federal Bureau of Investigation (FBI) and US Secret Service are working in parallel to investigate the intrusions. Bloomberg claims that the US National Security Agency is working with the pair as well. FBI spokesman J. Peter Donald confirmed the involvement of the Secret Service in the matter, and will work to determine the magnitude of the "recently reported cyber attacks against several American financial institutions."
JP Morgan launched an internal investigation after malware was discovered internally. The bank has yet to determine the severity of the malware, and no formal issuances of data loss have been given to customers as of yet.
The New York Times reports that the assailants have been "siphoning off gigabytes of data including checking and savins account information" in this attack, and others that took place earlier in the month. Other sources note that they can't confirm the Times' claim of the data pilferage.
When asked about the attacks and potential thefts, JPMorgan spokeswoman Patricia Wexler stated that "companies of our size unfortunately experience cyberattacks nearly every day. We have multiple layers of defense to counteract any threats and constantly monitor fraud levels." The bank claims to not be seeing enhanced fraud activity.
