It is starting to look like the hack of JPMorgan Chase was one of the biggest in history. Names, addresses, phone numbers and email addresses of the holders of some 83 million households and small business accounts were nicked by hackers.
The bank revealed the scope of the previously disclosed breach on Thursday, saying that there was no evidence that account numbers, passwords, user IDs, birth dates or Social Security numbers had been stolen. However so far it seems that the hackers have not used the data JPMorgan Chase said that it added that it has not seen "unusual customer fraud" related to the attack which exposed contact information for 76 million households and 7 million small businesses.
Security experts outside of the bank warned that the breach could result in an increase in crime as scammers will likely attempt to use the stolen information to engage in various types of fraud. JPMorgan advised customers on its website that it does not believe they need to change their passwords or account information.
Company spokeswoman Patricia Wexler said that the bank is not offering credit monitoring to its customers because no financial information, account data or personally identifiable information was compromised.
