Yesterday, JPMorgan Chase & Co disclosed the scope of a data breach that impacts 83 million homes and small company accounts.
Hackers have taken the contact details for 76 million households-that’s practically 65% of all US households!-and 7 million smaller businesses: names, addresses, phone numbers, and email addresses. This is now the most significant data breach of all time. The data might also include former account holders, Reuters claims, not just current ones.
Chase doesn’t have proof that passwords, account numbers, user IDs, birthdates, or Social Security numbers had been compromised. And it has not seen any “unusual customer fraud” since the cyber-attack occurred in August.
In a customer press release on its site, Chase states:
Your money at JPMorgan Chase is safe:
- Unlike recent attacks on retailers, we have seen no unusual fraud activity related to this incident.
- Importantly, you are not liable for any unauthorized transaction on your account that you promptly alert us to.
We are very sorry that this happened and for any uncertainty this may cause you. We don’t believe that you need to change your password or account information. Click here for answers to questions you might have. As always, we recommend you use care with your accounts and information, as we describe in our Security Center.
We’re here to help
Attacks like these are frustrating. There are always lessons to be learned, and we will learn from this one and use that knowledge to make our defenses even stronger.
Chase customers must be looking for any fraudulent activity on their accounts and report it as quickly as you can.
Also, be sure to look out for phishing attacks, as the attackers have the information they need to pose as Chase. Remember to change your passwords and security questions and enable two-factor authentication.
