JP Morgan reported a security breach this past summer, and now we’re finally getting reports from the bank showing just how massive the cyberattack was.
Hackers compromised the accounts of more than 76 million households and 7 million small businesses. The more than 80 million total individuals impacted by the cyberattack appears to be one of the largest security failures ever.
The scale of the attack, which happened in August, was finally, nearly two months later, detailed in a JP Morgan securities filing released on Thursday. JP Morgan was one of seven banks that fell victim to hackers last summer.
There is some good news. JP Morgan reports it hasn’t seen any fraudulent activity on the accounts or found any evidence that the criminals were able to capture account numbers, social security numbers or dates of birth, some of the most sensitive information.
“The Firm continues to vigilantly monitor the situation and is continuing to investigate the matter,” the bank said in its filing.
Authorities aren’t sure who is behind the attacks, but Trend Micro saw some evidence in an uptick in hacking activity against U.S. and EU banks coming from Russia.
If you think your account might have been compromised in this or any other cyberattack, here are a few things to keep in mind:
- Monitor your statements for weird activity.
- Keep an eye out for updates and instructions from your bank.
- If anyone contacts you asking for sensitive information like social security or account numbers, decline, and call the number you have on file to verify it’s authentic.
