In 48 hours, several Chase accounts have been compromised across Indianapolis leaving the company's security team investigating the source.
"This is the first I've heard of it, this is the first I've heard of it, I didn't know anything about that," said Gloria Jones, a Chase customer.
Fox 59 News confirms the fraud is happening.
According to Nancy Norris, a Chase spokesperson, "Over the last couple of days the fraud department has detected fraudulent activity on several customers' accounts in Indianapolis."
One customer who wanted to remain anonymous says his account was "wiped out."
"At this time we don't know whether the debit card information was compromised by a skimming device either on an ATM or a retailer," said Norris.
A Chase security team is investigating whether the breach is happening at ATMs, through skimming devices, which lift banking information from debit and credit cards or if the breach is happening online.
"It's when you click that link and it takes you to a website and you enter in your information, at that point it's too late," said Daniel Curry with Indy's Computer Geek.
Curry says it's not just fraudulent emails consumers should monitor.
"Email is one way that people can collect this information. Another way is through your Facebook account and your Twitter account. People will just watch for you putting in personal details that they can then use to try a child's birth date, a dog or favorite animal, pet's name. If you use those for password, you've just shared your password with the world," said Curry.
Chase says customers affected were contacted and asked to fill out an affidavit of fraud at their neighborhood Chase branch.
According to Norris, "No Chase customer has loss anything. Chase has detected the fraud. We have notified those customers who were affected and their accounts have been made whole."
