One of the city’s best-known social clubs says it is working with the FBI to investigate a security breach involving guests’ credit card information.

Earlier this year, the Union League Club of Chicago learned that one of its employees was using computer software to access credit card information, among other things, according to a statement from the club Tuesday.

“The information potentially compromised involves data found in the magnetic stripe of payment cards, which includes the cardholder name, card number and expiration date,” according to the statement, which was posted on the club’s website.

So far, the investigation hasn’t found any evidence the employee misused the credit card information, the club said.

The club suggests that anyone who used a credit card there between Dec. 10, 2015 and March 2, 2016, should closely review account statements for any unauthorized actively.

The club has since removed the software used to access the credit card information. The club has also beefed up “technical safeguards,” limiting employee access to guests’ personal information, according to the statement.

An FBI spokesman at the Chicago office had no comment Tuesday.

For more information, call the club at 1-844-812-9518.
