The Green Bay Packers are warning fans of a serious data breach involving their official online retail store. According to a message to customers, threat actors infiltrated the website late last year, injecting a malicious card skimmer script designed to steal customers' personal and payment information during transactions on packersproshop.com.

The Packers said Tuesday a data breach affected a limited number of people who made credit card transactions during the period.

If you purchased anything from the Packers Pro Shop website in the fall, you may be receiving a notice in the mail. The team reported Tuesday of a data breach that could leak the personal data of multiple fans.

The Green Bay Packers Pro Shop website was hit by hackers recently, the team confirmed in a statement sent to NBC 26 on Tuesday.
