Evertec (EVTC) said Tuesday a cybersecurity incident has impacted its financial institution clients in Puerto Rico and their respective customers last month.

The company said an unauthorized party obtained, through a third-party support platform, some of its financial institution clients' information, including transaction records and payment card numbers of some customers.

The company said it has taken steps to contain the incident and secure its systems, and believes that the unauthorized party no longer has access to the third-party support platform.

Evertec said it notified federal law enforcement authorities and engaged external cybersecurity experts to assist in the investigation and response efforts.
