MEDFORD, MA — ParkMobile, the company that operates Medford's mobile parking app, announced in March it was investigating a cybersecurity incident linked to a vulnerability in a third-party software.

The company's investigation into the breach found that it included basic user information, such as license plate numbers, email addresses, phone numbers and vehicle nicknames, if provided. In some cases, mailing addresses were affected.

The breach did not include credit card information or data related to a user's parking transaction history. Encrypted passwords were accessed, but not the encryption keys required to read them.

ParkMobile completed its investigation April 15 after notifying law enforcement and eliminating the third-party vulnerability. The company encourages users to change their password in the "settings" section of the ParkMobile app or by clicking this link.
