ParkMobile Breach Exposes License Plate Data, Mobile Numbers of 21M Users

Someone is selling account information for 21 million customers of ParkMobile, a mobile parking app that’s popular in North America. The stolen data includes customer email addresses, dates of birth, phone numbers, license plate numbers, hashed passwords and mailing addresses.



KrebsOnSecurity first heard about the breach from Gemini Advisory, a New York City based threat intelligence firm that keeps a close eye on the cybercrime forums. Gemini shared a new sales thread on a Russian-language crime forum that included my ParkMobile account information in the accompanying screenshot of the stolen data.


Included in the data were my email address and phone number, as well as license plate numbers for four different vehicles we have used over the past decade.


Asked about the sales thread, Atlanta-based ParkMobile said the company published a notification on Mar. 26 about “a cybersecurity incident linked to a vulnerability in a third-party software that we use.”


“In response, we immediately launched an investigation with the assistance of a leading cybersecurity firm to address the incident,” the notice reads. “Out of an abundance of caution, we have also notified the appropriate law enforcement authorities. The investigation is ongoing, and we are limited in the details we can provide at this time.”


The statement continues: “Our investigation indicates that no sensitive data or Payment Card Information, which we encrypt, was affected. Meanwhile, we have taken additional precautionary steps since learning of the incident, including eliminating the third-party vulnerability, maintaining our security, and continuing to monitor our systems.”
