In a cybersecurity incident on January 1, 2025, Kingston Police (KP) suffered a breach where a threat actor accessed their systems using compromised account credentials via the VPN application. The attack resulted in the encryption and extraction of 160 GB of data, affecting approximately 345,000 documents, including sensitive personal information related to criminal court records, traffic tickets, and bail hearings. The breach impacted around 51,000 individuals with court information and up to 100,000 with provincial offence ticket data.
