The Ontario Progressive Conservative Party’s internal database was hacked. The database comprised names, phone numbers and other personal information of over a million eligible voters in the province, the party supporters, donors and campaign volunteers. The Constituent Information Management System (CIMS)was breached before Christmas using a ransomware virus. The attack was not the first on the system. The attack used to access and encrypt four servers. The affected servers immediately quarantined and restored pre-attack server backups within the same day. Their logs indicated that no data was stolen from the Party.
