The names and email addresses of 174,000 members, donors, and customers of camps and birthday parties at the Ontario Science Centre were exposed in August, according to the company that does email blasts for the provincially owned tourist attraction.
The breach was made public Monday evening when the Science Centre alerted its newsletter subscribers, although the Science Centre has been aware of the breach since August 16 when they were alerted by Campaigner, an Ottawa-based firm the Science Centre uses for email campaigns.
The alert sent to those affected stated that no other personal information was exposed.
According to the investigation by Campaigner, the breach occurred when a former employee’s credentials were used between July 23 and August 7 to access and download data from the Science Centre account that houses data related to mailings, newsletters, and invitations.
