Algoma Power's warning of a ransomware attack against its billing contractor.
FortisOntario - which owns Algoma Power - says it was made aware earlier this week of "a possible ransomware attack on a third-party contractor that prints bills and provides certain electronic billing services for customers of Canadian Niagara Power, Eastern Ontario Power, Algoma Power, and Cornwall Electric".
It adds it isn't aware of any personal information of customers being "inappropriately accessed", though it assures all that could be accessed would be customer names, addresses, electrical consumption, and other information on bills or used for electronic billing services - and no additional customer information like banking information was accessed.
The company further notes it has "engaged an internal team to investigate", and is working with the contractor to assess the situation.
