Recent victims have included large corporations such as retailer London Drugs, as well as the City of Hamilton, Ont., and the government of Newfoundland and Labrador.

Retailer London Drugs says cybercriminals who stole files from its corporate head office last month have released some of the data after it refused to pay a ransom.

A global ransomware operator issued an apology and offered to unlock the data targeted in a ransomware attack on Toronto’s Hospital for Sick Children, a move cybersecurity experts say is rare, if not unprecedented, for the infamous group. 

A shadowy group of cyber criminals that attacked a prominent nursing organization and Canadian Tire store has successfully targeted other companies with clients in governments, health care, insurance and other sectors.
