"Ransomware Attack Forces Canadian Mining Company to Shut Down Mill"

Canadian Copper Mountain Mining Corporation (CMMC) recently shut down its mill after falling victim to a ransomware attack.  Listed on the Toronto Stock Exchange, the firm owns most of the Copper Mountain mine.  Located in southern British Columbia, the mine produces an average of 100 million pounds of copper equivalent per year.  The company fell victim to a ransomware attack on December 27, 2022.  Because of the ransomware attack, the company has isolated operations, switched to manual processes, where possible, and the mill has been preventatively shut down to determine the effect on its control system.  The company stated that it implemented risk management systems and protocols immediately after discovering the cyberattack and that the relevant authorities are assisting with the investigation.  The company noted that there had been no safety or environmental incidents due to the attack.  The company has not yet shared information on the type of ransomware used in the attack nor how the attackers breached its systems.  According to a BleepingComputer report,  stolen credentials might have been used for intrusion.  Earlier in December, credentials belonging to a CMMC employee account were being offered for sale on a hacker portal.
