Cyber attack against US IT provider forces Swedish chain to close 800 stores

The Swedish Coop grocery store chain closed all its 800 stores after a cyber attack hijacked the technology management software used by it. The company said a tool used to remotely update its checkout tills was affected by the attack, meaning payments could not be taken.

The Swedish Coop grocery store chain closed all its 800 stores on Saturday after a ransomware attack on an American IT provider left it unable to operate its cash registers. Hundreds of American businesses were hit on Friday by an unusually sophisticated attack that hijacked widely used technology management software from a Miami-based supplier called Kaseya.
