Most of one of Sweden's leading supermarket chains' 800 shops remained closed on Monday, three days after they were indirectly affected by the cyberattack targeting US company Kaseya.
On Friday, a hacking attack indirectly hit the supermarket chain, paralysing all its cash registers and forcing the company to temporarily close nearly all its shops across the country.
Subcontractor Visma Esscom, where the problem originated, said it was linked to a major cyber attack on Friday on the US company Kaseya.
Swedish Defence Minister Peter Hultqvist said over the weekend that he was concerned that the attack demonstrated the vulnerability of modern society where a cyberattack could impact "Food security and other basic securities."
Ransomware attacks typically involve locking away data in systems using encryption, making companies pay to regain access.
In recent weeks, such attacks have hit oil pipelines, health services and major firms, and made it onto the agenda of US President Joe Biden's June meeting with Russian counterpart Vladimir Putin.
