Stockholm, Sweden: After a cyberattack stopped access to its checkouts, one of Sweden’s largest grocery chains said Saturday that it had to temporarily close roughly 800 stores across the country.
“One of our subcontractors was hit by a digital attack, and that’s why our checkouts aren’t working any more,” Coop Sweden, which accounts for around 20 percent of the sector, said in a statement.
“We regret the situation and will do all we can to reopen swiftly,” the cooperative added.
Beginning on Friday evening, Coop Sweden did not name the subcontractor or reveal the hacking method employed against it.
However, the incident comes amid a worldwide wave of ransomware attacks, particularly in the United States.
Ransomware attacks often encrypt data in networks and demand that businesses pay a ransom to recover access.
According to security firm Emsisoft, hackers used similar software to extort at least $18 billion last year.
After dozens of servers running Kaseya’s VSA platform were infected with ransomware on Friday, the company asked clients to shut them down.
Such attacks have targeted oil pipelines, health facilities, and large corporations in recent weeks, and have made it into US President Joe Biden’s June meeting with Russian counterpart Vladimir Putin’s agenda.
