A ransomware attack on a US IT firm Kaseya ​potentially targeted 1,000 businesses, with one of Sweden's biggest supermarket chains revealing it had to temporarily close around 800 stores after losing access to its checkouts.

Russian-based hackers have been blamed for a string of ransomware attacks, and US President Joe Biden recently raised the threat in talks with Russian counterpart Vladimir Putin.

The IT company targeted, Kaseya, said Friday evening it had limited the attack to "a very small percentage of our customers" who use its signature VSA software -- "currently estimated at fewer than 40 worldwide." Brett Callow, an analyst for cybersecurity company Emsisoft, said it remained unknown how many companies were affected and said the scale of attack could be "without precedent."

It also "notified our on-premises customers via email, in-product notes, and phone to shut down their VSA servers to prevent them from being compromised." REvil was also, according to the FBI, behind last month's attack on JBS, one of the world's biggest meat processors, which ended with the Brazil-based company paying bitcoin worth $11 million to the hackers.The UN Security Council this week held its first formal public meeting on cybersecurity, addressing the growing threat of hacks to countries' key infrastructure.

"In this case, they attacked a company that provides software for managing data systems, allowing them to simultaneously target several dozen -- possibly even hundreds -- of companies," he said.
