A large-scale hacker attack on hundreds of corporate networks in the United States is spreading as far as Europe. Swedish supermarket chain Coop, one of the country’s largest grocery stores, closed its 800 branches on Saturday. The attack blocked checkout systems, a company spokeswoman said. State railways and a drugstore chain also reported disruptions.
Defense Minister Peter Hultqvist spoke of a very dangerous attack. “In another geopolitical situation, state actors could attack us in this way to cripple society and wreak havoc,” the minister said on television.
According to the TT news agency, the target of the attack in Sweden was software from the US supplier Kaseya used in many companies. He had already said on Friday that his VSA software may have been hacked. The tool is used by IT service providers to manage the IT systems of client companies. Kaseya recommended that VSA users shut down their servers immediately.
Hackers extorted millions of dollars from U.S. oil pipeline operator Colonial Pipeline
Eight IT service providers and around 200 corporate customers have been affected in the United States, according to US security service provider Huntress. “This is a huge and devastating attack on supply chains,” said Huntress chief executive John Hammond. The company suspects the REvil group of being behind the attack, the traces of which should lead to Russia. The FBI is already accusing REvil of attacking the world’s largest meat company, JBS, in which hackers extorted eleven million dollars.
In the United States, the state and businesses are battling a wave of attacks with ransomware. The data of the attacked systems is encrypted. For a reissue, hackers demand payments in cryptocurrency. Hackers also extorted millions of dollars from the US oil pipeline operator Colonial Pipeline. An attack on US software maker SolarWinds, which affected thousands of users, also caused a stir.
