A large-scale hacker attack on hundreds of corporate networks in the United States has spread to Europe. Swedish supermarket chain Coop, one of the country’s largest grocery stores, closed all of its 800 branches on Saturday. A company spokeswoman said the attack shut down cash register systems. State railways and a pharmacy chain have also reported disruptions.
Defense Minister Peter Hultqvist spoke of a very serious attack. “In another geopolitical situation, state representatives can attack us in this way to paralyze society and create chaos,” the minister said on television.
According to the news agency “TT”, the target of the attack in Sweden was software from the American company “Cassia”, which is 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 computer systems of corporate clients. Kaseya recommended that VSA users shut down their servers immediately.
Hackers extorted millions of dollars from Colonial Pipeline, the operator of US oil pipelines
According to US security service provider Huntress, eight IT service providers and nearly 200 corporate customers in the US have been affected. “This is a massive and devastating attack on supply chains,” said Huntress Director John Hammond. The company suspects that the Revell group is behind the attack, the effects of which should lead to Russia. The FBI has already blamed REvil for an attack on the world’s largest meat company, JBS, in which hackers extorted $11 million.
In the United States, the state and companies are fighting a wave of attacks with extortion software (ransomware). The data of the systems that have been attacked is encrypted. For re-release, hackers demand payments in cryptocurrency. The hackers also extorted millions of dollars from the US oil pipeline operator Colonial Pipeline. An attack on the US software manufacturer SolarWinds, which affected thousands of users, also caused an uproar.
