That has magnified the attackвЂ™s severity, said John Hammond, a researcher at the cybersecurity company Huntress Labs. The company urged customers that use its systems management platform, called VSA, to immediately shut down their servers to avoid the possibility of being compromised by attackers. The attack became public on Friday, when Kaseya said that it was investigating the possibility that it had been the victim of a cyberattack.

In previous attacks, REvil was known to break in through a combination of phishing, stolen passwords or a lack of multifactor authentication.Дutch researchers said they had reported the vulnerability to Kaseya, but the company was still working on a patch when it was breached and its software updates were compromised, according to people briefed on the timeline. Beaumont said the attack marked a serious escalation in the tactics of ransomware gangs.

In the meantime, cybercriminals and spies can use the vulnerability to wreak havoc. Kaseya was initially breached through a previously unknown vulnerability in its systems - known as a вЂњzero dayвЂќ because when such vulnerabilities are discovered, software makers have zero days to fix it. Instead of getting KaseyaвЂ™s latest update, they received REvilвЂ™s ransomware. Victims of the breach were hit through a Kaseya software update, Kevin Beaumont, a threat researcher, said. вЂњThe initial thinking was it was not the Russian government, but weвЂ™re not sure yet,вЂќ he said. He said he had directed the вЂњfull resources of the federal governmentвЂќ to investigate. Asked about the cyberattack after he landed in Michigan on Saturday on a trip to celebrate Covid-19вЂ™s retreat in the United States, President Biden said he had been delayed in getting off the plane because he was being briefed about the attack.
