MOSCOW/KIEV/WASHINGTON (Reuters) – A major global cyber attack on Tuesday disrupted computers at Russia’s biggest oil company, Ukrainian banks and multinational firms with a virus similar to the ransomware that last month infected more than 300,000 computers.
The rapidly spreading cyber extortion campaign underscored growing concerns that businesses have failed to secure their networks from increasingly aggressive hackers, who have shown they are capable of shutting down critical infrastructure and crippling corporate and government networks.
It included code known as “Eternal Blue,” which cyber security experts widely believe was stolen from the U.S. National Security Agency and was also used in last month’s ransomware attack, named “WannaCry.”
“Cyber attacks can simply destroy us,” said Kevin Johnson, chief executive of cyber security firm Secure Ideas. “Companies are just not doing what they are supposed to do to fix the problem.”
The ransomware virus crippled computers running Microsoft Corp’s
Microsoft said the virus could spread through a flaw that was patched in a security update in March.
“We are continuing to investigate and will take appropriate action to protect customers,” a spokesman for the company said, adding that Microsoft antivirus software detects and removes it.
Some 2,000 attacks were observed as of midday in New York on Tuesday, according to Kaspersky Lab. Russia and Ukraine were most affected, with other victims spread across countries including Britain, France, Germany, Italy, Poland and the United States, the security software maker said.
Security experts said they expected the impact to be smaller than WannaCry since many computers had been patched with Windows updates in the wake of WannaCry last month to protect them against attacks using Eternal Blue code.
Still, the attack could be more dangerous than traditional strains of ransomware because it makes computers unresponsive and unable to reboot, Juniper Networks
Researchers said the attack may have borrowed malware code used in earlier ransomware campaigns known as “Petya” and “GoldenEye.”
Following last month’s attack, governments, security firms and industrial groups aggressively advised businesses and consumers to make sure all their computers were updated with Microsoft patches to defend against the threat.
The U.S. Department of Homeland Security said it was monitoring the attacks and coordinating with other countries. It advised victims not to pay the extortion, saying that doing so does not guarantee access will be restored.
The NSA did not respond to a request for comment. The spy agency has not publicly said whether it built Eternal Blue and other hacking tools leaked online by an entity known as Shadow Brokers.
Several private security experts have said they believe Shadow Brokers is tied to the Russian government, and that the North Korean government was behind WannaCry. Both countries’ governments deny charges they are involved in hacking.
‘DON’T WASTE YOUR TIME’
The first attacks were reported from Russia and Ukraine.
Ukrainian Deputy Prime Minister Pavlo Rozenko said the government’s computer network went down and the central bank reported disruption to operations at banks and firms including the state power distributor.
Danish shipping giant A.P. Moller-Maersk
A Ukrainian media company said its computers were blocked and it was asked to pay $300 in the crypto-currency bitcoin to regain access.
“Perhaps you are busy looking for a way to recover your files, but don’t waste your time. Nobody can recover your files without our decryption service,” the message said, according to a screenshot posted on Ukraine’s Channel 24.
Russia’s central bank said there were isolated cases of lenders’ IT systems being infected. One consumer lender, Home Credit, had to suspend client operations.
Other companies that identified themselves as victims included French construction materials firm Saint Gobain
India-based employees at Beiersdorf, makers of Nivea skin care products, and Reckitt Benckiser
Western Pennsylvania’s Heritage Valley Health System’s entire network was shut down by a cyber attack on Tuesday, according to local media reports.
Last’s month’s fast-spreading WannaCry ransomware attack was crippled after a 22-year-old British security researcher Marcus Hutchins created a so-called “kill-switch” that experts hailed as the decisive step in slowing the attack.
Security experts said they did not believe that the ransomware released on Tuesday had a kill switch, meaning that it might be harder to stop.
Cyber intelligence firm Flashpoint said it believed the outbreak began in Ukraine, where attackers loaded the ransomware onto computers when they requested updates of a widely used accounting software programme.
An adviser to Ukraine’s interior minister said earlier in the day that the virus got into computer systems via “phishing” emails written in Russian and Ukrainian designed to lure employees into opening them.
According to the state security agency, the emails contained infected Word documents or PDF files as attachments.
