Hackers have caused widespread disruption with a ransomware attack across Europe, hitting Ukraine especially hard.
A massive cyberattack swept the globe on Tuesday, hitting Ukraine particularly hard and causing chaos across much of Europe.
Companies and government agencies in Ukraine, Russian, UK, France, and Norway have reported ransomware demanding payment before unlocking their files.
It's unclear at the moment who's behind the attack, which harkens back to the WannaCry virus that affected 150 countries in May, or whether all of the reported issues are related.
The cyberattack continues to spread as more entities report being hit, but here's where we know it's struck so far:
UKRAINE: Banks, airports, government offices, power grid
Ukraine has been the hardest hit by the attack, which came one day before the country's Constitution Day. Company and government officials reported major disruption to the Ukrainian power grid, banks, government offices, and airports.
The radiation monitoring system in Chernobyl, the site of a nuclear disaster in 1986, was also affected, AFP reported. "Due to the temporary shutdown of the Windows system, the radiation monitoring of the industrial area is being done manually," the agency said on its website.
Anton Gerashchenko, an adviser to Ukraine's interior minister, wrote in a Facebook post that the attack was "the largest in the history of Ukraine."
RUSSIA: Banks, oil company, steelmaker
Russia's state-run Rosneft energy company also reported falling victim to hacking, but said oil production wasn't affected. The Russian steelmaker Evraz also said its information systems were under cyberattack, but its output wasn't impacted either.
The central bank of Russia said "computer attacks" had infected some IT systems of Russian banks. Reuters reported that all Russian branches of the Home Credit consumer lender are closed because of an attack, citing an employee of the lender's call center.
FRANCE: Saint Gobain
Saint Gobain, a French construction materials company, said it was also the victim of an attack, and a spokesman told Reuters that they were isolating computer systems in order to protect data.
UK: WPP
Britain's WPP, the world's largest advertising company, was also affected, the BBC reported.
NORWAY
Reuters reported that Norway's national security authority said a ransomware attack was taking place at one of the country's company, but didn't name which one.
GERMANY: Deutsche Post, Metro
German postal and logistics company Deutsche Post and wholesale retailer Metro both said their locations in Ukraine were part of the attack, and that they were assessing the impact.
Mondel?z International
The global food company Mondelez International said its employees were experiencing technical "difficulties in various geographies," but weren't sure if they too were the victim of a cyberattack.
"The Mondel?z International network is experiencing a global IT outage," the company said in a statement. "Our global special situations management team is in place, and they are working to resolve the situation as quickly as possible."
DENMARK: Maersk
The massive Danish shipping company A.P. Moller-Maersk, which is responsible for one out of seven containers shipped around the world, said every branch of its business was affected.
"We can confirm that Maersk IT systems are down across multiple sites and business units due to a cyber attack. We continue to assess the situation," the company wrote on its website. "The safety of our employees, our operations and customer's business is our top priority. We will update when we have more information."
UNITED STATES: Merck
