He says that despite its appearance as a ransomware hack, he believes the attack is actually the work of Russian agents who are waging a type of hybrid warfare to try to destabilize Ukraine.
"We can confirm that Maersk IT systems are down across multiple sites and business units due to a cyberattack", employees said in a statement.
"As a result of these cyberattacks, banks experience difficulty in servicing customers and performing banking operations". Experts are also not confident about resolving the issue either; they don't yet know whether it would be possible to mitigate the effects of the attack.
The malware is being called "Petya" - but we'll note that in the security community, there is a debate over whether the ransomware is brand new, or if it's a variant of Petya that's been enhanced to make it harder to stop.
Ukraine's prime minister says that a cyberattack affecting his country is "unprecedented", but "vital systems haven't been affected".
As reports of the attack spread quickly, the Ukrainian government said that several of its ministries, local banks and metro systems had been affected. 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.
Department of Homeland Security spokesman Scott McConnell refused to explain if U.S. firms or infrastructure have been affected by the cyber attacks, but he said that the government is in communication with its global partners and is ready to provide help to anyone who requests it, Efe news reported. In Russia, the malware hit companies such as Mars, Nivea and Mondelez International, according to the Tass news agency.
A Ukrainian military intelligence officer was killed by a bomb under his vehicle while he was driving through the country's capital, Kiev, officials say.
The Chernobyl nuclear power plant was also hit by the cyber attack, according to a Ukrainian federal agency.
Company and government officials reported serious intrusions at the Ukrainian power grid, banks and government offices, where one senior official posted a photo of a darkened computer screen and the words, "the whole network is down". Its Microsoft Windows systems were temporarily disconnected, and radiation monitoring in the area of the industrial site is being carried out manually, it said.
Ransomware is a computer virus that encrypts all the files on an infected computer and requires the victim to pay to regain access to their data.
