A major cyber attack, believed to have first struck Ukraine, caused havoc around the world on Wednesday, crippling computers or halting operations at port operator Maersk, a Cadbury chocolate plant in Australia and the property arm of French bank BNP Paribas.
Russiaโs biggest oil company, Ukrainian banks and multinational firms were among those hit on Tuesday by the cyber extortion campaign, which has underscored growing concerns that businesses have failed to secure their networks from increasingly aggressive hackers.
The rapidly spreading computer worm appeared to be a variant of an existing ransomware family known as Petya which also has borrowed key features from last monthโs ransomware attack, named โWannaCryโ.
ESET, an anti-virus vendor based in Bratislava, said 80 per cent of all infections from the new attack detected among its global customer base were in Ukraine, with Italy second hardest hit at around 10 percent. Several of the international firms hit had operations in Ukraine.
Shipping giant AP Moller-Maersk, which handles one in seven containers shipped worldwide and has a logistics unit in Ukraine, is not able to process new orders after being hit by the attack on Tuesday, it told Reuters.
โRight now, at this hour, weโre not able to take new orders,โ Maersk Line Chief Commercial Officer Vincent Clerc said in a telephone interview on Wednesday.
BNP Paribas Real Estate, which provides property and investment management services, confirmed it had been hit but declined to specify how widely it had affected its business. It employed nearly 3,500 staff in 16 countries as of last year.
โThe international cyber attack hit our non-bank subsidiary, Real Estate. The necessary measures have been taken to rapidly contain the attack,โ the bank told Reuters on Wednesday, after a person familiar with the matter had said that some staff computers were blocked on Tuesday due to the incident.
Production at the Cadbury factory on the island state of Tasmania ground to a halt late on Tuesday after computer systems went down, said Australian Manufacturing and Workers Union state secretary John Short.
Russiaโs Rosneft, one of the worldโs biggest crude producers by volume, said on Tuesday its systems had suffered โserious consequencesโ but said oil production had not been affected because it switched over to backup systems.
The virus crippled computers running Microsoft Corpโs Windows by encrypting hard drives and overwriting files, then demanded $300 in bitcoin payments to restore access.
Several security experts questioned whether the effort to extort victims with computers hit by the virus was the main goal, or whether the unknown hackers behind the attack could have other motives.
