New major cyberattack hits international firms

A major cyberattack has unfolded, striking banks, corporations and infrastructure in Ukraine and Russia before spreading to western Europe and then the United States.

Experts say the virus is a modified version of the so-called Petya ransomware, which hit last year and demanded money from victims in exchange for their data.

A similar virus called WannaCry infected more than 200,000 computers in more than 150 countries last month.

Following is a list of companies and organisations which say they have been a victim of the latest attack:

• Ukraine’s central bank, the National Bank of Ukraine

• Ukrainian bank Oschadbank

• Ukrainian delivery service company Nova Poshta

• Russian state oil giant Rosneft

• Kyivenergo, Kiev power company

• Radiation monitoring system at Chernobyl

• Website of Kiev’s Boryspil international airport

• Danish sea transport company Maersk

• British advertising giant WPP

• French industrial group Saint-Gobain

• US pharmaceutical giant Merck
