Following the worldwide WannaCry ransomware attack in May, a new wave of massive cyber attack has struck targets globally since Tuesday. Experts warn that the latest attack may grow even more and last longer.
MASSIVE ATTACK SPREADS WIDELY
Ukrainian authorities said Tuesday that a massive cyber attack has struck dozens of the country's government agencies, banks and private companies.
The websites of the Ukrainian cabinet and several ministries, the country's power distributor, the state railway operator, the largest airport, several banks, and a string of retail and fuel networks have been hit by the attack.
In addition, the radiation monitoring at the Chernobyl nuclear facility was reportedly affected by the attack.
Experts estimated that the attack, which has affected about 80 websites, was the largest in Ukraine's modern history.
Ukrainian Prime Minister Volodymyr Groysman has said that the information systems of Ukraine's critical infrastructure were not affected by the cyber attack.
"It was an unprecedented attack, but our IT-experts are doing their job and protecting critical infrastructure. Important systems have not been affected," Groysman wrote on Facebook.
According to Moscow-based cyber security company Group-IB laboratory, more than 80 companies in Russia and Ukraine came under the massive cyberattacks on Tuesday, including Russia's oil giant Rosneft.
The cyberattack targeted a number of oil, telecommunications and financial companies in Russia and Ukraine, blocking computers and demanding 300 U.S. dollars in Bitcoins, Group-IB told Russia's Prime news agency.
According to media reports, other big companies in Europe affected by the attack include Danish shipping conglomerate Maersk, British advertising agency WPP, Dutch shipping company TNT Express, and French construction and high-performance materials company Saint Gobain.
The cyber attack that had caused chaos in Europe also halted operations at the U.S. Port of Los Angeles' largest terminal on Tuesday.
The APM Terminals, operated by the shipping giant A.P. Moller-Maersk which handles about 16 percent of the world's shipping fleet, was shut down for hours on Tuesday as the company's IT systems were disturbed, according to the Los Angeles Daily News.
Just weeks ago the world was gripped by a mysterious computer virus known as WannaCry, which infected 300,000 computers in 150 countries and wreaked havoc on some of the world's largest companies.
