Huge natural gas producer severs Website, email after malware attack

A liquefied natural gas plant in operation.

One of the world’s biggest producers of liquefied natural gas has been hit by a malware attack that has taken down its website and e-mail servers. This is the second documented computer attack to hit a large energy company this month.

Officials with Qatar-based RasGas first identified an “unknown virus” on Monday and took their RasGas.com website and e-mail servers offline in response, Bloomberg News and other news agencies reported on Thursday morning, citing company representatives.

A joint venture between Qatar Petroleum and ExxonMobil, RasGas exports about 36.3 million tons of liquefied natural gas per year.

News of the attack comes four days after Saudi Aramco, the world’s largest oil producer, confirmed it was the victim of a separate malware attack that took down 30,000 workstations.

Oil production wasn’t affected, company officials have said.
