France's G20 plans targeted in cyberattack: Source

France's finance ministry was subject to a cyberattack on some 150 computers in December targeting information related to its presidency of the Group of 20 nations, a source close to the minister confirmed on Monday.

The source said that security services had taken immediate steps to stop the attacks, which took place shortly after France started its presidency of the group of rich and developing nations in November.

"It was detected towards the end of last year, in December," said the source. "Several computers in (the finance ministry at) Bercy, in particular those working on the G20 -- around 150 computers -- were subject to an attack."

However, he could not confirm a report on the website of Paris Match that some of the information had been redirected towards Chinese websites.
