The United Nations confirmed reports that activist group Anonymous leaked personal data from some 1,400 people using its climate website

The United Nations confirmed Thursday reports that activist group Anonymous leaked personal data from some 1,400 people using its climate website, as the world gathered in Paris to craft a climate rescue pact.

"I can confirm there was a hacking incident earlier this week and that has been handled by the conference's IT security experts," said UN climate secretariat spokesman Nick Nuttall, who declined to make any further comment.

According to news site Hackread: "The hacktivist group Anonymous breached into the website of United Nations Framework Convention on Climate Change (UNFCCC) and leaked a trove of personal information of 1,415 officials."

It said: "Anonymous is protesting against the arrests of peaceful protesters marching against the Climate-related policies in the country's (France's) capital," the site said.

According to a list shown to AFP, the information included emails and encrypted passwords.

A member of the French delegation to the Paris climate talks said she was a victim of the hack.

"I changed my password and everything has been normal since," she said.
