Anonymous Cambodia, the local arm of the notorious global hacking collective, claimed yesterday to have leaked previously undisclosed voter names from the National Election Committee’s mainframes, which they said demonstrated illegal registrants.

The information was released to the public directly from a hacked page of the government’s voter list website.

“[We have] obtained backup documents that ‘they’ do not want you to see, we have found them, and are giving them to you. These … documents prove that the NEC is allowing the illegal Vietnamese migrants … to vote,” reads the statement posted to the voter list site.

A group member using the pseudonym Black Cyber told the Post on Sunday that Anonymous had stolen over two gigabytes of data from NEC servers as part of what they have dubbed “Operation Radar”.

In an email yesterday, Black Cyber said that thousands of names were in the process of being leaked.

“We bring this to you, so that you know just how little rights you have.… So feel free to download these documents. … Let these people know that we will not be silenced,” the group’s statement says.

NEC secretary-general Tep Nytha said yesterday that only one legal voter list existed and called the Anonymous list “a fake document”.

“I think that what they want to do is destroy the national election,” he said.

“Even though there are foreign names, they all have the legal documents … so we had to process them as voters,” he added.

Last week, the NEC said an independent audit of the nation’s voter lists found only three per cent of eligible voters names checked could not be accounted for.

An earlier survey from the National Democratic Institute found a 9.4 per cent rate of missing names.

Anonymous Cambodia yesterday also announced its plans to infect the NEC’s computer network with a virus and uploaded games of snake and tic-tac-toe onto other hacked pages of the voter list site.

Yesterday’s hacking followed Anonymous’ distributed denial of service (DDoS) attack against the NEC website on July 7, which took the site offline for about 12 hours.
