Retaliating against the recent arrests of four members, “hacktivist” group Anonymous Cambodia ramped up its revenge campaign this weekend, hacking into nine different websites, according to the group’s Facebook page.

The slew of cyberattacks included the Royal Gendarmerie website, the Ministry of National Defense website and the government’s Computer Emergency Response Team.

“Free our comrades!” the hacking group demanded in a statement yesterday. “We are not a small group of people residing in Cambodia for you to ignore, we are [an] organised, globally active collective of like-minded individuals and our message to you is clear, we declare war . . . ”

The local wing of the international hacking association vowed to “topple the government of Cambodia” after an eight-month investigation by the National Police and the US Federal Bureau of Investigation led to the arrest of two 21-year-old members last month.

On Thursday, two more hackers were arrested after they shut down the Anti-Corruption Unit’s website for more than two hours on April 29.

A police statement named SETEC students Bun King Mongkolpanha and Chu Songheng as the suspects arrested early in April, but ACU president Om Yentieng declined to identify the two recently arrested members.

“They used the name ‘Game-Over-xX23xX’ to attack and destroy ACU’s data and website,” he said.

The suspects are being held at the Ministry of Interior for further questioning, according to Chhay Sinarith, director of the ministry’s internal security department.

Anonymous also hacked the military police’s website on Friday, spokesman Kheng Tito said.

“I don’t think their group has many people, and we will wipe it out,” he said.

No one has yet been prosecuted in Cambodia for hacking. But that could soon change with the Cybercrimes Draft Law, which, after the government began putting it together in 2012, may be taken up by the National Assembly today.
