Hackers associated with the Thailand branch of Anonymous took down several hundred Thailand justice and federal websites Tuesday after two Burmese migrant workers were sentenced to the death penalty last month for the murder of two British tourists in September 2014. The verdict has come under heavy criticism after claims that the police tortured the two men forcing them to confess to a crime they didn’t commit surfaced.

Anonymous, the loosely based hacktivist group spanning the globe claimed responsibility after all of Thailand’s federal and government websites began going offline, carrying out their second cyber-protest following their previous January 6 attacks. The 297 websites run by Thailand’s court of justice were found offline due to the murder of two backpackers that occurred on the Thai island of Koh Tao.

The Thailand case in which Anonymous has launched attacks against centers around the mysterious murder of British backpackers Hannah Witheridge, 23, and David Miller, 24, who were both found beaten to death on a beach at the Koh Tao island. It was reported that Witheridge was also raped before her death.

After a speedy 18-day trial in Thai courts, the two Burmese migrant workers, whose DNA was allegedly found on the victims, were convicted of murder. Following their conviction both men later said they were forced to confess after being tortured and not given proper interpreters to translate for them during the trial.

Anonymous is just one of the countless groups and individuals who have openly criticized the Thai justice system in this case.

“Anonymous is preparing a huge leak of all Thai officials involved in corruption in Thai Courts,” Anonymous Thailand announced on Facebook just before hundreds of Thai government websites went offline. “Anonymous has found the Thai courts to be GUILTY of unfair treatment of non Thai nationals, using scapegoats and using foreign prisoners as political pawns and for political gain. You have been found guilty by Anonymous and justice will prevail.”

Following their threat they began to publish pictures of the judges working the murder trial against Wai Phyo and Zaw Lin, pronouncing the judges guilty and labeling them corrupt.

Anonymous hacktivists also announced “We stand by Laura,” referring to Laura Witheridge’s elder sister who openly criticized the Thailand government on Facebook stating the police and justice system are corrupt.

“The thai police chief had no intentions of giving us an update,” wrote Laura Witheridge in a statement posted to her Facebook page Sunday, describing when her family went to retrieve her sister’s body from Thailand. “After all, the bungled investigation meant he had nothing to tell us. The invitation was merely an opportunity for the press to take photographs of our family.”

The latest operation of demanding justice for the two men who are believed to be wrongly accused of murder is just one of the dozens of operations Anonymous has carried out over the past few months. Recent Anonymous operations included unmasking KKK members and declaring a vicious cyber-war against ISIS.

Anonymous is supporting a campaign that asks tourists to boycott Thailand entirely until changes are made with the way Thai police handle investigations involving foreign tourists.

It’s been over 20 hours since the initial attacks started and many of the Thai websites are still offline at the time of publication.
