Anonymous members that were arrested in Singapore and charged with defacing websites, and spray-painting graffiti identifying the international hackivist group could face, along with jail time, between three and eight strokes of the cane. One of the websites that was defaced by the hackers is linked to Prime Minister Lee Hsien Loong.

The attacks coincide with a pledge from the government to crackdown on the group. The Diplomat reports that among the members arrested is James Raj, a 35-year-old who allegedly posted a Guy Fawkes mask, symbol of the group, on the Ang Mo Kio district website late last month. Websites belonging to the prime minister’s office were also hacked following threats of a crackdown by the authorities and Lee.

Raj, who uses “The Messiah” as his call sign, apparently carried out the attack from neighboring Malaysia. He faces up to three years in jail and a fine of $8,000.

Another five men have been charged with vandalism after spraying painting Anonymous slogans and face a fine of up to $2,000, three years in jail and could receive between three and eight strokes of the cane.

Anonymous had been stepping up its attacks in Asia as part of the November 5 Million Mask March designed to coincide with Guy Fawkes Day. It was staged in more than 400 cities around the world to protest a range of causes including corruption, bad government, corporate greed and the environment.
