SINGAPORE - Singapore Prime Minister Lee Hsien Loong's official website was hacked Thursday by apparent members of activist group Anonymous after he vowed to hunt down anyone who attacks the city-state's technological network.
"It's great to be Singaporean today," read a mocking headline in a section of www.pmo.gov.sg next to the group's trademark Guy Fawkes mask, a symbol of anti-establishment defiance worldwide.
Next to it was another image saying: "PM Lee warns hackers: We will track you down - even if you think you're 'anonymous'".
The defaced section was quickly taken offline after the hacking incident surfaced in a posting on Facebook. The rest of the site was working normally.
In a statement issued early Friday, the government's Infocomm Development Authority said it was investigating the incident.
"The PMO (Prime Minister's Office) main website is still working, and we are working to restore the page that has been compromised," it said.
Social media and independent websites have become the main arenas of political debate in Singapore, whose mainstream newspapers and broadcasters are widely perceived to be pro-government.
The hacking took place a day after Lee told local journalists that his government would "spare no effort" in going after Anonymous members who last week threatened to wage a cyber war against Singapore.
