Singapore Prime Minister Lee Hsien Loong’s official website has been hacked by people claiming to be members of the hacking group Anonymous.
The attack comes a day after Lee said he would track down the group.
He made the comments after a person claiming to be part of the group posted an online video in which he threatened to hack government websites.
Singapore’s internet and phone regulator said part of the website had been “compromised” late on Thursday.
“The PMO main website is still working, and we are working to restore the page that has been compromised,” the Infocomm Development Authority said in a statement.
The hackers had posted an image of a Guy Fawkes mask – the symbol of the Anonymous group – on the PM’s website with the words: “It’s great to be Singaporean today.”
