Authorities respond to hacking of Prime Minister's site

The  Infocomm Development Authority has said it is currently investigating the hacking of the Prime Minister’s Office (PMO) website yesterday.The PMO main website is still working, and the government is working to restore the page that has been compromised, it said.The official IDA statement also said:“A sub page for search on the PMO website was reported to be compromised on 7 November 2013 at 11.17pm.  A vulnerability in that subpage was exploited to display pages from other sources. This vulnerability is known as cross-site scripting. “The hacking came shortly after Singapore Prime Minister Lee Hsien Loong made the vow that the government would "spare no effort" in going after Anonymous members who threatened to wage a cyber war against Singapore.In an announcement to the local media, he said:"Our IT network, the Internet, our communications have become an essential part of our business and our lives now. And, therefore, when somebody threatens to do harm to it we take that very seriously and we will spare no effort to try and track down the culprits and if we can find him, we will bring him to justice and he will be dealt with severely."Late last night, a section of www.pmo.gov.sg which was hacked read: "It's great to be Singaporean today" next to a Guy Fawkes mask by an anonymous group. Another image next to it read: "PM Lee warns hackers: We will track you down - even if you think you're 'anonymous'".The section was taken offline shortly after a picture of the hacking incident was seen on a Facebook posting.The threat on cyber hacking first emerged last week when a video warning by an anonymous group threatened to bring down key infrastructures in Singapore in an attempt to show of protest against the state’s new licensing rules imposed on websites. Shortly after, the SPH site was also hacked.(Read also: FB, Microsoft, Google battle hackers and Hacking: The new world marketing threat  )
