A purported member of the Internet hacking group Anonymous has breached a blog linked to Singapore's leading newspaper, heightening concerns about cybersecurity among the city-state's government agencies.

The Straits Times said it removed a page on a website that features blog posts by the newspaper's writers after it was taken over and defaced by the hacker Friday.

The hacker claimed a Straits Times journalist published a "very misleading" blog post about a threat purportedly issued by Anonymous against Singapore's government this week to protest contentious new online licensing regulations.

The Straits Times said on its main website that it has lodged a police report and that government agencies have been on alert since the initial threat surfaced in a YouTube video Thursday.
