Local website and forum Kallang Roar, touted as the "voice of Singapore football", was hacked on Wednesday morning.
Users attempting to access the site at www.kallangroar.com arrive at the above page, which announces "Your Website is got owned by Myanmar Muslim Cyber Force (sic)" (MMCF).
While their exact motives remain unclear, the MMCF claim to be part of international activist network Anonymous, with hacks targeted at "racist people". A sign-off at the bottom of the page reads, "We Never Lose We Never Worng (sic)".
The entire message is framed below an image of Guy Fawkes, a rebel icon popularised by anti-fascist, pro-anarchy film V for Vendetta.
MMCF runs a Facebook page listing sites hacked by the group -- some of which purportedly includes the "USA President" forum and the online community of Australian football club Melbourne Victory.
Meanwhile, Kallang Roar, which launched in 2005, acknowledged the hack on its Facebook and Twitter accounts, and promised to "get the site online again after office hours".
The Singapore Under-23 football team plays Myanmar this evening in Malaysia's Merdeka Tournament.
While the young Lions' campaign is over after losing to Malaysia and Thailand, Myanmar still has a shot at making the final -- provided they beat Singapore tonight.
