The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) is trying to get its website back online after it was defaced Wednesday afternoon.
According to Pagasa's Twitter account, the website is under maintenance. It also referred users to an alternate website, kidlat.dost.gov.ph, which was however also offline.
According to reports, the defacement replaced the meteorological agency's front page with a white back ground and the words "Hacked by Net user ! Just fun a fun !!" The page also mentioned "Team: X-f*ck!" and an e-mail address: firstname.lastname@example.org
QQ is a Chinese instant-messaging service with "over 700 million Chinese QQ accounts."
The Pagasa website is currently offline.
On April 25, suspected Chinese hackers also defaced the website of the Department of Budget and Management.
Earlier that week, the Presidential Communications Development and Strategic Planning Office reported attempted denial-of-service attacks on its websites. Before that, the University of the Philippines website was also hacked.
Hackers from the Philippines have also reportedly defaced Chinese government websites in retaliation.
The cyber-attacks are believed related to tensions between the Philippines and China over a standoff at the Panatag shoal. The standoff, which began in early April when Chinese ships blocked a Philippine Navy ship from arresting suspected Chinese poachers, has yet to be resolved.
