SINGAPORE - All 13 school websites which were hacked into on Wednesday have been fixed, even as the authorities hunt for the culprits.

"As at 6pm, all the affected sites have been restored," said a Ministry of Education (MOE) spokesman yesterday, adding that a police report has been lodged. "No privileged information was compromised."

Checks by The Straits Times revealed that at least several of the affected websites, including those belonging to Woodlands Ring Primary and Greendale Primary, were hosted by information technology provider ACP.

When contacted, the firm's founder Alan Poh said his company is working with MOE and the police after what he termed an "injection" attack, which involves exploiting a software vulnerability.

Little is known about the individual or group operating as "Jack Riderr", the moniker used to sign off on the defaced school websites. Online checks show that it is linked to online groups going by names such as "Black Ops", "Hacker-Hacker Malaysia Bersatu", "Johor Hacking Crew" and "Malaysia Black Hat Community".

"Black hat" refers to hackers who violate computer security for malicious reasons or personal gain.

While logos of a smiling white mask and a man without a head - both associated with the Anonymous hacktivist group - also surfaced during online checks into Jack Riderr, the latest attacks do not appear to be connected to the intrusions into the Istana and Prime Minister's Office websites earlier this month. Five men are being investigated for these incidents.

On Wednesday, the Singapore Art Museum released a statement saying that e-mail addresses and phone numbers of 4,000 individuals who had participated in the museum's activities in 2011 and this year had been uploaded onto a server in New Zealand.
