In two other separate incidents, the police received reports on Nov 8 on the alleged "hacking" of websites belonging to the Prime Minister's Office (PMO) and Istana.
Police investigations revealed that the suspect(s) had exploited a vulnerability in the said websites to display pages from other sources.
Police has since established the identities of five suspects, Singaporean men aged between 17 and 45. The five suspects are currently assisting the police in their investigation.
Current indications are that these two cases are unrelated to each other and to the first two cases of hacking and vandalism.
