01Summary

Between August 20 and November 5, 2013, Anonymous carried out a series of cyberattacks targeting Singaporean government and political websites. The operation began with attacks on the Ang Mo Kio Town Council website and escalated to target the National Museum of Singapore (from which they leaked 3,600 emails, IP addresses, and names), the PAP Community Foundation, and The Straits Times newspaper. The attacks were motivated by opposition to Singapore's restrictive media environment and internet censorship policies, including the government's blocking of certain websites. The sustained campaign was one of the longest-running Anonymous operations in Southeast Asia.

02Background

Singapore has strict media regulations and internet censorship policies. The government maintains tight control over online content through licensing requirements and website blocking. Anonymous viewed these policies as an attack on free expression.

03Technical analysis

The attacks utilized a combination of DDoS, website defacement, and data exfiltration. The National Museum breach involved SQL injection to access the database and extract user data.
