Malware-Infected Systems in Singapore More Than Double in 2025

In 2025, Singapore experienced a significant increase in malware-infected systems, rising to 284,300 from 117,300 in 2024. This surge is attributed to persistent malicious activity and enhanced detection of botnet devices. The rise in infections is linked to the growing use of malware-as-a-service (MaaS) and the proliferation of consumer IoT devices with weak security. The Cyber Security Agency of Singapore (CSA) noted that the misuse of AI technologies has also contributed to the speed and scale of cyberattacks. Despite this, phishing incidents decreased by 20% to 4,800 cases in 2025. The CSA is implementing stricter security requirements for residential routers by the end of 2027 to combat these threats. The report highlights the evolving threat landscape, including the use of AI in cyberattacks and scams. The outgoing CSA chief emphasized the need for improved defenses against these emerging threats.

Key Points: • Malware-infected systems in Singapore rose to 284,300 in 2025, more than double from 2024. • The increase is driven by malware-as-a-service operations and insecure IoT devices. • Phishing incidents fell by 20%, indicating a potential shift in attack vectors.
