Malaysia's biggest cyber threats in 2026

Malaysia’s digital economy is expanding rapidly, and so are the threats. Recent reports show ransomware incidents have risen sharply and now hit small and medium enterprises disproportionately, while attackers increasingly use AI to automate and personalise attacks. As a result, these trends affect organisations across Peninsular Malaysia and East Malaysia, including Sarawak, so local businesses and citizens should prioritise basic cyber hygiene now. To begin with, attackers use large language models and voice or video cloning to craft highly convincing scams and impersonations. This is called AI-powered phishing and social engineering. Moreover, deepfakes and AI-generated messages make verification harder. Therefore, always verify unusual requests through a second channel and train staff to spot subtle signs of fraud. Another growing concern is that ransomware attacks on Malaysian organisations have increased significantly. SMEs now account for a large share of victims, and the average breach cost has risen. To mitigate this risk, practical steps can be taken, including maintaining offline backups, applying timely patches, and testing incident response plans.
