APAC is now a proving ground for some of the world’s most sophisticated cyber actors. From state-backed groups to commercial contractors and organized cybercrime, adversaries in the region move quickly, reuse infrastructure, and mix espionage with financially motivated operations. For CISOs, the challenge is no longer a lack of alerts — it’s the lack of context.

This white paper explains why an adversary-centric intelligence approach is essential for APAC defenders. Instead of collecting more indicators, it focuses on understanding who the attackers are, how they operate, and what drives their campaigns. Drawing on TeamT5’s decades of regional research, it breaks down real cases including the i-Soon contractor leak and the Mackay Memorial Hospital ransomware attack, to show how attacker ecosystems really function.
