TL;DR - The "Korean Leaks" campaign showcases a sophisticated supply chain attack against South Korea's financial sector.

TL;DR A Chinese APT group compromised a Philippine military company using a new, fileless malware framework called EggStreme. This multi-stage toolset achieves persistent, low-profile espionage by injecting malicious code directly into memory and leveraging DLL sideloading to execute payloads. The core component, EggStremeAgent, is a full-featured backdoor that enables extensive system reconnaissance, lateral movement, and data theft via an injected keylogger.
