Patchwork APT, also known as Dropping Elephant, Monsoon, and Hangover Group, has been active since at least 2015. This threat actor primarily focuses on gathering political and military intelligence, targeting organizations across South and Southeast Asia. Patchwork is recognized for its persistence and adaptability, often reusing and modifying existing tools rather than developing its own exploits. Despite this, the group has achieved significant success by leveraging effective social engineering tactics, customized lures, and multi-layered obfuscation techniques in their operations.
