Summary
Targeted activity affecting the Philippines and Myanmar have been identified and attributed to a group that's being tracked as LuminousMoth by researchers with Kaspersky. Further research has revealed a loose resemblance to HoneyMyte (aka Mustang Panda) due to an overlap in infrastructure use as well as common TTPs. The initial attack vector was spear-phishing attacks that link targets to a malicious archive file disguised as a Microsoft Word document with government information. Once infected, the malware uses DLL-sideloading and can spread to peripherals such as USB devices, perform network discovery, steal passwords, and communicate with the adversaries C2 server.
Our Threat Research team gathers and analyzes information from multiple open and closed sources before disseminating intelligence reports. This campaign was researched by Kaspersky and shared publicly.
