Operation Flash Cobra
2020-05-05 • Strangereal Intel •
Operation Flash Cobra is analyzed as Lazarus activity that begins with a malicious document using remote template injection to retrieve and execute the next-stage DOTM macro. The macro decodes embedded content, extracts an architecture-specific DLL and lure document, and stores the DLL under a OneNote-looking path in the user’s AppData Local Microsoft directory. Execution is tied to the document auto-open flow, which calls exported DLL functionality with victim-specific identifiers and displays the lure document while the malicious component runs. The excerpt further notes persistence-related identifiers, rundll32-style DLL execution, thread creation, and sqlite3.dll functionality apparently used to parse SQLite databases and extract information.
