MITRE ATT&CK

T1059.005 Visual Basic T1204.002 Malicious File

The sample contains a VBA macro that is automatically executed upon opening the document. This macro attempts to read from several hardcoded file paths, suggesting it is designed to load and execute a second-stage payload. The ClamAV detection name 'Doc.Downloader' further supports this analysis.

CreateObject call
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC

Compiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
VBA macros detected medium OLE_VBA_MACROS

Document contains VBA macro code
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
