MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment T1140 Deobfuscate or Obfuscate Malicious Code

The sample contains a VBA macro that is automatically executed upon opening the document, as indicated by the 'Document_Open' macro and 'OLE_VBA_PCODE_AUTOEXEC_EXEC' heuristic. The macro appears to be obfuscated and attempts to create an object, likely to download and execute a second-stage payload. The ClamAV detection name 'Doc.Malware.Emodldr-10033991-0' further supports its malicious nature.

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.
