MITRE ATT&CK

T1059.005 Visual Basic T1059.001 PowerShell T1204.002 Malicious File

The file is a malicious DOCX document containing a VBA macro. The macro is configured to auto-execute upon opening, indicated by the 'Document_Open' and 'OLE_VBA_PCODE_AUTOEXEC_EXEC' heuristics. This macro likely downloads and executes a second-stage payload, as suggested by the 'OLE_VBA_CREATEOBJ' firing and the ClamAV detection name 'Doc.Downloader'. The presence of obfuscated content in the DOC BODY further supports this. The SHA256 hash is included as a primary IOC.

Document_Open macro
CreateObject call high OLE_VBA_CREATEOBJ

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.
Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
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.
