MITRE ATT&CK

T1059.005 Visual Basic T1204.002 Malicious File T1105 Ingress Tool Transfer

The sample contains a VBA macro that executes upon opening the document. This macro constructs and writes a PowerShell command to a temporary file, which is then executed. The PowerShell command downloads a second-stage executable from a suspicious URL and saves it locally. The macro's intent is to download and execute a malicious payload, indicating a downloader or droppper functionality.

Heuristics 6

Document_Open macro high OLE_VBA_DOCOPEN

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.
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.

URL http://schemas.openxmlformats.org/drawingml/2006/main
Macro capabilities present but unconfirmed info MACRO_CAPABILITY_UNCORROBORATED

The document's VBA exposes execution capabilities (Shell/WScript/CreateObject/auto-exec) but nothing corroborates malicious intent — no obfuscation, memory-exec primitive, download+exec chain, encoded payload, LOLBin, DDE, AV hit, or suspicious URL. The verdict was capped at 'suspicious' so legitimate macro-heavy business documents are not flagged malicious on capability presence alone.
