MITRE ATT&CK
T1059.005 Visual Basic
T1566.001 Spearphishing Attachment
The sample contains VBA macros, including a Document_Open macro and a UserForm hidden-property command stager, which are indicative of malicious intent. The VBA code appears to be obfuscated but the presence of CreateObject and auto-execution mechanisms suggests it's designed to download and execute a secondary payload. The ClamAV detection further supports the malicious classification.
Heuristics 7
-
ClamAV: Doc.Malware.Sagent-9238710-0 critical CLAMAV_DETECTIONClamAV detected this file as malware: Doc.Malware.Sagent-9238710-0
-
VBA macros detected medium 4 related findings OLE_VBA_MACROSDocument contains VBA macro code
-
VBA UserForm hidden-property command stager critical OLE_VBA_USERFORM_HIDDEN_COMMAND_STAGERVBA 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_DOCOPENDocument_Open macro
-
CreateObject call high OLE_VBA_CREATEOBJCreateObject call
-
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXECCompiled 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_URLOne 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 In document text (OLE body)
