MITRE ATT&CK

T1059.005 Visual Basic T1204.002 Malicious File

The document presents a lure to enable macros, disguised as a court filing form. Upon enabling macros, the 'Document_Open' macro is executed, which utilizes a GetObject call. This is consistent with a downloader pattern, likely intended to fetch and execute a second-stage payload. The ClamAV detection 'Doc.Downloader.Sagent-7643873-0' further supports this assessment.

Heuristics 8

ClamAV: Doc.Downloader.Sagent-7643873-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Downloader.Sagent-7643873-0
Document_Open macro high OLE_VBA_DOCOPEN

Document_Open macro
GetObject call high OLE_VBA_GETOBJ

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.
VBA macros detected medium OLE_VBA_MACROS

Document contains VBA macro code
Macro/content-enable lure medium SE_ENABLE_LURE

Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
