MITRE ATT&CK

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

The sample contains a VBA macro that is automatically executed upon opening the document, as indicated by the Document_Open and OLE_VBA_PCODE_AUTOEXEC_EXEC heuristics. The macro utilizes CreateObject, a common technique for executing arbitrary code. The ClamAV detection of 'Doc.Malware.Sagent-9780539-0' strongly suggests malicious intent, likely involving the download and execution of a secondary payload.

Heuristics 7

ClamAV: Doc.Malware.Sagent-9780539-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Malware.Sagent-9780539-0
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.
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.
