MITRE ATT&CK

T1059.005 Visual Basic T1204.002 Malicious File

The file is a Microsoft Word document containing VBA macros, specifically a Document_Open macro that is designed to execute upon opening. The document body explicitly instructs the user to 'Enable editing' and 'Enable content', a typical social engineering tactic to bypass macro security. The presence of a 'macros.bas' file and the ClamAV detection as 'Doc.Downloader.Generic-7611954-0' strongly suggest this document is a downloader for further malicious payloads. No specific family could be identified.

Heuristics 8

ClamAV: Doc.Downloader.Generic-7611954-0 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Downloader.Generic-7611954-0
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
Suspicious extracted artifact info 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.
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.
