MITRE ATT&CK

T1059.005 Visual Basic

The file is a Microsoft Word document containing a Document_Open VBA macro, identified by ClamAV as Doc.Trojan.Story-1. The macro source code is obfuscated, but its presence and the critical ClamAV detection strongly indicate malicious intent. The macro is likely responsible for executing a secondary payload, as suggested by the 'VBA Chr string obfuscation' heuristic.

Heuristics 6

ClamAV: Doc.Trojan.Story-1 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Trojan.Story-1
Document_Open macro high OLE_VBA_DOCOPEN

Document_Open macro
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
Urgency / deadline lure low SE_URGENCY_LURE

Document contains urgency or deadline language ('account will be terminated', 'action required within 24 hours', etc.) — useful context, but low-signal without other findings
