MITRE ATT&CK

T1059.005 Visual Basic T1204.002 Malicious File

The file contains VBA macros, specifically a Document_Open macro, which is a common technique for executing malicious code upon opening a document. The ClamAV detection of 'Doc.Trojan.Thus-8' strongly suggests a known malware family. The document body presents a lure about a fashion launch party, likely to trick the user into enabling macros. No scripts were extracted, but the presence of the Document_Open macro indicates an attempt to execute code automatically.

Heuristics 5

ClamAV: Doc.Trojan.Thus-8 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Trojan.Thus-8
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAV

ClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
Document_Open macro high OLE_VBA_DOCOPEN

Document_Open macro
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.
