MITRE ATT&CK

T1059.005 Visual Basic

The file contains VBA macros, specifically a Document_Open macro, which is a common technique for executing malicious code upon opening the document. The document body presents a fake assignment to mask the malicious intent. While the specific payload is not clear from static analysis, the presence of macros and the embedded URL suggest a downloader or phishing attempt.

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.
