MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with multiple critical heuristic firings indicating the presence of VBA macros and a Document_Open macro. The macros are likely responsible for executing malicious code, potentially downloading and running additional payloads. The embedded URL, while benign, is noted as present within the document text.

Heuristics 5

ClamAV: Doc.Trojan.Marker-40 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Trojan.Marker-40
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.

URL http://www.apple.com/DTDs/PropertyList-1.0.dtd
