The file is an Office document containing VBA macros, specifically an AutoOpen macro, which is a common technique for executing malicious code upon opening. The presence of CreateObject calls and the ClamAV detection as 'Doc.Dropper.Generic' strongly suggest this document is a dropper. The macro likely downloads and executes a second-stage payload, although the specific URL or payload is not directly extractable from the provided evidence. The document body was truncated and did not provide further context on the lure.

Heuristics 6

  • ClamAV: Doc.Dropper.Generic-9823794-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Dropper.Generic-9823794-0
  • AutoOpen macro high OLE_VBA_AUTOOPEN
    AutoOpen macro
  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject call
  • 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 project inside OOXML medium OOXML_VBA
    Document contains vbaProject.bin — VBA macros present
  • 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.
