The file is detected as Xls.Dropper.Agent-7132800-0 by ClamAV. Heuristics indicate the use of Windows Script Host and bitsadmin for downloading, along with a command execution attempt via 'cmd /c'. The embedded URL likely serves as the download source for a secondary payload, suggesting a dropper functionality.

    Reference to Windows Script Host
  • Reference to bitsadmin (download) high SC_STR_BITSADMIN

  • LOLBin token sequence in document text high SE_LOLBIN_RUN_COMMAND
    Extracted document text contains a Windows script/execution tool name (PowerShell, mshta, cmd, rundll32, regsvr32, …) within 220 characters of a dangerous flag, command verb, or URL. This is a visible 'run this' instruction in HTML/PDF/RTF lure bodies, or — in macro-laden Office files — the macro's own string-pool entries appearing adjacent in extracted text.
  • 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.
