The sample is a PowerPoint file that contains an embedded PE executable. This executable is likely the primary payload. The document body text is in Japanese and appears to be corporate motivational content, which is likely a lure to disguise the malicious nature of the file. No scripts were extracted from this sample.

Heuristics 3

  • Embedded PE executable critical OLE_EMBEDDED_EXE
    MZ/PE header found inside document — possible embedded executable
  • Suspicious extracted artifact info 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.
  • 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.
