MITRE ATT&CK
T1059.001 PowerShell

The PDF document contains an embedded URI pointing to a file hosted on blissfullmemories.net, which is presented as a driver download. The ML classifier strongly flagged this PDF as malicious. The presence of a visual download button, although low-signal on its own, supports the lure. The document body and heuristics indicate a social engineering attempt to trick the user into downloading potentially malicious content from external URLs.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9998

Heuristics 4

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • External URI info PDF_URI
    PDF contains an external URL action
  • Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTAL
    The same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
  • 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.
