MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The ML classifier strongly indicates maliciousness in this PDF. The document body, though heavily obfuscated, contains a URL that is also flagged by heuristics. This URL, http://attorneyspacesharing.com/uploads/1/3/0/7/130740255/130740255.html#mapa+conceptual+de+teoria+marxista, is likely intended to host a malicious payload or redirect the user to a phishing site. No scripts were extracted from this sample.

Heuristics 3

  • 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.
