T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF contains a high-risk heuristic firing for a random URL link, pointing to a suspicious PDF hosted on 'privateguardingserviceagainstdanger.site'. Another embedded URI leads to 'resalured.ru'. ClamAV detection as 'Pdf.Phishing.Trojan' further supports a malicious classification. The presence of these indicators suggests the document is designed to redirect users to malicious content, likely for phishing or malware delivery.

  • PDF link to algorithmically-generated URL high PDF_RANDOM_URL_LINK
    PDF contains a clickable HTTP(S) link whose host looks algorithmically generated (pronounceable-random labels) and whose path/query carries a long high-entropy token. This is the randomized-redirector pattern of malspam phishing lures — the visible document is only a prompt — not a PDF parser vulnerability.
  • 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.
