MITRE ATT&CK

The PDF document contains a large number of embedded links, identified by the PDF_SEO_LINK_FARM heuristic, which are likely intended to redirect users to malicious websites. The document body text, though partially corrupted, suggests a lure related to a '2006 freightliner columbia service manual', aiming to trick users into clicking the malicious links. No scripts were extracted from this sample.

Heuristics 3

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
