T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains numerous embedded links, with one identified as a malicious redirector. The document body, though partially corrupted, contains text related to a 'Jcb backhoe loader parts manual pdf' and includes the malicious URL, suggesting a lure for phishing or malware delivery. The presence of a link farm heuristic further indicates an attempt to obscure the malicious destination.

Heuristics 3

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • 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.
