MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell T1204.002 Malicious Link

The PDF contains multiple invisible links that repeatedly point to the URL http://particlecommit.site/Fungicide-Application-Timing-On-Soybeans/pdf/elisautobody.com. This heuristic indicates a lure to download a payload, likely disguised as a document related to fungicide application timing. The presence of numerous embedded URLs suggests a broad phishing or malware distribution attempt.

Heuristics 2

  • Invisible/repeated PDF links deliver payload file critical PDF_REPEATED_PAYLOAD_LINK_LURE
    PDF uses invisible link annotations and points to a direct payload download. Repeated invisible links or lure-like payload names such as document/unlock/verify archives match malware-delivery PDF carriers where the page is only a prompt and the real payload is fetched from the linked URL.
  • 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.
