T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file was flagged for containing a link to known malicious redirector infrastructure. This suggests the document's primary purpose is to lure the user to a potentially harmful website. No scripts were extracted, and the document body was heavily obfuscated, preventing further analysis of the specific lure. The presence of the malicious URL is the strongest indicator of malicious intent.

Heuristics 2

  • 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.
  • 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.
