T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF contains a mass of external links, many pointing to benign Shopify domains, but one critical link redirects to a known malicious infrastructure at 'ttraff.cc'. The document body, though heavily obfuscated, contains the text 'Tectonic plate boundaries worksheet answers' and the malicious URL, suggesting a lure to trick users into clicking the link. The presence of numerous PDF links and a malicious redirector indicates a likely attempt to lead the user to a phishing or malware download site.

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.
