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

This PDF document contains a large number of embedded links, many of which point to a link farm hosted on Shopify. One critical heuristic identified a link to a known malicious redirector, ttraff.ru, which is likely used to obscure the final malicious destination. The document body contains garbled text but also includes the URL that triggered the critical heuristic, suggesting a lure to click on the provided link. No scripts were extracted, but the presence of a malicious redirector and a link farm indicates a phishing or redirection attack.

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.
