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

This PDF file contains a link to a known malicious redirector, ttraff.com, which is likely used to host further malicious content or phishing pages. The document body, though heavily obfuscated, contains text related to 'Dragon Age Origins' and the URL itself, suggesting a lure to entice users to click the malicious link. The PDF also hosts a large number of links to other PDFs hosted on Shopify, likely as part of a link farm to improve SEO for the malicious redirector.

Heuristics 4

  • 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.
  • Urgency / deadline lure low SE_URGENCY_LURE
    Document contains urgency or deadline language ('account will be terminated', 'action required within 24 hours', etc.) — useful context, but low-signal without other findings
  • 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.
