T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains numerous embedded links, with a critical heuristic identifying a link to a known malicious redirector infrastructure at https://ttraff.me/wix?keyword=capitalism+game+android+code. Another heuristic indicates a PDF link farm, with the primary link pointing to a Shopify domain. The document body, though heavily obfuscated, contains text related to 'capitalism game android code' and the malicious URL, suggesting a lure to a potentially malicious site. No scripts were extracted, but the presence of multiple links and the redirector heuristic strongly indicate a phishing or redirection attempt.

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.
