MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell T1204.002 Malicious Link

The PDF document uses a FIFA World Cup theme to entice users. It contains a critical heuristic firing for a malicious redirector link pointing to 'https://ttraff.cc/wb?keyword=fifa%20world%20cup%202018%20fixtures%20pdf%20in%20bangla'. Additionally, it exhibits characteristics of a link farm, with numerous embedded URLs, many hosted on cdn.shopify.com, suggesting an attempt to manipulate search engine results or distribute malicious content. No scripts were extracted, but the presence of a malicious redirector is a strong indicator of a phishing or malware distribution 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.
