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

The PDF contains a link that redirects to malicious infrastructure, disguised as a bingo card template. The heuristic PDF_MALICIOUS_REDIRECTOR_LINK confirms the malicious nature of the redirector URL. Additionally, the PDF_SEO_LINK_FARM heuristic indicates a large number of embedded links, many of which point to potentially compromised or malicious domains. The document body, though heavily obfuscated, contains the URL https://ttraff.com/pify?keyword=bingo+card+template+pdf, reinforcing the lure.

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.
