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

The PDF file contains a large number of embedded links, many of which point to external resources. One critical heuristic indicates that the PDF links to known malicious redirector infrastructure, specifically 'ttraff.ru'. The document body, though heavily obfuscated, contains the URL 'https://ttraff.ru/pify?keyword=guide+michelin+paris+2018', suggesting a lure to a malicious site disguised as information about the 'Guide Michelin Paris 2018'. The presence of numerous links, many hosted on Shopify, indicates a link farm designed to distribute traffic to malicious destinations.

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.
    URL https://ttraff.ru/pify?keyword=guide+michelin+paris+2018
