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

This PDF document contains a significant number of embedded links, many pointing to Shopify domains, which is characteristic of a link farm designed to manipulate search engine results or distribute malicious content. The primary malicious link, https://ttraff.ru/pify?keyword=chatuchak+market+section+guide, is identified as a redirector to known malicious infrastructure. The document body, though partially corrupted, contains text related to 'Chatuchak market section guide' and the malicious URL, suggesting a lure to trick users into clicking the link.

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.
