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

The PDF contains a critical heuristic firing indicating it links to known malicious redirector infrastructure. The primary URL, https://gettraff.ru/mozel?keyword=parts+of+centrifugal+pump+and+their+function+pdf, suggests a lure related to technical documentation, likely intended to trick users into clicking through to a malicious site. Numerous other embedded URLs were also extracted, further supporting the malicious intent.

Heuristics 2

  • 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.
  • 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.
