T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file was flagged as malicious due to the presence of a link to a known malicious redirector. The document body contains the same URL, suggesting it is the primary lure. The heuristic PDF_MALICIOUS_REDIRECTOR_LINK and the embedded URL confirm this malicious intent. The file also contains a large number of embedded links, as indicated by the PDF_SEO_LINK_FARM heuristic, which are likely part of a link farm to improve search engine ranking for malicious content.

Heuristics 3
-
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF 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_FARMSmall 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_URLOne 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/wix?keyword=imagine+dragons+smoke+and+mirrors+do
