T1566.002 Spearphishing Attachment
T1200 Hardware Add-Override
The PDF file contains a large number of embedded links, a technique often used to direct users to malicious websites for phishing or malware distribution. The heuristic PDF_MALICIOUS_REDIRECTOR_LINK specifically flags a link to traff.ru, indicating a known malicious redirector. The PDF_SEO_LINK_FARM heuristic further supports this by identifying a mass external PDF link farm, suggesting an attempt to manipulate search engine results or distribute content through numerous intermediary sites. No scripts were extracted from this sample.
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/pify?keyword=pulmonary+hypertension+pathophysiology+pdf
