T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a malicious redirector link disguised as a helpful guide for merging PDFs. The heuristic PDF_MALICIOUS_REDIRECTOR_LINK confirms the link points to known malicious infrastructure. The PDF_SEO_LINK_FARM heuristic indicates a large number of outbound links, many of which are likely part of a link farm to improve search engine ranking for malicious content. The document body and embedded URLs reinforce the lure of a PDF-related topic.
Heuristics 4
-
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.
-
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
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.com/wb?keyword=how%20to%20merge%20pdfs%20using%20foxit%20reader
