T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains embedded links that point to a known malicious redirector infrastructure, specifically `https://ttraff.cc/pify?keyword=asme+section+ix+interpretations+pdf`. The document body, though heavily obfuscated, appears to contain keywords related to 'Asme section ix interpretations pdf' and the authoring application 'wkhtmltopdf', suggesting a lure to download a malicious PDF. The heuristic `PDF_MALICIOUS_REDIRECTOR_LINK` strongly indicates malicious intent.

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.
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
-
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.cc/pify?keyword=asme+section+ix+interpretations+pdf
