MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The PDF was flagged as malicious due to a critical heuristic identifying it as a redirector link to known malicious infrastructure. Additionally, it contains a large number of external PDF links, many hosted on Shopify, suggesting a link farm intended for SEO manipulation or malicious redirection. The embedded URL points to 'ttraff.ru', a known malicious redirector. While no scripts were extracted, the PDF structure and embedded links strongly indicate a malicious intent to lure users to harmful sites.

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.ru/pify?keyword=tomorrow+will+be+better+book
