T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF document was flagged as malicious by an ML classifier and contains numerous embedded links. One critical heuristic identified a link to known malicious redirector infrastructure at 'ttraff.ru'. Another heuristic noted a large PDF link farm, with many links pointing to Shopify domains, suggesting a potential SEO poisoning or content farm strategy. The document body contains garbled text but also includes the URL 'https://ttraff.ru/pify?keyword=comment+afficher+les+formules+sur+excel+2010', reinforcing the malicious redirector finding. No scripts were extracted from this sample.

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=comment+afficher+les+formules+sur+excel+2010
