T1204.002 Malicious Link
The PDF document was flagged as malicious due to a critical heuristic indicating it contains links to known malicious redirector infrastructure. Additionally, it exhibits characteristics of a PDF SEO link farm, embedding numerous external links, many of which point to Shopify-hosted PDFs. The primary malicious URL identified is https://ttraff.ru/pify?keyword=%25CE%25B2%25CE%25B9%25CE%25B2%25CE%25BB%25CE%25AF%25CE%25BF+%25CE%25B3%25CE%25BB%25CF%258E%25CF%2583%25CF%2583%25CE%25B1%25CF%2582+%25CE%25B2+%25CE%25B4%25CE%25B7%25CE%25BC%25CE%25BF%25CF%2584%25CE%25B9%25CE%25BA%25CE%25BF%25CF%258D+%25CE%25B3+%25CF%2584%25CE%25B5%25CF%258D%25CF%2587%25CE%25BF%25CF%2582+pdf, suggesting a redirection chain designed to lead users to harmful content.
Machine Learning
- Nyx PDF Classifier malicious score 1.0000
Heuristics 5
-
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.
-
Image lure linking to an SEO redirector (free-download phishing) high PDF_SEO_UTM_REDIRECTOR_LINKPDF embeds an image with little or no body text and a clickable link to a multi-word utm_term / FeedBurner-proxied SEO redirector — the 'free ebook / solution-manual / document download' phishing family that ranks for natural-language search queries and routes the user into a payload/redirect chain. The PDF carries no exploit; the risk is the linked destination. Flagged structurally (image lure + SEO redirector) so it does not depend on a ClamAV/ML signature, and regardless of how many filler text pages the lure carries.
-
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=%25CE%25B2%25CE%25B9%25CE%25B2%25CE%25BB%25CE%25AF%25CE%25BF+%25CE%25B3%25CE%25BB%25CF%258E%25CF%2583%25CF%2583%25CE%25B1%25CF%2582+%25CE%25B2+%25CE%25B4%25CE%25B7%25CE%25BC%25CE%25BF%25CF%2584%25CE%25B9%25CE%25BA%25CE%25BF%25CF%258D+%25CE%25B3+%25CF%2584%25CE%25B5%25CF%258D%25CF%2587%25CE%25BF%25CF%2582+pdf In PDF document text
