T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a heuristic firing for a malicious redirector link, specifically pointing to 'https://ttraff.ru/wb?keyword=unified%20soil%20classification%20system%20flow%20chart%20pdf'. This indicates an attempt to lure users to a malicious site under the guise of providing a technical document. The document body, though heavily obfuscated, also contains this URL and a list of other Shopify-hosted PDF links, suggesting a link farm or SEO poisoning tactic to increase visibility of the malicious redirector. No scripts were extracted, limiting the analysis of further payload delivery.
Heuristics 3
-
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.
-
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/wb?keyword=unified%20soil%20classification%20system%20flow%20chart%20pdf
