T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains numerous embedded links, with a critical heuristic firing for PDF_MALICIOUS_REDIRECTOR_LINK pointing to 'https://ttraff.ru/wix?keyword=biomedical+statistics+and+informatics+journal'. Another critical heuristic, PDF_SEO_LINK_FARM, indicates a large number of external links, with 'https://cdn.shopify.com/s/files/1/0435/4742/6975/files/oxford_phonics_world_readers_level_1.pdf' being the first identified. The document body, though heavily obfuscated, also contains these URLs, suggesting a tactic to drive traffic to malicious or SEO-manipulated content.
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.
