T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
This PDF file is identified as malicious due to its structure, which includes a high number of embedded links designed to create a link farm. The primary malicious link, 'https://ttraff.ru/pify?keyword=antibiogram+test+pdf', acts as a redirector, likely leading to further malicious content. The document body contains garbled text but includes the malicious URL and several other PDF links, some of which are hosted on benign platforms like Shopify, potentially to lend legitimacy. The ML classifier strongly supports the malicious verdict.

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.
-
