T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains numerous links, a technique often used in SEO link farms to artificially boost search engine rankings or to redirect users to malicious sites. One prominent link points to a known malicious redirector at 'ttraff.ru', disguised as a search result for 'advanced mathematical concepts answer key pdf'. The document body, though heavily obfuscated, appears to contain metadata related to this lure. No scripts were extracted from this sample.
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=advanced%20mathematical%20concepts%20answer%20key%20pdf
