T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a lure for a free textbook download, which is a common social engineering tactic. It embeds multiple links, with one specifically pointing to a known malicious redirector at 'ttraff.ru'. The ML classifier also strongly indicates maliciousness. The primary attack vector appears to be directing users to malicious content via a deceptive link.

- Nyx PDF Classifier malicious score 1.0000
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=free%20download%20nelson%20textbook%20of%20pediatrics%2020th%20edition%20pdf
