MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 User Execution: Malicious Link
The PDF is identified as an image-only lure, a common tactic for phishing or malware delivery. It contains a critical malicious redirector link to 'ttraff.ru' and a large number of external PDF links, many hosted on Shopify, suggesting a link farm for SEO manipulation or traffic redirection. The ML classifier also strongly indicated maliciousness. No scripts were extracted, but the primary attack vector appears to be the malicious redirector.

Heuristics 5
-
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.
-
Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LUREPDF has 2 image(s), only 0 text block(s), carries a click-outward action, and is only 16 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
-
Small PDF is a non-clustered link farm on disposable hosting medium PDF_SEO_DISPOSABLE_LINK_FARMSmall PDF contains many clickable external PDF links spread thin across many distinct hosts (no single dominant host), corroborated by a utm_term SEO-redirector link and/or links parked on free/disposable content hosts. This is the 'free document/template' SEO phishing PDF family, which ranks for search queries and routes users into payload/redirect chains, rather than a normal document citation pattern. The PDF itself carries no exploit — the risk is the linked destinations.
-
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=advances%20in%20social%20network%20mining%20and%20analysis%20pdf In PDF document text
