MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF is identified as an image-only lure, typical for phishing campaigns. It contains a single external URI pointing to 'https://traffnew.ru/aws?keyword=black+ops+4+voyage+of+despair+guide', which is likely the malicious destination. The ML classifier strongly indicates maliciousness, supporting the phishing or malware distribution intent.

Heuristics 3

  • Small PDF is a non-clustered link farm on disposable hosting medium PDF_SEO_DISPOSABLE_LINK_FARM
    Small 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.
