MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF contains numerous links, many pointing to disposable domains and employing UTM parameters, indicative of a link farm designed to obscure malicious destinations. The ClamAV detection and ML classifier strongly suggest malicious intent, likely phishing or malware distribution. The embedded URLs, such as 'https://infrive.ru/pbw?utm_term=watch+deadpool+online+123movies', are designed to trick users into clicking by promising access to popular content.

  • 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.
