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

This PDF file was flagged as malicious by ML classifiers and ClamAV. It contains multiple embedded URLs, including one pointing to 'jottigo.ru' which is associated with a lure about reading welder blueprints, and another to 'you-bestshop.xyz' which is identified as a link farm on disposable hosting. The presence of these links suggests an attempt to redirect users to malicious content, likely for phishing or malware distribution.

  • 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.
