MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF is identified as a phishing lure due to its small size and image-only content, typical of a screenshot designed to hide a clickable link. The embedded URL `https://baarspo.ru/strik?utm_term=search+google+for+image+missing` and numerous other links to disposable domains suggest a phishing campaign. ClamAV detection as `Pdf.Phishing.Trojan` further supports this assessment.

Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LURE

PDF has 1 image(s), only 0 text block(s), carries a click-outward action, and is only 49 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_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.
