MITRE ATT&CK

T1566.001 Spearphishing Attachment

This PDF is identified as malicious by ClamAV and an ML classifier, exhibiting characteristics of a phishing lure. It contains a full-page image designed to obscure clickable links, a common tactic to deceive users into visiting malicious sites. The document body is heavily obfuscated, but the presence of numerous external URIs, including one pointing to 'xajibur.ru', suggests an attempt to redirect the user to potentially harmful content.

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 48 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.
