T1566.001 Spearphishing Attachment
T1204.002 User Execution: Malicious File
This PDF file was detected as malicious by ClamAV, specifically as a phishing trojan. Static analysis revealed it functions as a link farm, directing users to numerous external websites, many hosted on compromised CMS platforms or disposable domains. The embedded URLs, such as 'https://infrive.ru/uplcv?utm_term=babetta+228+manual', are likely used to distribute further malicious content or conduct phishing campaigns. The presence of multiple compromised upload links and disposable hosting indicates a deliberate effort to obscure the true destination and evade detection.

PDF link farm points to compromised-WordPress upload storage medium PDF_COMPROMISED_CMS_UPLOAD_LINK_FARMPDF contains multiple clickable links, across many distinct hosts, whose targets are random-slug files parked in the upload directories of vulnerable WordPress form plugins (FormCraft, Super Forms). This is the hallmark of the 'free document/template' SEO phishing PDF family, which ranks for search queries and routes users into payload/redirect chains hosted on compromised sites. The PDF itself carries no exploit — the risk is the linked destinations.

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