T1059.007 JavaScript
T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
This PDF file contains embedded JavaScript, which is a common technique for exploiting PDF vulnerabilities to execute malicious code. The numerous external URLs, many hosted on compromised CMS upload directories, suggest a phishing or credential harvesting campaign. The ML classifier and ClamAV detection strongly indicate malicious intent, likely involving the exploitation of a client vulnerability to redirect the user to one of the listed phishing sites.

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.
