T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a large number of embedded URLs, many of which point to compromised WordPress sites using the 'super-forms' plugin. The heuristic 'PDF_SEO_DISPOSABLE_LINK_FARM' indicates a link farm on disposable hosting, and the 'ML_NYX_PDF_MALICIOUS' and 'CLAMAV_DETECTION' firings confirm its malicious nature. These elements suggest the document's primary purpose is to act as a lure, redirecting users to potentially malicious or phishing websites.

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.
-
External URI info PDF_URIPDF contains an external URL action
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://www.prowallpanama.com/wp-content/plugins/super-forms/uploads/php/files/bc99b46a3afc483a89b79a5f2021d288/betekidekomorevatewu.pdf In PDF document text
