T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
This PDF document employs social engineering tactics by masquerading as exam questions and answers to trick users into downloading further malicious content. The heuristic 'SE_SECRET_RECOVERY_LURE' indicates a critical attempt to solicit sensitive information such as private keys or passwords, which is a common phishing technique. The presence of multiple links to compromised WordPress upload directories suggests a distribution infrastructure designed to host and serve malicious files.

-
Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LUREDocument gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
-
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.
-
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://amiablediamonds.com/wp-content/plugins/super-forms/uploads/php/files/459d645de6dbf9366a4dc731122cd242/similekavoluxadime.pdf
