T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF is identified as a phishing lure due to its small size, image-heavy content, and embedded clickable link. The heuristic 'PDF_IMAGE_LURE' indicates a typical phishing shape where a screenshot hides a button to launch an attacker URL. Although no scripts were explicitly extracted, the presence of numerous embedded URLs, many of which are hosted on potentially disposable domains, suggests a link farm designed to redirect users to malicious content. The ClamAV detection further supports its malicious nature.

Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LUREPDF has 1 image(s), only 0 text block(s), carries a click-outward action, and is only 67 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_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 http://www.myhhsi.com/wp-content/plugins/super-forms/uploads/php/files/663607de8e4d46138b759ca6045e79a7/36241344483.pdf In PDF document text
