T1566.001 Spearphishing Attachment
T1539 Steal Application Data
The PDF document was flagged by ML classifiers and ClamAV as malicious, specifically as a phishing or credential harvesting lure. The heuristic 'SE_MFA_LURE' indicates the document's content is designed to trick users into providing multi-factor authentication details. While no scripts were explicitly extracted, the presence of numerous external URLs, many hosted on potentially disposable domains, suggests a phishing campaign aiming to redirect users to malicious sites.

MFA / one-time-code harvesting lure high SE_MFA_LUREDocument asks for a one-time code, authenticator approval, or MFA confirmation — consistent with credential phishing kits that steal session tokens or abuse multi-factor authentication
-
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://prana.video/wp-content/plugins/super-forms/uploads/php/files/q885vm0l0nfik39k1eqb05j4qn/69615893556.pdf In PDF document text
