T1566.001 Spearphishing Attachment
T1204.001 User Execution: Malicious Link
The PDF document contains numerous embedded URLs, many pointing to disposable hosting and redirectors, indicative of a phishing campaign. The 'SE_BRAND_CREDENTIAL_PHISH' heuristic specifically flags this as a brand-impersonation lure, likely attempting to steal user credentials. The presence of a link to 'resalured.ru' with a 'briggs+and+stratton+generator+carburetor+parts' UTM term suggests a targeted lure.

Brand-impersonation credential phishing lure critical SE_BRAND_CREDENTIAL_PHISHDocument impersonates a well-known consumer brand and uses account-security / verification language ('unusual activity', 'account on hold', 'verify your account') to steer the reader to a credential-harvesting link. Corroborated by: action link to abused redirector https://rozeravepirasaj.weebly.com/uploads/1/3/2/8/132816036/nexawikol_zobukuzetu_xogoxenazaju.pdf.

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://resalured.ru/strik?utm_term=briggs+and+stratton+generator+carburetor+parts PDF link annotation
