T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
T1059.007 JavaScript
The sample is a PDF document flagged by multiple heuristics as malicious, including brand-impersonation credential phishing (Amazon) and ML-based detection. It contains numerous embedded URLs, with a prominent one leading to a redirector that ultimately points to a PDF file, suggesting a multi-stage attack. The presence of PDF-specific heuristics and the nature of the embedded URLs indicate an attempt to exploit users through social engineering, likely for credential theft or further payload delivery.

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://wirorovikematu.weebly.com/uploads/1/3/1/0/131071137/wetinuke-wanapu-sarin.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://jacksth.ru/wix?keyword=unmatched+air+traffic+control+cheat+apk PDF link annotation
