T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The sample is a PDF document flagged as malicious by ClamAV and an ML classifier. It contains a high number of external links, many of which are likely part of a link farm designed to improve SEO for malicious content. The heuristic 'SE_ADVANCE_FEE_SCAM_LURE' strongly suggests the document's content is intended to deceive users into believing they are receiving a prize or parcel, a common advance-fee fraud scheme. While no scripts were explicitly extracted, the PDF structure and the presence of external links indicate a potential for malicious redirection or payload delivery.

Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
-
Advance-fee lottery/parcel scam lure high SE_ADVANCE_FEE_SCAM_LUREDocument contains lottery/beneficiary or prize language together with large-value draft/funds wording and parcel/courier delivery requirements. This is a classic advance-fee fraud document shape.
-
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://golowaki.ru/123?utm_term=jio+mobile+video+calling+software PDF link annotation
