T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file contains numerous external links, many of which are part of an SEO link farm, suggesting a phishing or malicious redirection scheme. The document body, though heavily obfuscated, contains text related to a 'November 2019 calendar malaysia template', which serves as a lure. The presence of PDF_SEO_LINK_FARM and PDF_SEO_UTM_REDIRECTOR_LINK heuristics, along with the ML_NYX_PDF_MALICIOUS and ClamAV detections, strongly indicates malicious intent. The primary malicious URL identified is https://resalured.ru/123.

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.
-
Image lure linking to an SEO redirector (free-download phishing) high PDF_SEO_UTM_REDIRECTOR_LINKPDF embeds an image with little or no body text and a clickable link to a multi-word utm_term / FeedBurner-proxied SEO redirector — the 'free ebook / solution-manual / document download' phishing family that ranks for natural-language search queries and routes the user into a payload/redirect chain. The PDF carries no exploit; the risk is the linked destination. Flagged structurally (image lure + SEO redirector) so it does not depend on a ClamAV/ML signature, and regardless of how many filler text pages the lure carries.

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/123?utm_term=november+2019+calendar+malaysia+template PDF link annotation
