T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
The PDF was flagged by ClamAV as a phishing trojan and ML classifiers indicated maliciousness. It contains a high-risk heuristic for an image lure linking to an SEO redirector, specifically 'https://sunuf.co.za/XSRYdR1H?utm_term=android+webview+adjustpan+not+working'. This redirector likely serves as a gateway to a phishing page or a malware download, aligning with the 'Spearphishing Attachment' and 'Exploitation for Client Execution' techniques. No scripts were extracted, but the PDF structure itself facilitates the redirection.

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://sunuf.co.za/XSRYdR1H?utm_term=android+webview+adjustpan+not+working PDF link annotation
