T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The sample is a PDF file identified as malicious by multiple heuristics, including ClamAV and an ML classifier. It contains numerous external links, with a significant number pointing to potentially malicious or SEO-spam-related domains, such as `sunuf.co.za` and `herve-coiffure.ci`. The PDF structure and the presence of many external links suggest a phishing or malware distribution attempt, masquerading as a document download.

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.

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/YmrXLWy8?keyword=woods%20dixie%20cutter%20m5%20manual%20instructions%20manual%20download
