T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF document contains a large number of external links, a common tactic for SEO poisoning and phishing. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass of external PDF links, with the dominant host being 'kohlpaintinganddrywall.com'. The embedded document body text, though partially corrupted, contains a URL that matches one of the extracted links, suggesting a deliberate attempt to redirect users. No scripts were extracted from this sample.

Heuristics 4
-
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.
-
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 http://2psb9.slpny.com/uploads/1/3/0/5/130588261/130588261.html#nickel+affinity+chromatography+protein+purification PDF link annotation
