T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF document contains a large number of external links, a technique often used for SEO poisoning or to redirect users to malicious sites. The document body text, though partially corrupted, suggests a lure related to PDF merging tools. The presence of numerous links to various domains, all following a similar pattern of numeric slugs and PDF file extensions, indicates a coordinated effort to distribute malicious content. No scripts were extracted, but the primary attack vector appears to be social engineering via link farms.

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://wenji.bpmtc.com/uploads/1/3/0/5/130539756/130539756.html#offline+tool+to+merge+pdf+files PDF link annotation
