T1204.002 Malicious File
T1566.002 Spearphishing Attachment
The PDF file contains a large number of external links, many of which point to PDF files hosted on various domains. One of these links, http://michaelshusko.com/uploads/1/3/0/5/130551739/130551739.html#ivms+4200+for+mac+download, is presented as a download for 'Ivms 4200 for mac'. This suggests a social engineering lure to trick the user into downloading a malicious file. The heuristic PDF_SEO_LINK_FARM indicates a pattern of generating numerous links, likely for SEO manipulation or to host multiple malicious payloads.

Heuristics 5
-
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.
-
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
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://michaelshusko.com/uploads/1/3/0/5/130551739/130551739.html#ivms+4200+for+mac+download PDF link annotation
