MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains a large number of external links, many pointing to domains with numeric or generic slugs, indicative of a link farm or SEO spam tactic. The heuristic 'PDF_SEO_LINK_FARM' specifically flags this behavior, with 'fucktard.xyz' being a dominant host among the linked domains. The document body, though heavily obfuscated, contains a URL that mirrors one of the extracted links, suggesting a deliberate attempt to redirect users. The primary attack pattern appears to be social engineering through deceptive links within the PDF.

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://my-iei.com/uploads/1/3/0/7/130739117/130739117.html#fundamentals+of+data+structure+by+ellis+horowitz+pdf PDF link annotation
