T1059.001 PowerShell
T1204.002 Malicious Link
The PDF file contains a large number of external links, many of which point to similarly structured URLs on different domains, indicating a link farm or SEO spam operation. The document body, though heavily obfuscated, contains text related to 'Educacion primaria en mexico' and references wkhtmltopdf, suggesting a lure to educational content. The heuristic PDF_SEO_LINK_FARM strongly suggests this is a malicious link farm designed to drive traffic or potentially host malicious content. 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.
-
Clickable PDF combines external action with parser-evasion structure high PDF_ACTION_PARSER_EVASIONPDF has an external clickable URI together with object graph or xref structures that make parsers disagree, such as divergent duplicate objects, parser divergence, or xref offset mismatch. That combination is stronger than a plain link: the document is both an outward-action carrier and a parser-confusion/evasion sample.
-
External URI info PDF_URIPDF contains an external URL action
-
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://sdrvowners.org/uploads/1/3/0/8/130873861/130873861.html#educacion+primaria+en+mexico
