T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF was flagged for containing a large number of embedded links, a technique often used to obscure malicious destinations or to create link farms for SEO poisoning. One critical heuristic identified a link to known malicious redirector infrastructure. The document body, though heavily corrupted, appears to contain metadata related to 'Manualidades navideñas 2018 paso a paso', suggesting a lure to trick users into clicking the malicious links.

Heuristics 3
-
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
-
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.
-
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 https://ttraff.cc/wb?keyword=manualidades%20navide%C3%B1as%202018%20paso%20a%20paso
