T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF file was identified as malicious due to its structure containing a large number of external links, a common technique for SEO poisoning or link farming. One of the embedded URLs, 'https://ttraff.cc/pify?keyword=bolet%25C3%25ADn+informativo+ministerio+de+seguridad+2019', is flagged as a malicious redirector. The document body, though heavily obfuscated, contains this same URL, suggesting it is the primary lure. The ML classifier also strongly indicated maliciousness.

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/pify?keyword=bolet%25C3%25ADn+informativo+ministerio+de+seguridad+2019
