T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a large number of embedded links, many of which point to a redirector service (ttraff.cc). The document body, though heavily obfuscated, contains text that appears to be a lure related to 'exercicios 8 ano doc'. The heuristic PDF_MALICIOUS_REDIRECTOR_LINK confirms that at least one URL leads to malicious infrastructure. The PDF_SEO_LINK_FARM heuristic indicates a large number of external links, likely to obscure the malicious redirector. The ML classifier also strongly flagged this PDF as malicious.

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/wix?keyword=angulo+central+e+inscrito+exercicios+8+ano+doc
