T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a large number of embedded links, with one specifically pointing to a known malicious redirector at `ttraff.ru`. The heuristic `PDF_MALICIOUS_REDIRECTOR_LINK` confirms this, and `PDF_SEO_LINK_FARM` indicates a mass of external PDF links, suggesting a link farm for SEO manipulation or to host further malicious content. The document body itself is heavily obfuscated and contains a mix of text and what appears to be binary data, making its direct content analysis difficult, but the presence of numerous links is the primary indicator of malicious intent.
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.ru/pify?keyword=electrical+characterization+techniques+pdf
