T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file was identified as malicious due to a critical heuristic firing for PDF_MALICIOUS_REDIRECTOR_LINK, indicating it points to known malicious redirector infrastructure. Additionally, the PDF_SEO_LINK_FARM heuristic fired, revealing a large number of embedded external links, with the primary malicious URL being https://ttraff.ru/pify?keyword=canadian+solar+hiku+pdf. The document body contains garbled text but also includes several URLs, reinforcing the link farm finding. The presence of these numerous links suggests a phishing or malware distribution attempt.
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=canadian+solar+hiku+pdf
