T1566.002 Spearphishing Attachment
T1204.002 User Execution: Malicious File
The PDF contains a mass of external links, many pointing to Shopify domains, but one specific URL, 'https://ttraff.ru/pify?keyword=icao+annex+17+pdf+free+download', is flagged as a malicious redirector. This suggests the document is designed to trick users into clicking the link under the guise of a free PDF download, leading them to malicious infrastructure. No scripts were extracted, and the document body is largely unreadable binary data, but the presence of the malicious redirector and the link farm heuristic strongly indicate 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=icao+annex+17+pdf+free+download
