T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF file contains multiple embedded links, with one pointing to a known malicious redirector. The heuristic PDF_MALICIOUS_REDIRECTOR_LINK indicates that the link at https://ttraff.com/pify?keyword=fourier+transform+of+delta+function is part of malicious infrastructure. Additionally, the PDF_SEO_LINK_FARM heuristic suggests a mass external PDF link farm, with the first URL being https://cdn.shopify.com/s/files/1/0434/4433/8838/files/zabunijiwozalopinan.pdf. These findings suggest a social engineering attack aimed at redirecting users to potentially harmful content.
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.com/pify?keyword=fourier+transform+of+delta+function
