T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF file contains numerous embedded links, with a critical heuristic firing indicating a malicious redirector. The primary URL, 'https://ttraff.com/wb?keyword=application%20letter%20example%20pdf', is identified as a malicious redirector. Another heuristic indicates a PDF link farm, with 'https://cdn.shopify.com/s/files/1/0432/6083/8050/files/gigatuvatan.pdf' being one of the linked PDFs. The document body, though heavily obfuscated, appears to contain metadata related to application letters and PDF generation, suggesting a lure.
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/wb?keyword=application%20letter%20example%20pdf
