T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a malicious redirector link, identified by the critical PDF_MALICIOUS_REDIRECTOR_LINK heuristic. The document body also contains a visual download button lure, reinforcing the malicious intent. The file is part of a link farm, with many embedded URLs pointing to Shopify domains, likely to improve search engine ranking for malicious content. The primary malicious URL is https://ttraff.com/pify?keyword=chuy%25E1%25BB%2583n+%25C4%2591%25E1%25BB%2595i+file+pdf+th%25C3%25A0nh+%25E1%25BA%25A3nh, which likely leads to further malicious content.
Heuristics 4
-
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.
-
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
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=chuy%25E1%25BB%2583n+%25C4%2591%25E1%25BB%2595i+file+pdf+th%25C3%25A0nh+%25E1%25BA%25A3nh
