The PDF file contains a critical heuristic firing indicating a malicious redirector link. The embedded URL, https://ttraff.club/wix?keyword=whirlpool+gold+accubake+system+gas+oven+manual, is the primary indicator of malicious intent. This suggests the document is designed to lure users to a potentially harmful website. No scripts were extracted from this sample.

Heuristics 2

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

  • Embedded URL info EMBEDDED_URL
    One 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.
