MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.001 Malicious Link

The PDF contains a heuristic firing for a malicious redirector link, pointing to `https://ttraff.com/pify?keyword=canon+60d+shutter+count+software+free`. The document body, though heavily obfuscated, contains references to 'Canon 60d shutter count software free', suggesting a lure to trick users into clicking the malicious link. No scripts were extracted, and the PDF structure itself did not reveal further malicious intent beyond the embedded link.

Heuristics 2

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    PDF 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.
  • 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.
    URL https://ttraff.com/pify?keyword=canon+60d+shutter+count+software+free
