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

The PDF file contains a heuristic firing indicating a malicious redirector link. The document body, though heavily obfuscated, contains text that appears to be a lure for 'Chiltons online manuals'. The primary malicious IOC is the URL https://ttraff.cc/wix?keyword=chiltons+online+manuals, which is linked directly from the document and flagged as malicious. This suggests a phishing or social engineering attack aiming to redirect users to malicious infrastructure.

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.
