The PDF contains a heuristic firing for SE_SECRET_RECOVERY_LURE, indicating it prompts the user for sensitive recovery information. Additionally, a PDF_EVAL heuristic suggests the presence of executable JavaScript within the document, likely used to facilitate the recovery secret phishing attempt. No specific malware family could be identified.

Heuristics 3

  • Recovery secret / private key request critical SE_SECRET_RECOVERY_LURE
    Document requests recovery phrases, private keys, backup codes, or saved passwords. Requests for these secrets in a document are high-risk.
  • eval() call high PDF_EVAL
    eval() found — commonly used for obfuscated exploit execution
  • 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.
