MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with a critical heuristic indicating it's a trojan. A high-severity heuristic suggests the document is a lure, instructing the user to handle a password-protected archive, a common tactic to evade gateway scanning. The embedded script, though truncated, appears to be part of a downloader or obfuscation mechanism.

Heuristics 3

  • ClamAV: Doc.Trojan.AOOCAI-6751706-3 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Trojan.AOOCAI-6751706-3
  • Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LURE
    Document gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
  • 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.
