MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is detected as malicious by ClamAV with the signature Doc.Malware.00536d-6707118-0. Although VBA macros could not be extracted due to an unsupported format, the presence of an embedded URL suggests an attempt to engage the user with potentially malicious content. The document body contains obfuscated text, which is often used to hide malicious intent.

Heuristics 3

  • ClamAV: Doc.Malware.00536d-6707118-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Malware.00536d-6707118-0
  • Unsupported Office format for VBA extraction info OFFICE_FORMAT_UNSUPPORTED
    olevba could not extract VBA macros (AssertionError); format-agnostic byte-level scans still ran. Likely legacy, encrypted, or malformed OLE/OOXML — re-scanning the same bytes will yield the same outcome.
  • 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.
