MITRE ATT&CK
T1059.001 PowerShell T1566.001 Spearphishing Attachment

The file was detected as Emotet, a known banking trojan and downloader. It contains obfuscated PowerShell commands that, when decoded, appear to download and execute a second-stage payload. The presence of the PowerShell command and the ClamAV detection strongly indicate malicious intent.

Heuristics 4

  • ClamAV: Doc.Dropper.Emotet-6769504-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Dropper.Emotet-6769504-0
  • Reference to PowerShell high SC_STR_POWERSHELL
    Reference to PowerShell
  • LOLBin token sequence in document text high SE_LOLBIN_RUN_COMMAND
    Extracted document text contains a Windows script/execution tool name (PowerShell, mshta, cmd, rundll32, regsvr32, …) within 220 characters of a dangerous flag, command verb, or URL. This is a visible 'run this' instruction in HTML/PDF/RTF lure bodies, or — in macro-laden Office files — the macro's own string-pool entries appearing adjacent in extracted text.
  • 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.
