MITRE ATT&CK

T1059.001 PowerShell T1566.001 Spearphishing Attachment

The file was detected as Emotet, a known downloader family. Static analysis revealed heuristics indicating the invocation of cmd.exe and PowerShell, consistent with Emotet's behavior. The document body contains a heavily obfuscated PowerShell command designed to decode and execute a second-stage payload, likely for further malware deployment.

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.
