MITRE ATT&CK
T1059.001 PowerShell T1059.003 Windows Command Shell

The file is an Excel spreadsheet that contains heuristics indicating PowerShell execution and visible command execution instructions. The embedded URL, although marked as benign, is likely the source for a second-stage payload. The document body is heavily obfuscated and unreadable, preventing further analysis of its specific lure.

Heuristics 3

  • Reference to PowerShell high SC_STR_POWERSHELL
    Reference to PowerShell
  • Visible LOLBin command execution instruction high SE_LOLBIN_RUN_COMMAND
    Document contains instructions or visible command text involving Windows script/execution tools such as PowerShell, mshta, cmd, rundll32, or regsvr32
  • 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.
