title: Windows Inveigh HackTool Execution Artefacts via Inveigh File Indicators

status: test
description: This rule identifies Windows hosts where Inveigh execution-related files are present by matching specific dropped artefact filenames. Adversaries may use Inveigh to perform credential-related network activities, and the creation of recognizable log and tool files can indicate deployment. Telemetry relies on Windows file event logs that capture filenames matching Inveigh-*.txt and Inveigh tool binaries/scripts (.dll, .exe, .ps1).
