title: GoToAssist Temporary File Drop in Windows Temp Directory
id: 86ac261b-d322-4b94-93a5-89ac9ca32ea3
status: test
description: This rule identifies the creation of a specific GoToAssist temporary artifact by matching file paths under the Windows user Temp directory associated with “GoToAssist Remote Support Expert.” Attackers may use legitimate remote support software to establish interactive access, and transient installation or support artifacts can appear in user-local temporary locations during setup. It relies on Windows file event telemetry that records the target filename/path so the directory substring can be matched.
