This detection rule monitors changes to the Windows registry setting for Internet Explorer's `DisableFirstRunCustomize` value. By tracking modifications to this registry key, the rule helps identify unauthorized alterations that could prevent the browser's first run wizard from executing. The first run wizard is an important security measure; it guides users through initial configurations and settings. If the setting is altered (specifically set to either 1 or 2 as DWORD values), it may indicate user evasion tactics or malicious intent to suppress security prompts. The rule filters events based on the processes accessing this registry key, specifically `explorer.exe` and `ie4uinit.exe`, to minimize false positives arising from legitimate administrative actions. Should there be attempts to change this setting outside of the standard execution context, an alert will be generated. This is especially relevant in environments utilizing group policy, where such settings might be controlled centrally, and may lead to unintended alerts. Detecting changes in this context can help organizations ensure adherence to their security policies and mitigate potential threats.
