Workarounds and solutions

| Type of Risk | Description | |--------------|-------------| | Privilege Escalation | If the application is malicious, it can install rootkits, steal SAM hashes, or disable security software. | | Ransomware | With admin rights, ransomware can encrypt shadow copies, map network drives, and disable recovery options. | | Persistent Backdoors | Admin access allows installation of scheduled tasks or services that survive reboots. | | Accidental System Damage | Even non-malicious but buggy software can delete critical system files or corrupt registry hives when running at high integrity levels. | getuidx64 require administrator privileges

Indicators of Compromise (IoCs)

  1. Service Creation: getuidx64 often creates a temporary service to load the kernel driver. Monitor for sc create commands pointing to unsigned or suspicious binaries.
  2. Test Signing Mode: Many custom drivers require "Test Signing" to be enabled via bcdedit /set testsigning on. This is a massive red flag in a production environment.
  3. DSE Bypass: If the tool uses a vulnerable legitimate driver (BYOVD - Bring Your Own Vulnerable Driver) to load, look for the loading of known vulnerable drivers (e.g., RTCore64.sys, AsIO.sys).

Antivirus Alerts: Many security programs will flag this file as a "Potentially Unwanted Program" (PUP) or a threat.
