An anonymous reader writes: "A new User Access Control (UAC) bypass technique relies on altering Windows registry app paths and using the Backup and Restore utility to load malicious code without any security warning," reports BleepingComputer. The technique works when an attacker launches the Backup and Restore utility, which loads its control panel settings page. Because the utility doesn't known where this settings page is located, it queries the Windows Registry. The problem is that low-privileged users can modify Windows Registry values and point to malware. Because the Backup and Restore utility is a trusted application, UAC prompts are suppressed. This technique only works in Windows 10 (not earlier OS versions) and was tested with Windows 10 build 15031. A proof-of-concept script is available on GitHub. The same researcher had previously found two other UAC bypass techniques, one that abuses the Windows Event Viewer, and one that relies on the Windows 10 Disk Cleanup utility
