- Uninstall affected or untrusted builds and reinstall only the vendor-signed fixed release from the official source if the tool is still required.
- Block unapproved DAEMON Tools installers and mirrors through application control and web filtering.
- Run EDR or antivirus scans on systems that installed or updated the product during the exposure window.
- Review startup items, services, drivers, scheduled tasks, and browser extensions for unwanted additions.
