Zero Breach Toolkit is an open-source tool that compares Windows, macOS and Linux records, Android devices and iPhone backups with public indicators for known spyware such as Pegasus. It describes scans as read-only, making no intentional network requests or uploads and writing only necessary temporary copies and reports. Separate indicator updates and Android acquisition can use the network or change device state. Its privacy documentation states that this is not operating-system network isolation and that other software may upload reports saved in cloud-synced folders. Findings must therefore be interpreted alongside coverage and unexamined evidence, rather than as a definitive infection verdict.
