Zero Breach Toolkit
A free, open-source spyware check: scan computers and phone backups offline for mercenary spyware traces.
Visit tool →Details
Originally named Zero-Breach-Toolkit, it is a free, open-source check for traces of mercenary spyware (Apache-2.0 licence, ~4,200 stars on GitHub): version 2 is a double-click desktop app for Windows, macOS and Linux, in 27 languages. It scans computers, Android phones and iPhone backups for traces of known mercenary spyware such as Pegasus, Predator, Graphite and Candiru. Scans are read-only — they do not modify source evidence or system settings — and make no network requests and upload nothing; every report states the strength of each finding and what could not be checked. Listing note: a clean result is never proof of safety; if you believe you are being targeted right now, get expert help first — you do not need to run it before asking.
Who it's for
Journalists, activists and others at higher risk of targeted surveillance, and anyone who wants an offline health check for their devices.

“Listing notes: read-only scanning, no network, no uploads — those three are why it earns trust; reports say plainly what they cannot check, a negative result is not proof of safety, and if you think you are being targeted, talk to an expert first rather than relying on this alone.”
