Is Flixsign Web PKI safe?

Low risk

Flixsign Web PKI lets matching web pages send localStorage-derived signing commands to its local PKI native host.

The content script runs on app.flix-sign.com, localhost:3000, and matching amplifyapp.com subdomains, then attaches handlers to page elements with specific IDs. When triggered, it reads toSign or msg from page localStorage and forwards the action, thumbprint, fileHash, or text to the com.flixsign.windows.client.pki native host.

Where it sends data

Destinations our analysis observed Flixsign Web PKI contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
