Is Netcraft Extension safe?
Netcraft Extension sends visited URLs and matching form-risk reports to Netcraft endpoints.
Netcraft Extension checks page and frame URLs against Netcraft's reputation service as you browse. Its credential-protection feature can read card-like form values on pages, compare them with outgoing requests, and report matching incidents with the page URL and reason to Netcraft.

What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 5 hostnames
Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

What it can do

Where it sends data
Destinations our analysis observed Netcraft Extension 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.
