Is PhishWall safe?

Clean risk

PhishWall reports every tab URL to a local desktop agent and injects a persistent identifier into requests to Japanese banking sites.

On each tab load, switch, or close, the extension sends the current page URL and tab details to a PhishWall agent running at 127.0.0.1:8888. At startup it retrieves a persistent GUID from the same local agent and injects it—along with version and client identifiers—as custom headers on all outbound requests to a list of over 40 Japanese banking domains.

Where it sends data

Destinations our analysis observed PhishWall 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.
