Is Lync safe?

Low risk

Lync fetches saved login fields from its servers and fills them into any web page from a right-click menu.

The extension loads on all http and https pages and retrieves your stored module credentials from app.letslync.com. Its right-click menu is available on every page and sends those values to the clicked page without checking that the page matches the saved site. The values are then written into matching form inputs or copied to the clipboard, so the page can read them.

Shared hosts - 1 hostname

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.

Where it sends data

Destinations our analysis observed Lync 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.

  • app.letslync.com

    Lync sends data to app.letslync.com. One other extension we have analyzed sends data here.
