Is UchiHelper safe?

Medium risk

UchiHelper sends Uchi.ru access tokens and uid cookies to dz-helper.ru while automating exercises.

When you use UchiHelper on Uchi.ru exercise pages, it reads an access token from the page and sends it with a DZ-Helper account key to dz-helper.ru to fetch exercise event data. It also reads the Uchi.ru uid cookie and sends it with the DZ-Helper key to dz-helper.ru for account checks.

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 UchiHelper 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.
