Is Tally Tab safe?

Medium risk

Tally Tab sends searches typed on its new-tab page to r.bsc.sien.com with affiliate tracking parameters.

Tally Tab replaces the browser's new tab page with a calculator and search form. When a user submits that search form, it reads the typed query and redirects the tab to r.bsc.sien.com/search with FORM, PC, PTAG, and q parameters.

What this publisher told the store about itself, and the other listings that told it the same thing.

OZ

Same store account

2 other listings published from this account, 8k+ users between them. 1 of them carries a finding.

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 Tally Tab 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.
