Is DataSpark Tools safe?

Low risk

DataSpark Tools places its DataSpark API key in a Walmart page iframe URL.

On Walmart product pages, the extension builds a dataspark.co login URL with its DataSpark API key in the query string and inserts it as an iframe in the page DOM. Scripts running on the same page can read that iframe src and recover the API key.

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 DataSpark Tools 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.

  • dataspark.co

    DataSpark Tools sends data to dataspark.co. No other extension we have analysed sends data here.
