Is ClickLearn Connector safe?

Medium risk

ClickLearn Connector fetches arbitrary JavaScript from its remote server and executes it on every open browser tab.

On startup, the extension retrieves a JavaScript payload from services.clicklearn.dk and broadcasts it to all open tabs via chrome.tabs.sendMessage. A content script running in the MAIN world on every page receives this payload and executes it using an obfuscated eval() call. Separately, the extension monkey-patches XMLHttpRequest on all pages to capture IFS Aurena and IFS FSM API response bodies, and its postMessage relay accepts instructions from any web origin without validating the sender.

Strong link to a flagged operator: 1 of the 3 other listings from the same operator is rated high or critical for malicious behavior. Flagged: ClickLearn Assist (high).

Where it sends data

Destinations our analysis observed ClickLearn Connector 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.

  • services.clicklearn.dk

    ClickLearn Connector sends data to services.clicklearn.dk. No other extension we have analyzed sends data here.
