“Even if you did not have one of the extensions, you may not be immune to the data leak,” said Jadali.
“If you or someone with whom you communicated with online had one of the invasive extensions installed on your computer, you may have been impacted by the DataSpii leak.”
Google and Mozilla have disabled the browser extensions in Chrome and Forefox, claiming they breach their policies, so they are no longer available for download.
However, if you already have one installed on your browser, it may continue to harvest your data.
In order to stop the data collection, Jadali recommends uninstalling the extensions immediately – disabling them may not be enough.
As a precaution, if you have downloaded one of the identified extensions, you should also consider changing your passwords.
