Google chrome store has removed two adblockers that were found to be stealing user data.
Nano Defender and Nano Adblocker have been found guilty of stealing user data and have since been removed from the chrome store.
The extensions did not contain the data collection code when they were published more than a year ago. But, during October 2020 that code block was added. Turns out, the original developer of the extensions had sold the two extensions to a developer team from Turkey.
According to this article, the extension was modified to collect user’s IP address, country, URLs, time of user’s web requests, HTTP methods used (get, post, etc), size of HTTP responses, HTTP status response code, information about user’s operating system and the device the OS is running on, time spent in each web page and URLs navigated.
