The spread of malware through Chrome extensions seems to be an increasingly widespread problem as well as cryptocurrency mining through any web page. Recent articles report similar issues such as wired.it (on October 10th 2017) and Maxime Kjaer (on July 18th 2016).
The goal of the creators was to offer a simple service to get shortened urls, while underneath allowing them to earn monero.
After two weeks of my reporting, the extension has been removed from the Chrome Web Store, and we can only imagine how much money the creators earned.
Wow, everyone is willing to be rich lol.
