Compromised Web Developer Extension Steals Cloudflare Tokens

Upon receiving news that the popular Chrome Extension, Web Developer, had been compromised, I became curious about exactly how malicious the highjacking was. Most sites are reporting that it injects ads. It's more nefarious than that. Since the extension calls out to an attacker-controlled URL, the payload hosted at that URL could be changed to anything at any time.

At the time of inspection, the code checks to see if the victim is on the Cloudflare domain. If it is, it starts an XHR request to fetch the users' API token and ships it, along with the victim's email, to a remote server.
