That’s what I thought too as soon as I saw the title of this thread. My telco uses a heavily obfuscated script where all the variables are just a bunch of hex that uses every conceivable fingerprint technique in the book. Shockwave Flash, remote fonts, WebRTC, Silverlight, vector graphics, HTML5 cookies, hardware fingerprinting etc.
