Unfortunately I don't have much reading material to provide. It's a bit of an arms war, so the latest and greatest countermeasures are typically kept secret/protected by NDA. The rabbit hole can go very deep and can differ from company to company. The most drastic example I can think of was an unverified rumor that a certain company would "fake" log users in when presented with valid credentials from a client they considered suspicious. They would then monitor what the client did - from the client's point of view it successfully logged in and would begin normal operation. If server observed the device was acting "correctly" with the fake login token, they would fully log it in. If the client deviated from expected behavior, it would present false data to the client & ban the client based on a bunch of fancy fingerprinting. Every once in awhile, someone will publish their methods/software; Salesforce and their SSL fingerprinting software comes to mind: https://github.com/salesforce/ja3 https://github.com/salesforce/ja3
