Ha, I encountered this for the first time - the target is detected the Rurilib HTTP library on which the actual bullet is built by SSL fingerprint upon request and bans immediately. On v2, you can change the library to the system one, it works right away. But i prefer use Rurilib better.
So i think here is detection TSL fingerprint but not all. just RUrilib only. And ban this fingerprint. Its possible? and how i can recompilie rurilib with another Cipher Suites?
