Ok so that is exactly not the conversation I want to have nor in this format.

So please forget me for the next 3 weeks (SG17 in Korea) and I will try to understand how best to frame what should be framed.

Since this IAB report is mainly looking into encrypted data, I would assume that you are interested in the cases where Ransomware attack is leveraging encrypted data such as Encrypted Client Header (ECH) which can be used to hide the adversaries command and control [https://www.ietf.org/archive/id/draft-campling-ech-deployment-considerations-07.txt<https://www.google.com/url?q=https://urldefense.com/v3/__https:/www.ietf.org/archive/id/draft-campling-ech-deployment-considerations-07.txt__;!!GjvTz_vk!TCEUzvgyrwR484kRDlnSTqYySSCORBNX0MW3d1BSPYbggzqy7zcY7DxxTYSjjJNxvrHZTmc9bFTRV4V6$&source=gmail-imap&ust=1693664482000000&usg=AOvVaw2e-mo-OVLMRrZUXEKYp6F3>]

It would be senseless to use ECH for C&C, since they are not hosting multiple services.  From what I have seen, most C&C centers are taken down by looking at the IP address and working from there, not examining TLS handshakes.
