SN 1008: HOTP and TOTP - SyncThing, Auto-Updates, Sci-Fi Recs

---Meta winds down 3rd-party content filtering. Is encryption soon to follow? ---Taking over abandoned Command & Control server domains (strictly for research purposes only). ---IoT devices to get the "Cyber Trust Mark" — Will anyone notice or care? ---"SyncThing" receives a (blessedly infrequent) update. ---Government email is not using encryption? Really? ---Email relaying prevents point-to-point end-to-end encryption and authentication. ---Just because Let's Encrypt doesn't support email doesn't mean it's impossible. ---What Sci-Fi does ChatGPT think I (Steve) should start reading next? ---To auto-update or not to auto-update? — is that one question or two? ---And, until today, we've never taken a deep dive into the technology of time-varying 6-digit one time tokens.

SN 1004: A Chat with GPT - China's Telecom Hack, Microsoft Activation Cracked, Coding with ChatGPT 4...

This week, Steve and Leo discuss the recent 'Salt Typhoon' hack of U.S. telecom providers by China, TPM 2.0 requirement for Windows 11, Microsoft's newly hacked Windows activation system, Apple patenting AI facial and body recognition, and much more. Steve also shares an intriguing conversation he had with the ChatGPT 4o AI system while working on an update to GRC's DNS Benchmark tool. ---All telecom providers have been hacked and may still not be safe to use. So now the government is recommending that we use our own encrypted communications. ---The plan to obsolete all non-TPM 2.0 PCs remains well underway. Microsoft must be feeling the heat, so they're taking time to not apologize. ---Whoops. Microsoft's product activation system has been fully hacked. All Windows and Office products may now be easily activated without any licensing. ---Here come the AI patents. Apple patents AI recognizing people by what they're wearing after earlier seeing their faces and noting what they're wearing. ---Zoom wasn't encrypting their early video conferencing. They're still trying to get out from under the mess their lies created for them. ---AWS introduces physical data terminal locations where users can go to perform massive data transfers to and from the cloud. ---The FTC has set its sights on data brokers.
