SN 1014: FREEDOM Administration Login - Apple's UK Privacy Showdown, $1.5 Billion Crypto Heist

Apple disables Advanced Data Protection for new UK users. Paying ransoms is not as cut and dried as we might imagine. Elon Musk's "X" social media blocks "Signal.me" links. Spain's soccer league blocks Cloudflare and causes a mess. Two new (and rare) vulnerabilities discovered in OpenSSH. The U.S. seems unable to evict Chinese attackers from its Telecom systems.

SN 1011: Jailbreaking AI - Deepseek, "ROUTERS" Act, Zyxel Vulnerability
2
Why was DeepSeek banned by Italian authorities? What internal proprietary DeepSeek data was found online? What is "DeepSeek" anyway? Why do we care, and what does it mean? Did Microsoft just make OpenAI's strong model available for free? Google explains how generative AI can be and is being misused. An actively exploited and unpatched Zyxel router vulnerability.

SN 1008: HOTP and TOTP - SyncThing, Auto-Updates, Sci-Fi Recs
2
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.

Is AI the Wizard of Oz? Or is it more? Microsoft's long standing effective MFA login bypass. Is TPM 2.0 not required after all for Windows 11? Meet 14 North Korean IT workers who made $88 million from the West. Android updates its Bluetooth tracking with anti-tracking. The NPM package manager repository has had 540,000 malicious packages discovered hiding in plain sight. The AskWoody site remains alive, well, and terrific. My iPhone is linked to Windows and it's wonderful. Yay. How has email been finding logos before BIMI? If we use Him and Her for people, how about Hal for AI? Another very disturbing conversation with ChatGPT. What's going on with the new ChatGPT o1 model? It wants to escape? What??

SN 1004: A Chat with GPT - China's Telecom Hack, Microsoft Activation Cracked, Coding with ChatGPT 4o
2
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. Let's hope something comes of it. GRC's email finally gets BIMI. (Can you see the Ruby-G logo?) Lot's a terrific listener feedback about authenticator policy, a new and free point-to-point link service, Tor's "Snowflake", linking PCs and Smartphones, and even recharging spent SodaStream canisters.
