SN 1011: Jailbreaking AI - Deepseek, "ROUTERS" Act, Zyxel Vulnerability
Loading
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. The new US "ROUTERS" Act. Is pirate-site blocking legislation justified or is it censorship? Russia's blocked website count tops 400,000. Microsoft adds "scareware" warnings to Edge. Bitwarden improves account security. What's still my favorite disk imaging tool?

SN 1009: Attacking TOTP - Force-Installed Outlook, DJI Firmware Update
2
What do we learn from January's record breaking 0-day critical Patch Tuesday? Microsoft to "force-install" a new Outlook into all Windows 10 and 11 desktops? GoDaddy required to get much more serious about its hosting security. More age verification enforcement is coming, including globally. What another instance of a widely exposed management interface teaches us. DJI drone's official firmware update lifts geofencing for unrestricted flight. CISA's efforts pay off with MUCH improved critical infrastructure security. Listener feedback about TOTP, HOTP and age-verification.

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.

SN 1005: 6-Day Certificates? Why? - Android Anti-Tracking, MFA lLogin Bypass, BIMI
2
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?? Let's Encrypt plans to reduce its certificate lifetime from 90 to just 6 days. Why in the world? And all the best holiday wishes.

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. Then we look at a recent conversation Steve had with "ChatGPT 4o with canvas" and the new plan that resulted Show Notes - https://www.grc.com/sn/SN-1004-Notes.pdf Hosts: Steve Gibson and Leo Laporte Download or subscribe to Security Now at https://twit.tv/shows/security-now.

Steve Gibson and Leo Laporte discuss Microsoft's clarification about AI training data usage, a fascinating breakthrough in understanding autonomous vehicle vulnerabilities, and an urgent call for help from the Tor Network. The show culminates in an in-depth exploration of NASA's incredible Voyager 1 mission, which continues to communicate with Earth from nearly a light-day away despite increasing technical challenges. Microsoft clarifies they are NOT using customer data from Office apps to train AI models "Digital epileptic seizures" caused by flashing emergency vehicle lights can confuse automated driving systems, posing crash risks Tor Network issues urgent call for volunteers to run new WebTunnel bridges to circumvent censorship in Russia Zello asks its 140 million users to change passwords as a precautionary measure, hinting at a possible data breach FTC opens broad antitrust investigation into Microsoft's business practices across software, cloud, cybersecurity, and AI New Android scareware tactic simulates a seriously cracked and malfunctioning smartphone screen Steve argues it's likely safe to leave Wireguard VPN ports open, but he prefers not to out of an abundance of caution Research shows AI training on AI-generated content can lead to homogeneity and loss of diversity in outputs Australia passes world-first law banning children under 16 from social media, with hefty fines for non-compliant platforms NASA's Voyager 1 probe, nearly a light-day from Earth, resumes operations after a communications scare but faces mounting technical challenges as it nears the end of its life Show Notes - https://www.grc.com/sn/SN-1003-Notes.pdf Hosts: Steve Gibson and Leo Laporte Download or subscribe to Security Now at https://twit.tv/shows/security-now.

What's the new "nearest neighbor" attack and how do you defend against it? Let's Encrypt just turned 10. What changes has it wrought? Now the Coast Guard is worried about Chinese built ship-to-shore cranes. Pakistan becomes the first country to block Bluesky. There's a new way to get Git repos "swatted" and removed. Who's to blame for Palo Alto Networks' serious new 0-day vulnerabilities? If you have any of these six D-Link VPN routers, unplug them immediately! It turns out that VPN apps are against Shariah Law. Who knew? The Return of Windows Recall. What are we learning now? How many of today's systems remain vulnerable to last year's most popular exploits? We share and respond to a bunch of terrific feedback from our listeners. What are Microsoft's "Connected Experience" and why might you choose to disconnect from them?

SN 1001: Artificial General Intelligence (AGI) - Gmail Temp Addresses, Russia's Internet Off Switch
2
How Microsoft lured the US Government into a far deeper and expensive dependency upon its cybersecurity solutions. Gmail to offer native throwaway email aliases like Apple and Mozilla. Russia to ban several additional hosting companies and give its big Internet disconnect switch another test. Russia uses a diabolical Windows flaw to attack Ukrainians. The value of old Security Now episodes. TrueCrypt's successor. Using Cloudflare's Tunnel service for remote network access. How to make a local server appear to be on a remote public IP. How to share an 'impossible to type' password with someone. How to find obscure previous references in the Security Now podcast. What are the parameters for the expected and widely anticipated next generation Artificial General Intelligence (AGI)? What do those in the industry and academia expect?
