A national security storm is swirling around the world’s most valuable chipmaker, a new AI model has uncovered a thousand-plus weak spots in the software that runs much of the internet, and millions of cheap TV boxes shipped with a backdoor built right in. On this week’s Tech Talk Tuesday on the Mark Reardon Show, 97.1 FM Talk, ThrottleNet owner George Rosenthal broke down what these stories mean for the AI race and for your home network, shared an easy way to lock down your smart devices, and previewed an Apple Watch feature that listens to conversations.

The Nvidia Story and Why the AI Chip Race Is a National Security Issue
George opened with the story dominating headlines. According to a New York Times report, U.S. officials believe an executive at Megaspeed, a Singapore-based data center company that buys Nvidia’s AI chips, was a Chinese intelligence asset who developed a close relationship with Nvidia CEO Jensen Huang. The reporting relies on anonymous officials, and much of it remains unconfirmed.
Here is where things stand, based on the reporting:
- Nvidia’s response: The company says Huang’s interactions with the executive were “not unusual or unexpected,” that Megaspeed is an ordinary regional customer, and that earlier allegations of chip diversion were investigated and debunked.
- Nvidia’s board: Independent directors, working with outside legal counsel, have opened a review. The board says it has no reason to believe company secrets or U.S. national security were compromised.
- Washington: Members of Congress have requested a closed-door briefing, and federal investigators have examined Megaspeed over suspicions that advanced chips were diverted to China. No wrongdoing has been established publicly.
- Beijing: China’s government has called the accusations groundless.
George’s take is about the bigger picture. In his view, the U.S. is in a cold war with China over AI, and the advanced chips Nvidia makes are a major reason America leads. He argued that regulators, Congress, and the Justice Department all weighing in shows how high the stakes are, and that the real question is who ended up with these chips and who controls the technology behind them. He also reiterated that the country needs to build the data centers to compete in this race.
His advice for business leaders is simple: if someone you barely know suddenly takes a strong interest in you, be careful what you share.
An AI Found More Than 1,000 Weak Spots in Linux and Firefox
Next, George covered a cybersecurity milestone. OpenAI’s new GPT-6 Cyber model is not available to the public. Only select approved cybersecurity customers are testing it. In that testing, it reportedly identified 81 previously unknown high-severity flaws in the Firefox web browser, and it flagged thousands of potential security issues in Linux, with working exploits developed for 948 of them. The figures come from OpenAI’s own announcement, and Mozilla has already released patches for many of the Firefox issues.
George explained why Linux matters. It’s an open-source operating system, similar to Windows or macOS, but anyone can build on it. It quietly powers a huge share of the internet, along with the devices in your home, like routers, smart TVs, and Android phones. The good news, he said, is that an AI found these problems before criminals could exploit them. The sobering part is that attackers will eventually have similar tools, and it will take time to patch everything that was found.
George’s guidance:
- Update everything as often as you can. Don’t wait six months to install patches, and make sure your browsers, including Firefox, are up to date.
- Business owners: build a regular patching routine rather than updating only when something breaks.
- Put smart gadgets on a guest Wi-Fi network, as described below.
Cheap TV Boxes With a Backdoor Built In
George then warned about a story that should make anyone think twice about bargain streaming devices. Google has taken action against Videostrong, a Chinese manufacturer that made Android TV boxes sold as Google certified. Google says Videostrong built a backdoor into its devices, and early reports estimated about 1.3 million boxes were being used by criminals. Google has since said that shutting down the servers behind the operation will cut off access to at least 10 million additional compromised devices. It has banned Videostrong from selling certified Android products and says it is updating its review process, since the malicious code loaded after the first startup and slipped past testing.
George pointed out that a backdoor like this gives attackers a path onto the Wi-Fi network the box is connected to. He said updating the boxes didn’t solve the problem because the backdoor was built into the software, and noted that the manufacturer could sell that access to others. Google’s takedown should leave affected devices safe to use, though owners may still want to consider replacing them.
His advice:
- Skip no-name TV boxes. Stick with established, legitimate products such as a Roku, Amazon Fire TV Stick, or Apple TV.
- Remember what you’re buying. A streaming box sits inside your home network, so it’s worth paying a bit more for a trustworthy brand.
As for legal recourse, George was blunt: when the company is tied to a government like China’s, there isn’t much to be done after the fact. Keeping these devices out of your home in the first place is the best defense.
How to Set Up Guest Wi-Fi for Your Smart Devices
George’s most practical tip of the day was a repeat of advice he’s given before, because it protects against a lot of the threats above: put your smart devices on a guest Wi-Fi network, separate from your main one. That includes cameras, security systems, TVs, refrigerators, thermostats, and smart picture frames, which download images from the cloud and are easy to break into. Attackers rarely care about your photos. They want a foothold on your network.
His steps:
- Check your router’s age. If it’s more than five years old, replace it. Newer routers include security updates and faster Wi-Fi, including Wi-Fi 7.
- Open the router’s admin panel. Not sure how? George suggests taking a photo of your router and asking an AI assistant how to access the admin panel. It can identify the model and walk you through it.
- Create a guest network with a fairly complicated password.
- Move your smart devices over, one by one. Keep laptops, work computers, and gaming PCs on your main network.
Apple Watch’s New Feature: Conversation “Rewind” and Recaps
George wrapped up with Apple news that might surprise people at first but, in his view, isn’t as alarming as it sounds. The watchOS 27.3 beta, which began testing this month, adds two features for the Apple Watch Series 12 and Ultra 4, paired with an iPhone that supports Apple Intelligence:
- Live Rewind: Double-press the Digital Crown to see a text snippet of what was just said. Apple says it covers the last 15 seconds, and unsaved snippets are discarded quickly.
- Siri Recap: Creates a short summary of a conversation, such as dates, deadlines, or prices. Apple says it doesn’t save raw audio, identify speakers, or provide word-for-word transcripts, and unsaved recaps are deleted after seven days.
George emphasized that the features are off by default and that you have to turn them on in settings. He credits Apple for taking a privacy-first approach, and noted that audio isn’t saved permanently. Apple says conversations are processed on the device, and that recaps are generated using its Private Cloud Compute system and deleted from there immediately afterward. George expects similar features to come to the iPhone eventually. The feature is in beta now, with a public release planned for later.
The Bottom Line
From national security to the TV in your living room, this week’s stories point to the same lessons: keep everything updated, be careful what you buy and connect to your network, and put your smart devices on their own guest Wi-Fi. As AI tools get better at finding weaknesses, staying on top of the basics matters more than ever.
