  • Most large corporations’ tech leaders don’t actually have any idea how tech works. They are being told that if they don’t have an AI plan their company will be obsoleted by their competitors that do; often by AI “experts” that also don’t have the slightest understanding of how LLMs actually work. And without that understanding companies are rushing to use AI to solve problems that AI can’t solve.

    AI is not smart, it’s not magic, it can’t “think”, it can’t “reason” (despite what Open AI marketing claims) it’s just math that measures how well something fits the pattern of the examples it was trained on. Generative AIs like ChatGPT work by simply considering every possible word that could come next and ranking them by which one best matches the pattern.

    If the input doesn’t resemble a pattern it was trained on, the best ranked response might be complete nonsense. ChatGPT was trained on enough examples that for anything you ask it there was probably something similar in its training dataset so it seems smarter than it is, but at the end of the day, it’s still just pattern matching.

    If a company’s AI strategy is based on the assumption that AI can do what its marketing claims. We’re going to keep seeing these kinds of humorous failures.

    AI (for now at least) can’t replace a human in any role that requires any degree of cognitive thinking skills… Of course we might be surprised at how few jobs actually require cognitive thinking skills. Given the current AI hypewagon, apparently CTO is one of those jobs that doesn’t require cognitive thinking skills.





  • Yes you’re correct. I will qualify my previous statement as hydrogen powered road vehicles don’t make sense for now.

    The problem at the moment is that electricity generation is not carbon free and in most countries not even close.

    Unfortunately the transition to a carbon free electric grid is being significantly retarded by policymakers that are, as you say, myopic. As a result it will be at least two more decades before hydrogen makes sense.

    The carbon footprint of lithium battery manufacturing, is small compared to the carbon footprint of electricity generation. Until that changes significantly lithium batteries will continue to be a better choice than hydrogen fuel cell.

    Hydrogen may make sense in a future where we’ve eliminated all fossil fuel electricity generation and there’s an abundance of carbon free electricity that can be used to create green hydrogen as a form of energy storage. Though by the time that point comes, we may have developed battery technology or some other energy storage technology that doesn’t carry the same carbon footprint that lithium ion does today.


  • Hydrogen doesn’t make sense and never did as a strategy to reduce greenhouse gas emissions in vehicles.

    Most hydrogen is made from fossil fuels, and has a lot of emissions during manufacturing. But even green hydrogen, which is made by using carbon free generated electricity to split water into hydrogen and oxygen doesn’t make sense.

    If you’ve build new renewable power it’s more efficient to use it to charge batteries than to use it to generate hydrogen.

    There might be a case for compressed hydrogen, In vehicles where batteries are too heavy like aircraft.

    But for road vehicles, batteries are more effective at reducing emission.

    If you’re building any new renewable power, you’ll reduce more emissions by using it to displace coal power, the to generate green hydrogen.

    Some day when we’ve eliminated fossil fuel based electricity generation, Green hydrogen might start to make sense. But anybody trying to do it right now is not being as helpful as they could be.




  • You wouldn’t be able to MITM a plaintext connection inside a corporate network with this attack by itself. You could only MITM something that the attacker can access without your VPN.

    Any corporate network that has an unsecure, publicly accessible endpoint that prompts for credentials is begging to be hacked with or without this attack.

    Now you could spoof an login screen with this attack if you had detailed info on the corporate network you’re targeting. But it would need to be a login page that doesn’t use HTTPS (any corporations, dumb enough to do that this day and age are begging to be hacked), or you’d need the user to ignore the browser warning about it not being secure, which that is possible.


  • I can’t see routing traffic to some kind of local presence and then routing back to the target machine to route out through the tunnel adapter without a successful compromise of at least one other vulnerability.

    That’s not to say there’s nothing you could do… I could see some kind of social engineering attack maybe… leaked traffic redirects to a local web server that presents a fake authentication screen that phishes credentials , or something like that. I could only see that working in a very targeted situation… would have to be something more than just a some rouge public wi-fi. They’d have to have some prior knowledge of the private network the target was connecting to.



  • Not all VPN traffic. Only traffic that would be routable without a VPN.

    This works by tricking the computer into routing traffic to the attacker’s gateway instead of the VPN’s gateway. It doesn’t give the attacker access to the VPN gateway.

    So traffic intended for a private network that is only accessible via VPN (like if you were connecting to a corporate network for example) wouldn’t be compromised. You simply wouldn’t be able to connect through the attacker’s gateway to the private network, and there wouldn’t be traffic to intercept.

    This attack doesn’t break TLS encryption either. Anything you access over https (which is the vast majority of the internet these days) would still be just as encrypted as if you weren’t using a VPN.

    For most people, in most scenarios, this amount to a small invasion of privacy. Our hypothetical malicious coffee shop could tell the ip addresses of websites you’re visiting, but probably not what you’re doing on those websites, unless it was an insecure website to begin with. Which is the case with or with VPN.

    For some people or some situations that is a MASSIVE concern. People who use VPNs to hide what they’re doing from state level actors come to mind.

    But for the average person who’s just using a VPN because they’re privacy conscious, or because they’re location spoofing. This is not going to represent a significant risk.


  • So for this attack to work, the attacker needs to be able to run a malicious DHCP server on the target machine’s network.

    Meaning they need to have already compromised your local network either physically in person or by compromising a device on that network. If you’ve gotten that far you can already do a lot of damage without this attack.

    For the average person this is yet another non-issue. But if you regularly use a VPN over untrusted networks like a hotel or coffee shop wifi then, in theory, an attacker could get your traffic to route outside the VPN tunnel.



  • I think I have you slightly beat… mine was an Apple II+, circa late 1981, with a disk drive, and a monochrome green screen monitor.

    First cell phone was around 1997. Though I honestly don’t remember what it was. I recall having a Nokia model from before they made that indestructible model in all the memes, as well as a Kyocera one that I could connect to a laptop and have wireless dial up internet at some abysmal speed like 20 kbps. (0.02 mbps). I had at least two more phones, including a Treo 650 “smartphone” before getting my first iPhone, a 3G. I’m on my sixth iPhone now.



  • Who cares? Because I assure you, Microsoft doesn’t.

    20-25% of those webservers are running on Microsoft Azure hardware. Microsoft is the #2 cloud provider and has been slowly but closing their gap behind AWS in recent years. All of that is in large part due to them embracing Linux and open source support on their platform.

    Software isn’t the battleground, and hasn’t been for a decade. The people behind Apache and Nginx aren’t making bank on their web server dominance. Microsoft and AWS still rake in money hand over fist regardless of what software runs on their servers.

    The author of this article’s apparent attitude that this is some kind of indicator of Microsoft’s market failure is one of the most ridiculous conclusions I’ve heard in a while.
