  • If you use HTTPS, the attacker can still see what websites you connect to, they just can’t see what you are sending or receiving. So basically they can steal your browsing history, which defeats the purpose of a commercial VPN for many users.

    This is blatantly false. They can see IP addresses and ports of you connect to from IP packets, and hostnames from TLS negotiation phase (and DNS requests if you don’t use custom DNS settings). HTTP data is fully encrypted when using HTTPS.

    If exposing hostnames and IP addresses is dangerous, chances are that establishing a VPN connection is as dangerous.


  • Control of the DHCP server in the victim’s network is required for the attack to work.

    This is not a VPN vulnerability, but a lower level networking setup manipulation that negates naive VPN setups by instructing your OS to send traffic outside of VPN tunnel.

    In conclusion, if your VPN setup doesn’t include routing guards or an indirection layer, ISP controlled routers and public WiFis will make you drop out of the tunnel now that there’s a simple video instruction out there.












  • It’s because Unix was created by engineers rather than by ui/ux design professionals.

    This is somewhat disingenuous. Unix terminal is one of the most ergonomic tools out there. It is not “designed by engineers”, it is engineered for a purpose with user training in mind.

    Ergonomics is engineering. UI/UX design is engineering. UX designer that doesn’t apply engineering method is called an artist.


  • Entropy is a measure of a number of distinct possible configurations that result in an equivalent outcome.

    It’s pure statistics. Given time symmetric laws of nature and a state that can be achieved by a relatively small number of configurations, in the absence of potential barriers, the system inevitably approaches a state that’s achievable by a larger number of configurations. Simply because an elementary change is more likely to fall into the latter mode. Thus, arrow of time emerges.




  • I described a route to spoof DNS root authority that Russia and China can use already. Single root is not an advantage, it’s merely a different kind of implementation with different attack vectors.

    When it comes to security, it is better to have multiple different implementations coalesce at a point of service delivery, than have a single source of truth. If everything is delivered via DNS, there’s your tasty target for a capable adversary. If there are multiple verification mechanisms, it’s easier to tailor an attack for a specific target.

    I want cryptographic infrastructure I rely on to be the last resort for anyone capable of dealing with it.
