  • I have set it up in a way where all the packets have to go through their VPN and if they don’t, they get dropped before they leave my PC.

    That is the function of a firewall and not of the VPN. As I understand portmaster it does both. But that is not normal VPN behavior.

    VPNs are not magic. They are a piece of software that encrypt traffic and send it to a special server. They do that by creating a virtual Internet connection (think like pluging in an additional Ethernet cable or connection to an addition WiFi at the same time). Everything that is sent through the virtual connection is encrypted. Your system now has (at least) two valid Internet connections (one real and one virtual). For every packet it sends it needs to decide which connection it should send it from. This is decided by something called the routing table. When you start the VPN it will put two routes into the table.

    • traffic going to the VPN server goes through the real connection (so the encrypted VPN traffic is routed correctly)
    • everything else goes through the virtual connection (the VPN tunnel where it gets encrypted)

    The attack described is a way how a network router can add a new route into your devices routing table to basically override the second route from the VPN. The route is still there, there just is another one that has a higher priority.

    A VPN is not the ultimate authority over your network traffic. It is just another program sending and recieving taffic.




  • Wait so without the option it checks against the system trust store and with the option it does exactly the same (but may also includes an additional CA if that was passed as the argument)?

    This should be a cve. There is a security feature. It does not work as documented. That’s a vulnerability. That should get a cve.

  • They sometimes buy keys using stolen credit cards. When the fraud is found out, the banks will request the money from the developer. They in turn often don’t have a way to lock the fraudulent key, so it remains valid.

    The costs for the initial bank transfer, plus the time invested in returning the money to the credit card holder are payed by the developer.

    The key reseller has a 100% profit margin, the customer has a valid and cheap game key, and the developer actually lost time and money.
