    Obligatory dns tunnel software for exfil. It is super noisy if you do dns querylogging, so I'd not use it for anything major, but it is a fun research tool.

    It’s slow, but it works and is a handy “last resort” tool.

  • Russia starts blocking VPN at the protocol (WireGuard, OpenVPN) level

    While working in an environment where VPN connections were pretty much all blocked⁰ a friend of mine had success using to access a remote machine¹. Not quite the same as a direct VPN connection but worth a try if nothing else functions, it looks enough like normal HTTPS traffic that he got away with it.

    To keep your wireguard setup more as-is, you could try to tunnel that via a web server. In fact which that uses could be used just as well with any other UDP based VPN.

    I once tinkered with and successfully connected to resources over the wireless on a train, bypassing its traffic capture and sign-up requirement, so that might be an option, though I think fully blocking external DNS is more common now so this is less likely to work²³.


    [0] practically only HTTP(S) permitted, not even SSH, DPI in use that detected just using SSH or OpenVPN over port 443

    [1] NOTE: be careful breaching restrictions like this, you are at risk of an insta-sacking if discovered, or worse if operating in some securiry environments!

    [2] and the latency when it does work is significant!

    [3] and that much traffic over port 53 might get noticed by the heuristics of data exfiltration scanner, encouraging sysadmins to notice and implement a way to block it

  • Show HN: File distribution over DNS: (ab)using DNS as a CDN
    2 projects | | 31 Jul 2023
    There's also iodine, a C program that tunnels IPv4 packets over DNS. Useful for bypassing captive portals on wifi, since DNS usually isn't restricted.

    Regarding cloudflare DNS over HTTPS: It could be that it tries to server data encoded as JSON, which is impossible in JSON. Some control characters and bytes 128-255 cannot be represented as JSON strings.

    A regular proxy on port 53 might work? Is it necessary to actually use DNS?

    Otherwise there's

    Well, you're really exhausting your options here (and possibly your IT department's patience). Iodine would still be an option, it creates a tunnel through DNS traffic. Nearly impossible to block/filter out but you shouldn't expect a lot of bandwidth. Try it out! Although if you're only going to use low-bandwidth applications through the tunnel anyway you might as well use your own mobile data plan instead of your school's WLAN.
