[BUG] Suspicious Data Usage

[SyntaxualSugar]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

I noticed unusually high network utilization coming from my server. With some digging, I was able to narrow it down to it originating from the syncthing container. I have updated the container to the latest and after restarting the server and the container, the suspicious data comes back. So, what makes it suspicious? I have nothing configured to use syncthing that lives outside of my LAN, and yet syncthing was pulling ~10mbps (give or take 3mbps) consistently through my WAN connection. It would do this from a seemingly random IP:port combination. If I block one in my firewall then it would keep attempting the connection periodically before swapping to a new IP:port combination. It was always tcp traffic with the destination port (external to my lan) being 443.

Some example IPs that were connected to are: 45.41.204.213, 169.150.197.139, 103.214.71.33, 107.152.39.18.
The ports were always in the 40k-55k range, from what I could tell.

I do not know enough to know if this means the container is compromised, but I will not be running it on my network anymore.

Expected Behavior

It should not be transferring large amounts of data with suspicious WAN connections.

Steps To Reproduce

1. Run the container with this docker compose, where the "external" network is a bridge network.

2. Use your network observation tool of choice to see a spike in traffic attempting to traverse your WAN interface. I used Torch on my mikrotik router.

Thanks for opening your first issue here! Be sure to follow the relevant issue templates, or risk having this issue marked as invalid.

[EphemeralDev]

These are likely syncthing relay servers, three of the four ip addresses you listed appear on https://relays.syncthing.net/. If you use a mobile device it probably switched over to relays once you left your network, or these devices were unable to connect to each other locally.

If you want to disable this behavior you can disable relays in your settings. This forum post covers some of the relevant options.
