Resource Pack Whitelist

Preventing side-channel IP leakage

When a server sends a resource pack request packet to a client, the client will send an HTTP request to whatever URL the server says the resource pack is hosted at. Because those URLs can be attacker-controlled, a server owner would be able to extract the IP address of any client accepting the server's resource pack.

MineKeep prevents IP leakage from happening this way by employing a resource pack host whitelist. Resource pack requests can only reference packs hosted on a set list of trusted domains. All other requests will be dropped.

Here are the whitelisted domains:

• *.minekeep.dev (self-hosted packs)

• download.mc-packs.net (mc-packs)

• drive.usercontent.google.com (Google Drive)

• github.com (GitHub)

• raw.githubusercontent.com (GitHub)

• atlas.nexomc.com (Nexo)

• atlas.oraxen.com (Oraxen)

• nauticalhosting.org (NauticalRanks)

• lobfile.com (ItemsAdder)

• dropbox.com (Dropbox)

• download*.mediafire.com (MediaFire)

If you need to serve a resource pack. Make sure it originates from one of these domains. Also make sure that the URL you provide leads directly to the download, and not a page with a button that says download. Otherwise Minecraft does not recognise it.
