Discord

Introduction

Discord is a popular communication platform used by many CTFs for announcements, challenges, or hidden flags. Links and files from Discord can reveal useful data even if the invite or message is inactive.

This page covers how to interpret Discord links, and work with snowflake IDs.

Discord Links and Structure

Discord resources (guilds, channels, messages) are identified by numeric IDs called Snowflakes. These IDs encode both a timestamp and unique object ID bits.

Common URL Patterns

Purpose	Example URL Structure
Guild / Server	`https://discord.com/channels/<guild_id>`
Channel	`https://discord.com/channels/<guild_id>/<channel_id>`
Specific Message	`https://discord.com/channels/<guild_id>/<channel_id>/<message_id>`
Invite Link	`https://discord.gg/<invite_code>`

An invalid or expired link may still leak IDs that can be decoded to determine when the guild/channel/message was created.
