A Minecraft survival server was taken offline after a strange storage incident near one of the older bases.
The players claimed that nothing important was written in chat, and the visible server files do not immediately reveal anything unusual. Before the backup was handed over, the admin left a note suggesting that the real evidence was not in the chat logs, but somewhere inside the world itself.
#Objective
Objective
Inspect the recovered server backup, determine how the hidden information was stored within the world data, and recover the flag.
#Files
| File | Description |
|---|---|
server.properties | Server configuration |
whitelist.json | Player whitelist |
logs/latest.log | Server log file |
world/level.dat | Minecraft world metadata |
#Getting Started
Everything required to solve the challenge is already included in the provided backup. The logs may help you identify where to begin, but they are not the final source of the flag.
Focus on understanding how Minecraft stores world data beyond what is immediately visible.
#Notes
- Minecraft worlds can store much more than visible blocks.
- If you discover a collection of similar records, consider whether they represent a sequence rather than ordinary inventory contents.
- Some objects may appear repetitive or out of place. Their metadata may be more important than their visible contents.
- Not every useful clue appears as a chat message. Metadata can be just as valuable as the items themselves.
#Flag
Submit the complete flag in the format
rvcectf{...}.
Good luck!
