NationStates apopular online government simulation game, has suffered a data breach that led to its temporary shutdown. The company confirmed that an unauthorized user gained access to the production server and copied user data, raising concerns about the security of personal information.
The violation: A player goes over the line
On January 27, 2026, a player discovered a vulnerability in the NationStates app code and, while testing it, exceeded authorized limits. This allowed him to execute remote code (RCE) on the main server and copy user data and the app code to his own system. The game's creator, Max Barry, explained that the individual had previously reported various bugs and received the Bug Hunter badge, but had never been granted access to the production system.

Despite the apology and the claim that the data was deleted, NationStates is treating the data as a breach, as there is no way to verify the player's claims.
The critical error: “Dispatch Search”
The breach was caused by a bug in the new “Dispatch Search”, introduced in September 2025. The attacker exploited insufficient data sanitization and a double-parsing, creating the critical RCE vulnerability. According to NationStates, it was the first time in the history of the site that such an incident had been observed.
The temporary shutdown of the server is considered necessary to fully rebuild it and confirm that it is secure.
NationStates: What kind of data was exposed?
The incident involves the possible exposure of the following:
- Email addresses (including historical accounts)
- Passwords stored as MD5 hashes, an old and inadequate security method
- IP addresses
- Browser UserAgent strings
- Telegrams Data: The game's internal private messaging system was likely exposed to a limited extent
NationStates assures that it does not collect real names, physical addresses, phone numbers, or credit card information.

Troubleshooting and recovery
The site estimates it will be back up and running within 2–5 days , and users will be able to check their country-specific data on the private_info page . The company is reporting the incident to the relevant government authorities and is focusing on:
- Complete reconstruction of the production server on new hardware
- Security checks and improvements
- Password security upgrade
NationStates emphasizes that player trust is critical and that the incident will be used to improve the overall security of the game.
The role of the community and safety lessons
The case highlights a delicate balance: community engagement through the Bug Hunter program is valuable, but exceeding authorizations can lead to serious security incidents. NationStates shows that even small vulnerabilities in popular online gaming can have significant impacts.
