OGame
Cyrex partnered with Gameforge to conduct black box penetration testing for OGame, securing browser-based MMO systems including messaging, premium currency, alliance management, and time-based gameplay mechanics.
The Challenge
Securing a Browser-Based MMO with Time-Based Mechanics
OGame is a long-running browser-based MMO focused on empire building, alliance coordination, and large-scale galactic warfare. As a browser title with persistent progression and player-driven systems, its attack surface differs significantly from client-based games.
Key areas of concern included:
- Account registration and authentication
- Alliance creation and management
- Premium currency and shop systems
- Messaging and forum systems
- Player attack actions
- Building upkeep and time-based mechanics
- Research and invention systems
Because gameplay progression is time-based and heavily dependent on economic systems, vulnerabilities in these areas could directly impact balance, player fairness, and platform stability.
Gameforge required a real-world security evaluation to simulate how an external attacker might target these systems.
The Cyrex Solution
Black Box Penetration Testing of Browser & Backend Systems
Cyrex conducted comprehensive black box penetration testing, emulating realistic hacking scenarios without internal documentation or source code access.
As a browser-based MMO, OGame required focused testing on:
- Web application vulnerabilities
- Session handling and authentication flows
- Client-server request validation
- Messaging and forum security
Gameplay & Economic System Assessment
Our engagement included testing of:
- Premium currency handling and shop transactions
- Alliance and player management systems
- Player attack and combat logic
- Time-based building and upkeep mechanics
- Research and invention progression systems
We evaluated whether gameplay actions and economic interactions were properly validated server-side and resistant to tampering.
Messaging & Community System Security
Given OGame’s integrated messaging and forum systems, we also assessed:
- Message injection and abuse vectors
- Authentication boundaries between gameplay and community systems
- Potential exploitation paths within communication features
These systems were reviewed to ensure they could not be leveraged as attack vectors.
Vulnerability Reporting & Iterative Validation
Cyrex worked directly with Gameforge’s technical team, leveraging their internal bug tracking system alongside our comprehensive reporting process.
We delivered:
- Detailed vulnerability documentation
- Risk prioritization
- Actionable remediation guidance
After patching, Cyrex conducted full sanity and regression testing to validate remediation effectiveness and confirm operational security.
The Outcome
Reinforced Browser MMO Security & Economic Integrity
- Identification and remediation of high-priority vulnerabilities
- Improved protection of premium currency and progression systems
- Strengthened messaging and forum security
- Increased resilience against real-world exploitation attempts
