Frozen Flame

Frozen Flame is an open-world fantasy MMORPG developed using Unreal Engine 4 networking. With deep progression systems, crafting mechanics, and multiplayer faction play, the title relies on robust server-side validation and secure live services.

For Dreamside Interactive, the objective was to validate the game’s resilience against real-world attack scenarios before malicious actors could exploit gameplay systems.

The scope included:

• Resource gathering systems
• Crafting mechanics (weapons, armor, housing)
• Leveling and trait progression
• Combat abilities and skill trees
• Physics systems (movement, gliding, flying, combat)
• Friend, party, and guild functionality
• Faction systems

In MMORPG environments, vulnerabilities in progression, combat, or social systems can impact both economy balance and player trust.

Cyrex conducted comprehensive black box penetration testing, simulating real-world attacker conditions without internal source code access.

This methodology evaluates exposed services and gameplay flows from the perspective of an external malicious actor.

Leveraging our familiarity with Unreal Engine networking protocols, Cyrex quickly mapped gameplay flows and identified critical interaction points.

We tested:

• Server-side validation of player movement and combat actions
• Crafting and item creation logic
• Progression and trait enforcement mechanisms
• Social system interactions (guilds, parties, factions)

The objective was to determine whether gameplay actions could be manipulated or improperly authorized.

During testing, Cyrex identified several unique vulnerabilities, some deemed critical by the client’s technical team.

We delivered:

• A comprehensive security report
• Proof-of-concept exploitation scenarios
• Prioritized remediation guidance

This enabled Dreamside Interactive to patch vulnerabilities before they could be exploited in production.
