Suicide Squad: Kill the Justice League

Suicide Squad: Kill the Justice League is a high-profile action-adventure shooter set in the DC Universe. Built on Unreal Engine 4 and spanning PC and console platforms, the title combines fast-paced combat with live service elements and multiplayer systems.

For Rocksteady Studios and Warner Bros., security validation was critical.

The attack surface included:

• Unreal Engine 4 networking implementations
• Cross-platform gameplay systems
• Live services infrastructure
• In-game currency and reward logic
• Matchmaking and social systems

In a shooter built around combat precision, progression systems, and online interactions, vulnerabilities in gameplay validation or service logic can affect fairness, player trust, and platform stability. The team required a partner capable of reviewing internal systems directly and identifying weaknesses before release.

Cyrex conducted comprehensive white box penetration testing, working with visibility into internal implementations to assess security at the code and architecture level.

This approach enabled targeted validation of gameplay logic, networking flows, and service integrations.

Given the title's foundation on Unreal Engine 4, our assessment included:

• UE4 networking and replication mechanisms
• Server-side validation of player actions
• Real-time combat and movement logic
• Data handling between client and backend services

We evaluated how gameplay actions were processed and ensured server authority was enforced across multiplayer interactions.

As the game spans PC and console platforms, we reviewed:

• Platform-specific security considerations
• Live services architecture
• Matchmaking flows
• Clan and invitation systems
• Social interactions

The objective was to validate consistent security posture across environments and prevent discrepancies that could introduce exploit vectors.

Our white box testing extended into gameplay-critical systems, including:

• Physics and character movement
• Shooting mechanics
• Reward systems
• In-game currency logic
• Weapons and item systems
• Points and upgrade systems

Each component was assessed for improper trust assumptions, logic flaws, or manipulation opportunities that could impact progression or competitive balance.

White box access allowed vulnerabilities to be traced directly to implementation logic, providing precise remediation guidance.
