The internal source code employs heavy obfuscation and dynamic memory encryption. Even if a hacker dumps the game's memory while it is running, the data appears as scrambled nonsense.
To prevent similar incidents in the future, game developers can follow best practices for source code security, including:
One of the most notable proprietary systems embedded within Valorant's internal source code is the mechanics. Traditional shooters send location data for all players across the map to every client computer. Valorant's server code calculates visibility dynamically. If an enemy player is behind a solid wall and completely out of line-of-sight, the server explicitly withholds that player's spatial coordinates from the client's memory. This prevents basic wallhacks from reading position data before a player enters view. 2. Riot Vanguard: The Kernel-Level Security Subsystem
While many players know Valorant runs on , the "internal source" is far from a stock installation. Riot Games heavily modified the engine to achieve two primary goals: Valorant Internal Source Code
One of the most innovative aspects of the Valorant internal source code is its server-side "Fog of War" system, designed specifically to combat wallhacks (ESP).
Despite its rigorous design, Vanguard is not flawless. Security researchers are constantly probing its defenses. One notable case involved a bug that earned a . The researcher discovered a design flaw involving Windows' ObRegisterCallbacks API, which Vanguard used to protect its processes. By exploiting a race condition during process creation, they were able to obtain a full-privileged process handle to a protected game process, a critical vulnerability for cheat development. This cat-and-mouse dynamic is permanent; every patch from Riot is met with renewed attempts from the community to find the next vulnerability.
: The game is built on Unreal Engine 4 , specifically utilizing customized versions of UE 4.26 to optimize server performance and replication. The internal source code employs heavy obfuscation and

In the high-stakes world of competitive gaming, anti-cheat is not an afterthought; it is a central feature. For Valorant , this role is filled by , a piece of software that has been both praised for its effectiveness and criticized for its intrusiveness.
The battle over proprietary source code is fought in courtrooms just as intensely as it is fought in cyber environments. Riot Games and its peers employ aggressive legal strategies to protect their ecosystems. Traditional shooters send location data for all players
In January 2023, Riot Games confirmed that its systems were compromised through a social engineering attack. The hackers successfully exfiltrated source code for several projects, including Valorant (specifically its legacy anti-cheat systems) and League of Legends .
If the source code were public, malicious actors could find "buffer overflows" or memory vulnerabilities to crash servers or gain administrative privileges.
