Star Wars: Squadrons Cracked After Five Years, Denuvo Defeated

Star Wars: Squadrons – Cracking Analysis

On November 15, 2025, a crack of Electronic Arts’ Star Wars: Squadrons, protected by Denuvo anti-tamper technology, was released by the user “voices38”. This analysis will delve into the technical aspects of this cracking process, focusing on the potential techniques and challenges involved in bypassing Denuvo and other anti-cheat measures.

Vulnerability Summary

This is not a specific vulnerability report in the traditional sense, as it doesn’t involve a software flaw. Instead, it concerns the circumvention of security controls implemented to protect software from unauthorized access and modification. The “attack vector” here is the reverse engineering of the game’s executable and associated protection mechanisms. The primary targets of the crack were the Denuvo anti-tamper system, the Easy Anti-Cheat software, and the EA App.

Technical Analysis

The Denuvo system employs several techniques to prevent software piracy, including:

• Encryption and Obfuscation: The executable is heavily encrypted and obfuscated to make reverse engineering difficult (T1027). This can involve code transformations, control flow flattening, and other techniques to hinder static and dynamic analysis.
• License Validation: Denuvo requires the game to periodically contact a licensing server to validate the user’s entitlement. Bypassing this typically involves emulating or patching out these network calls (T1199).
• Integrity Checks: Denuvo constantly monitors the game’s code and data for modifications. This involves checksums, hash verifications, and other methods to detect tampering (T1040).

The cracking process likely involved:

• Reverse Engineering: The use of disassemblers (e.g., IDA Pro, Ghidra) and debuggers (e.g., x64dbg) to analyze the game’s executable. This would be necessary to understand how Denuvo functions and identify the points to target for patching.
• Patching: The modification of the game’s code to bypass Denuvo’s checks. This could include removing or altering the license validation calls, disabling integrity checks, or injecting custom code.
• Keygen/Emulation (if applicable): Depending on the specific Denuvo implementation, the cracker might have needed to create a key generator to generate valid licenses or emulate the licensing server.
• Anti-Cheat Bypass: Easy Anti-Cheat (EAC) and the EA App also contain security measures. Bypassing EAC often involves identifying and disabling its hooks and protections within the game’s code. Techniques might include patching the EAC driver or modifying game data. (T1055.001)

The successful crack indicates that voices38 identified the weak points in these protections and developed a method to circumvent them.

Proof of Concept (Conceptual)

A hypothetical proof of concept would involve the following steps:

1. Identify Denuvo functions: Use a disassembler to locate the functions related to Denuvo’s license checks and integrity verification. Function names might be obfuscated, so analysis of cross-references and data flow would be crucial.
2. Isolate and Patch Licensing Calls: Identify the calls to network functions to validate the license. Patch those calls to always return a success status, effectively bypassing the license check. (T1055.011)
3. Disable Integrity Checks: Locate the code responsible for calculating checksums or validating data integrity. Modify this code to either disable the checks entirely or force it to pass regardless of modifications.
4. Bypass Anti-Cheat: Analyze the integration of Easy Anti-Cheat and identify the functions and data structures involved. Patch the code to disable the EAC hooks or to prevent the cheat protection from functioning.
5. Testing: Thoroughly test the cracked executable to ensure that all anti-tamper and anti-cheat measures are bypassed and that the game functions correctly.

Detection Opportunities

While direct detection of the crack itself is difficult, several behavioral indicators might suggest the presence of a cracked game or system compromise (T1548.001):

• Modified Executables: Check the file hashes and timestamps of the game’s executable. A discrepancy from the original, legitimate files is a key indicator. (T1574.002)
• Unusual Network Traffic: Look for network activity that circumvents the game’s normal communication channels. In a legitimate installation, the game should only contact official game servers; a cracked version could communicate with illegitimate licensing servers or key generators. (T1071.001)
• Suspicious Processes: Monitor for processes associated with key generators or patchers that might be used to activate the game. (T1059.001)
• Anti-Cheat Alerts: If the game includes an anti-cheat system, investigate any generated alerts or bans, which could point to a cracked version attempting to bypass anti-cheat measures.
• File Integrity Monitoring: Implement file integrity monitoring (FIM) to detect unauthorized modifications to game files. This can alert administrators to potential compromise. (T1004)

Further analysis of the crack and its techniques would provide a deeper understanding of the specific methods employed, allowing for the development of more targeted detection rules.
