0xBlock

0xBlock operates within the DeFi space, positioning itself as a transparent and secure staking and crypto investment platform. The application handles minting contracts, daily reward distribution, and user interactions tied to digital assets.

Given the financial nature of the platform, security risks could directly impact:

• User funds and staking contracts
• Wallet integrations
• Backend web application logic
• Access control mechanisms
• Transaction handling processes

DeFi platforms are frequent targets for targeted attacks. 0xBlock required a structured penetration test to assess its exposure to malicious actors and evaluate the effectiveness of its defensive controls.

Cyrex conducted a comprehensive penetration testing engagement simulating a realistic targeted attack.

We were granted:

• Full access to the application
• Regular user-level privileges
• Visibility into platform functionality

Our objective was to evaluate whether a remote attacker could:

• Penetrate application defenses
• Escalate privileges
• Manipulate sensitive workflows
• Exploit weaknesses in access controls or business logic

Testing was conducted under controlled conditions, replicating attacker behavior while maintaining system integrity.

The penetration testing process aimed to:

• Identify exploitable vulnerabilities
• Evaluate potential breach impact
• Assess likelihood of successful compromise
• Provide prioritized remediation guidance

Findings were documented with clear technical recommendations to strengthen platform security.

Following remediation efforts, Cyrex performed structured regression testing to:

• Confirm vulnerabilities were properly resolved
• Ensure patches did not introduce new weaknesses
• Validate the stability of updated security controls

This ensured the integrity of the platform post-remediation.
