Autheo engaged Halborn to conduct a security assessment on their app chain module beginning on January 13th, 2025 and ending on January 23rd, 2025. The security assessment was scoped to the Cosmos-SDK Golang application provided to the Halborn team. Commit hashes and further details can be found in the Scope section of this report.
The team at Halborn was provided two weeks for the engagement and assigned two full-time security engineers to assess the security of the Autheo platform. The security engineers are blockchain and smart-contract security experts with advanced penetration testing and smart-contract hacking experience, and deep knowledge of multiple blockchain protocols.
The purpose of this assessment is to:
Ensure that the Golang components and Smart Contracts operate as intended.
Identify potential security issues with the Cosmos application and Smart Contracts in scope.
In summary, Halborn identified some improvements to reduce the likelihood and impact of risks, which were partially addressed by the Autheo team. The main ones were the following:
Lock the pragma version to the same version used during development and testing.
Modify the SetGuageWithLabels function in the telemetry package to accept the float64 data type.
Halborn performed a combination of manual and automated security testing to balance efficiency, timeliness, practicality, and accuracy in regard to the scope of the custom modules. While manual testing is recommended to uncover flaws in logic, process, and implementation; automated testing techniques help enhance coverage of structures and can quickly identify items that do not follow security best practices. The following phases and associated tools were used throughout the term of the assessment :
Research into architecture and purpose.
Static Analysis of security for scoped repository, and imported functions. (e.g., staticcheck, gosec...)
Manual Assessment for discovering security vulnerabilities on the codebase.
Ensuring the correctness of the codebase.
Dynamic Analysis of files and modules in scope.

Halborn strongly recommends conducting a follow-up assessment of the project either within six months or immediately following any material changes to the codebase, whichever comes first. This approach is crucial for maintaining the project’s integrity and addressing potential vulnerabilities introduced by code modifications.
