Mohamed Elyousfi engineered robust backend and security features across the Ostorlab/oxo, Ostorlab/agent_asteroid, and Ostorlab/agent_whatweb repositories, focusing on asset management, vulnerability detection, and automation. He implemented URL-based asset ingestion, configurable scan timeouts, and deterministic service naming, using Python and Docker to streamline scan operations and reduce operational risk. Mohamed expanded fingerprinting coverage and exploit modules, integrating Nuclei templating and plugin-based detection for improved vulnerability assessment. His work emphasized maintainability through code refactoring, dependency management, and comprehensive unit testing, resulting in more reliable CI/CD pipelines, safer deprecation handling, and enhanced documentation for privacy and security best practices.

In Oct 2025, delivered key reliability and security improvements across Ostorlab/oxo and Ostorlab/KB. Implemented deterministic service naming to prevent Docker API errors, added explicit length validation with ServiceNameTooLong feedback, prepared release readiness via submodule updates and version bump to 1.7.12, expanded security guidance documentation for iOS minimum versions, and cleaned up the codebase to reduce debt. These changes reduce production incidents, improve developer feedback, and strengthen security posture while maintaining release velocity.
