PROFILE

Mohamed Nasser

Mohamed Nasser developed and enhanced security detection features across several Ostorlab repositories, including agent_whatweb, oxo, and KEV, over a four-month period. He implemented new detection plugins for Cisco ISE and Adminer, focusing on HTTP header and body pattern matching, and improved version recognition logic. In Ostorlab/oxo, Mohamed introduced type hints and refactored mixins for safer, more readable Python code, while also enhancing logging utilities for better debugging. He maintained Docker images and updated documentation in YAML and Markdown, demonstrating skills in containerization, plugin development, and vulnerability detection. His work emphasized maintainability, reliability, and clear, test-driven engineering practices.

October 2025: Delivered feature enhancements and stability improvements across Ostorlab/agent_whatweb and Ostorlab/oxo. Key features: Adminer detection and version recognition in WhatWeb; Docker image maintenance upgrading pip to latest. Major bugs fixed: removal of a redundant log message and improved error handling in the agent. Logging utilities enhancement: added and renamed a formatting helper for log data to format_dict with tests. Impact: higher detection accuracy, more reliable container builds, clearer debugging and observability, enabling faster triage and better security assessments. Technologies demonstrated: Python, Docker, logging utilities, and test-driven development.

July 2025 performance summary for Ostorlab/agent_whatweb. Delivered Cisco ISE detection capabilities through an initial detection plugin with header/body-based matching rules, including user-facing naming ('Cisco ISE'), versioning, and author metadata. Follow-on refactor simplified detection logic by removing Content-Security-Policy header and Server header checks and relying on the presence of 'Cisco Identity Services Engine' within the response body to improve reliability and maintainability. No explicit bug fixes documented this month; primary focus was feature delivery, code quality, and maintainability. Business impact: enhanced detection of Cisco ISE deployments enables faster risk assessment, asset inventory accuracy, and more targeted remediation planning. Technologies/skills demonstrated: HTTP header/body pattern matching, plugin architecture and naming/versioning, code refactoring for simplicity, and traceable commit history for future extensibility.

March 2025: Ostorlab/KEV delivered targeted CVE-2025-29927 detection to improve proactive security coverage for a critical Next.js bypass. A new Nuclei template was created and integrated into the agent group configuration, with README updated to reflect the capability. No major bugs fixed in this scope. Business value: faster detection, reduced exposure, and clearer guidance for operators. Skills demonstrated: Nuclei templating, agent configuration, documentation, and collaborative commits.

February 2025 (Ostorlab/oxo): Focused on improving type safety and test clarity without altering runtime behavior. Added type hints to an asynchronous test function and extended AgentPersistMixin.exists to accept bytes or string, enabling clearer code and safer data handling. Updated both the source and test files accordingly; groundwork laid for stronger static analysis and future refactors, with no user-facing feature changes.
