CyberStrikeus/CyberStrike

CyberStrike is an open-source AI-powered offensive security harness that automates penetration testing through autonomous agents.

The tool addresses the challenge of conducting comprehensive security assessments by leveraging large language models to orchestrate attack workflows. It works by connecting to LLM providers—supporting Claude, GPT, and other models across multiple providers—and deploying specialized agents that execute security testing tasks. The system includes 13 specialized agents, 7,600 security skills, and 120 OWASP test cases that guide the AI in identifying vulnerabilities. It provides 56 built-in tools and integrates with 176 MCP tools for extended functionality, allowing the AI to interact with various security utilities and services.

Teams conducting penetration testing, bug bounty hunting, red team exercises, or security audits should consider this tool if they want to automate reconnaissance and exploitation workflows. It suits organizations that already use LLM subscriptions and want to repurpose those investments for security testing. The tool offers both terminal-based operation and a web UI for remote access, plus a Bolt feature for remote tool execution. It includes post-exploitation capabilities and supports 150+ AI providers with 5,300+ available models, giving flexibility in choosing which LLM to power the testing.

The project maintains active development with a published build workflow and a community presence on Discord. Documentation is available through a dedicated docs site alongside the main project website. The codebase is written in TypeScript and distributed through npm, making it accessible to developers familiar with JavaScript ecosystems.
