CyberStrike: The Open-Source AI Agent Turning ChatGPT Into an Autonomous Pentester

CyberStrike: The Open-Source AI Agent Turning ChatGPT Into an Autonomous Pentester 🔓🤖

If you're into cybersecurity, AI agents, or open-source dev tools, this one's worth a look.

CyberStrike is an open-source, AI-augmented offensive security harness released in July 2026. Instead of piping scan output into a chatbot for a summary, it wraps your existing ChatGPT, Claude, or other LLM subscription in a full "intelligence layer" — injecting OWASP methodology, attack-chain reasoning, and tool orchestration logic so the model behaves like a specialized red-team operator.

🧠 Architecture highlights:

• 13+ domain-specific agents — Web (OWASP WSTG), Mobile (MASTG/MASVS), Cloud (CIS benchmarks), Internal Network (AD attacks, lateral movement)
• 7,600+ Ed25519-signed security skill files covering JWT abuse, SSRF, SSTI, GraphQL exploitation, and post-exploitation playbooks for AWS, Azure, Kubernetes
• Supports 150+ AI providers and ~5,300 models — including fully offline runtimes like Ollama and LM Studio for air-gapped environments
• HackBrowser — a built-in Chromium browser that captures live traffic and runs 8 parallel proxy sub-testers with a three-gate confirmation protocol to cut false positives
• Bolt — lets tooling run on remote servers via Ed25519 key pairing, coordinating multiple attack surfaces from one terminal
• Integrates with an MCP ecosystem exposing 176 additional tools for cloud auditing, GitHub security posture, CVE intel, and OSINT

⚙️ Install:

npm i -g @cyberstrike-io/cyberstrike@latest && cyberstrike

Also available via Homebrew, Scoop, or a curl script. AGPL-3.0 licensed, cross-platform (macOS/Windows/Linux).

⚠️ Important distinction: Don't confuse CyberStrike with CyberStrikeAI — a separate, Go-based tool linked by researchers to real-world attacks on Fortinet FortiGate appliances, tied to a suspected nation-state actor. Same-sounding name, completely different project and intent.

For defenders, the deeper takeaway is that autonomous AI-driven recon leaves a distinct network fingerprint — chained contextual requests, near-zero timing variance, and outbound calls to LLM provider APIs from hosts with no legitimate reason to make them.

Anyone here building on top of CyberStrike, MCP-based security tooling, or similar AI pentesting agents? Would love to compare notes in the comments.
