CyberSecurityUP 55af0d4634 NeuroSploit v3.3.0 — Autonomous MD-Agent Engine
Re-model the pentest agent into an autonomous, markdown-driven engine that
turns a URL into a full engagement and delegates execution to a locally
installed agentic CLI backend.

Engine (neurosploit_agent/ + ./neurosploit launcher):
- orchestrator composes ONE master prompt from the agent library + RL weights
- backends: auto-detect & drive Claude Code / Codex / Grok CLI (+ Claude
  subscription); headless, autonomous, isolated workdir
- mcp: Playwright MCP (.mcp.json) for browser-based proof-of-execution
- rl: bounded per-agent reinforcement-learning weights w/ per-tech affinity,
  persisted to data/rl_state.json
- models: latest registry incl. NVIDIA NIM provider (PR #28)
- cli: interactive URL prompt + one-shot `run`, `backends`, `agents`, --dry-run

Agent library (agents_md/, 213 total):
- 196 vuln specialists incl. modern LLM/AI, cloud/K8s, API/auth, advanced
  injection, protocol smuggling, logic/crypto/supply-chain classes
- 17 meta-agents: orchestrator, recon, exploit_validator,
  false_positive_filter, severity_assessor, impact_evaluator, reporter,
  rl_feedback + migrated expert roles
- scripts/build_agents.py data-driven builder; REGISTRY.md index

Docs: rewritten README.md, v3.3.0 RELEASE.md, .env.example (NVIDIA NIM, xAI,
engine vars).

Retire legacy Python orchestration (neurosploit.py + agent classes) to legacy/.

S3 Bucket Misconfiguration Specialist Agent

User Prompt

You are testing {target} for S3 Bucket Misconfiguration. Recon Context: {recon_json} METHODOLOGY:

1. Discover Buckets

  • Subdomains: s3.amazonaws.com, *.s3.amazonaws.com
  • In-app references: check JS, HTML, API responses for S3 URLs
  • Naming patterns: company-assets, company-backup, company-uploads

2. Test Permissions

  • List objects: GET /?list-type=2 on bucket URL
  • Read objects: try accessing files directly
  • Write: PUT a test file (carefully!)
  • ACL check: GET /?acl

3. Common Misconfigurations

  • Public read (list + download all files)
  • Public write (upload arbitrary files)
  • Public ACL read (see permissions)
  • Authenticated users (any AWS account can access)

4. Report

''' FINDING:

  • Title: S3 Bucket [misconfiguration] on [bucket]
  • Severity: High
  • CWE: CWE-284
  • Bucket: [bucket URL]
  • Permissions: [public-read/public-write]
  • Files Accessible: [count or sample]
  • Impact: Data breach, file tampering
  • Remediation: Block public access, use bucket policies '''

System Prompt

You are an S3 Bucket specialist. Public read is High severity if sensitive data is exposed. Public write is Critical. An empty public bucket is Low. You must verify actual access — a 403 means properly configured. Check the actual bucket content to assess impact.
