Perform a thorough security assessment based on the request below. Use the pentest-agent MCP tools — they execute real Docker-based security tools. **Request:** $ARGUMENTS **Every tool response includes a `next.required` field telling you what to call next.

Hundreds of tools: nikto, sqlmap, gobuster, hydra, testssl, enum4linux-ng, wapiti, searchsploit, etc. ### `http(action, url, method, headers, body, options)` - `action="request"` — send an HTTP request. options: `poc=false`, `burp_proxy=http://127.0.0.1:8080` - `action="save_poc"` — save a raw .http file to pocs/. options: `title=poc`, `notes=` ### `report(action, data)` - `action="finding"` — data: `{title, severity, target, description, evidence, tool_used, cve}` - `action="diagram"` — data: `{title, mermaid}` - `action="note"` — data: `{message}` - `action="coverage"` — data: `{type, ...}`: - `type="endpoint"` — `{path, method, params=[{name, type, value_hint}], discovered_by, auth_context}` - `type="tested"` — `{cell_id, status (tested_clean|vulnerable|not_applicable|skipped), notes, finding_id}` - `type="bulk_tested"` — `{updates=[{cell_id, status, notes, finding_id}]}` - `type="reset"` — clear the matrix ### `session(action, options)` - `action="start"` — options: `{target, depth, scope, out_of_scope, max_cost_usd, max_time_minutes, max_tool_calls, model_profile}` (model_profile: full|medium|small) - `action="complete"` — options: `{notes}` - `action="status"` — returns current scan state (tools run, findings count, cost, remaining calls) - `action="recovery"` — returns what to do next after context compaction - `action="start_kali"` / `action="stop_kali"` — Kali container lifecycle ## Depth presets | Depth | Includes | Default limits | |-------|----------|----------------| | `recon` | port scan + subdomains + HTTP probe only | $0.10 · 15 min · 10 calls | | `standard` | recon + nuclei vuln scan + dir fuzzing | $0.50 · 45 min · 25 calls | | `thorough` | standard + full Kali toolchain | unlimited cost · unlimited time · unlimited calls | ## Workflow **Before running any tool:** If the request does not explicitly specify a depth or limits, ask the user: > **Target:** `` > **Which scan depth?** > - `recon` — ports · subdomains · HTTP probe only *(~$0.10 · 15 min · 10 calls)* > - `standard` — recon + nuclei vuln scan + dir fuzzing *(~$0.50 · 45 min · 25 calls)* > - `thorough` — standard + full Kali toolchain *(unlimited)* > > Any custom limits? (e.g. `max_cost_usd=0.25`, `max_time_minutes=20`) > Any out-of-scope hosts? Wait for the answer, then call `session(action="start", options={...})` with those parameters. If the user already specified depth or limits in their request, skip the question and proceed directly. **IMPORTANT: Do NOT pass `max_cost_usd`, `max_time_minutes`, or `max_tool_calls` to `session(action="start", options={...})` unless the user explicitly specified custom limits.** The depth preset already has the right defaults. Passing your own lower values defeats the purpose of the preset — especially for `thorough` which needs the full budget to systematically test all endpoints. **Network / web target:** 0. Call `session(action="start", options={...})` with target, depth, and scope — this sets the hard limits 1. Call `report(action="dashboard", data={"port": 7777})` — gives you a live URL to watch findings roll in 2. Run `scan(tool="naabu", ...)` + `scan(tool="subfinder", ...)` in the same response (parallel) 3. Run `scan(tool="httpx", ...)` on discovered open ports — **include ALL non-standard HTTP ports** (not just 80/443) 3a. **Service fingerprinting** — for every HTTP service (including non-standard ports), understand what it is before scanning: - Try multiple HTTP methods (GET, POST, PUT) — some services only respond to specific methods - Read response headers, body, and error messages for application/version clues - **Check page content and SSL certificates for other hostnames** — if you find references to subdomains in page content, link URLs, or redirect targets, add them to `/etc/hosts` and investigate. For HTTPS services, inspect the SSL certificate's CN and SAN fields — they often reveal additional subdomains (e.g. `git.target.com`). Also try vhost enumeration by fuzzing the Host header - Use technology fingerprinting tools to identify the framework - If the service has a login page or management console (database consoles, admin panels, deployment UIs), try default and blank credentials before moving on — many management tools ship with well-known defaults or no password at all - **Understand how multiple applications on the same host interact** — if a ticketing system generates emails at the target domain, or a registration system requires domain-specific email verification, think about how one application's features can be used to satisfy another's requirements - Call `report(action="note", data={...})` with what each port is running and its version 3b. **DNS enumeration** — if port 53 (DNS) is open, attempt a zone transfer immediately — this is one of the fastest ways to discover hidden subdomains and vhosts that aren't publicly indexed: - Try zone transfer: `kali(command="dig axfr @TARGET DOMAIN")` - Any discovered subdomains: add to `/etc/hosts` and investigate each one as a separate attack surface - If zone transfer fails, try subdomain brute-force: `kali(command="dnsrecon -d DOMAIN -D /usr/share/seclists/Discovery/DNS/subdomains-top1million-5000.txt -t brt")` 3c. **Accessible file services** — if FTP, SMB, NFS, or similar file-sharing services are open: - Check for anonymous/null session access - List and download everything accessible — any file could contain credentials, internal documentation, network diagrams, endpoints, or configuration secrets - Read the contents of every downloaded file. For binary formats (PDFs, Office docs), extract the text so you can search it. For archives, extract and inspect contents. If an archive is password-protected, crack it — use the appropriate `*2john` tool (rar2john, zip2john, pdf2john, etc.) to extract the hash, then crack with john and the rockyou wordlist - If application source code is accessible (PHP, Ruby, Python, Java, Node.js), read it for vulnerabilities — SQL injection patterns, hardcoded credentials, insecure deserialization, route definitions, authentication logic, and file upload handling - Look for encoded data (base64, hex) in any file or API response — decode it - Check if any file service overlaps with a web application's source or deployment directory — if you can write files to where the application reads code or serves content, that's code injection or webshell upload 4. **Auth service checkpoint (early) — MANDATORY, DO NOT SKIP** — after port scanning and service detection, check if any **authentication-bearing services** were found: - SSH, FTP, SMB/CIFS, RDP, Telnet, VNC - HTTP with login form, Basic/Digest auth, or admin panel - Databases (MySQL, PostgreSQL, MSSQL, MongoDB, Redis) - LDAP, Kerberos, SNMP (community strings) **If ANY auth service is present (standard/thorough depth): you MUST chain into `/credential-audit`.** This is a hard gate — do not proceed to step 5 without invoking it. Do NOT attempt ad-hoc hydra/medusa/ncrack commands yourself — the credential-audit skill is systematic and covers cross-service spraying, username-derived passwords, and platform-aware enumeration that ad-hoc commands will miss. Choose depth based on available intelligence: - **No usernames known yet**: `depth=quick` — tests default creds + common usernames + top-100 passwords - **Usernames available** (from user context, prior scans, FTP files, web scraping, OSINT, etc.): `depth=standard` — includes username-derived password mutations + full common password lists ``` # READ THE FILE NOW and follow its workflow: cat ~/.config/opencode/commands/credential-audit.md # Then invoke with: # /credential-audit service=ssh,ftp depth=quick context='Auth services found: SSH on 2222. No user list yet.' # Usernames available from any source: cat ~/.config/opencode/commands/credential-audit.md # Then invoke with: # /credential-audit service=ssh depth=standard userlist=/tmp/discovered-users.txt context='5 usernames found via FTP anonymous access. Services: SSH on 2222.' ``` Resume the pentester workflow after credential-audit returns. **Username sources to check before invoking** — gather ALL available usernames from ANY source before calling credential-audit: - User-provided context in the scan request (e.g. "users anne, john found in prior scan") - FTP anonymous files (user lists, backup files, config files) - Web pages (team pages, about pages, comments, metadata) - OSINT (email addresses → username derivation) - SNMP enumeration results - SMB share contents - LDAP anonymous queries - Certificate CN/SAN fields - nmap script output (ssh-auth-methods, ftp-anon, smb-enum-users) - Prior scan data in findings.json for the same target Write all discovered usernames to `/tmp/discovered-users.txt` via `kali(command=...)` before invoking. 5. **Directory and file enumeration on ALL HTTP ports** — run directory enumeration with file extension fuzzing on every HTTP service. Include common sensitive file extensions — many targets have discoverable text files, backups, and configs that reveal credentials, usernames, changelogs, or version information: ``` scan(tool="ffuf", target="http://TARGET:80", options={"extensions": ".txt,.php,.bak,.old,.conf,.xml,.json,.env,.log,.sql,.zip"}) ``` If Basic Auth is required, use gobuster with credentials: `-U user -P pass`. If the first wordlist finds nothing, try a larger one. 5a. **Access control bypass** — for any endpoint returning 403, 401, or "restricted" responses, don't skip it. Test whether the restriction can be bypassed: - Add headers that make the server think the request comes from localhost: `X-Forwarded-For: 127.0.0.1`, `X-Real-IP: 127.0.0.1`, `X-Original-URL`, `X-Custom-IP-Authorization: 127.0.0.1` - Try different HTTP methods on the same endpoint (GET blocked → try POST, PUT, PATCH) - Try path variations: `/endpoint`, `/endpoint/`, `/endpoint/.`, `//endpoint`, `/endpoint%00` - Any bypassed endpoint is worth investigating further — it was restricted for a reason and may contain sensitive functionality 5b. **Parameter tampering** — when interacting with forms, APIs, or registration flows, inspect and manipulate request parameters (role fields, hidden fields, pricing, resource IDs). If you find injection points, chain into `/web-exploit` for deep exploitation. If you find business logic flaws (value/quantity manipulation, workflow bypass, authorization issues), chain into `/business-logic` 6. **Hotwire/Turbo detection before spidering** — before running the spider, probe the target for Hotwire/Turbo signals: ``` # Check homepage HTML and response headers for Turbo indicators http(action="request", method="GET", url="TARGET/") ``` Switch to `mode="playwright"` automatically if ANY of these signals are present: - Response HTML contains `` tags or JS bundle references) - Response headers include `Turbo-Frame:` or `Vary: Turbo-Frame` - `httpx` fingerprint shows Rails 7+ (`X-Runtime`, `Set-Cookie: _session_id` or similar) AND the app renders HTML (not JSON-only API) ``` # Fast mode (katana) — default for non-Turbo apps scan(tool="spider", target="TARGET", options={"depth": 3}) # Playwright mode — Hotwire/Turbo detected; also use when re-spidering with auth cookies scan(tool="spider", target="TARGET", options={ "mode": "playwright", "depth": 3, "cookies": {"_session_id": "SESSION_TOKEN_HERE"}, "max_pages": 200 }) ``` Run `scan(tool="spider", ...)` on confirmed web targets to map all reachable endpoints 6a. **Endpoint inventory + coverage matrix — MANDATORY for web targets.** After spider and ffuf complete, register every discovered endpoint into the coverage matrix. For each endpoint, identify all parameters (query params, form fields, JSON body keys, path segments with IDs) and their types/hints: ``` report(action="coverage", data={ "type": "endpoint", "path": "/profile/{id}", "method": "GET", "params": [{"name": "id", "type": "path", "value_hint": "integer"}], "discovered_by": "spider", "auth_context": "none" }) report(action="coverage", data={ "type": "endpoint", "path": "/api/users", "method": "GET", "params": [{"name": "q", "type": "query", "value_hint": ""}], "discovered_by": "spider", "auth_context": "jwt" }) report(action="coverage", data={ "type": "endpoint", "path": "/login", "method": "POST", "params": [ {"name": "username", "type": "body_form", "value_hint": ""}, {"name": "password", "type": "body_form", "value_hint": ""} ], "discovered_by": "spider", "auth_context": "none" }) ``` Param type values: `path`, `query`, `body_form`, `body_json`, `header`, `cookie` Value hint values: `integer`, `string`, or empty for default Register ALL endpoints — the matrix auto-generates injection test cells per applicability rules. Then chain into `/web-exploit` with the coverage context: ``` # READ THE FILE NOW and follow its workflow: cat ~/.config/opencode/commands/web-exploit.md # Then invoke with: # /web-exploit context='Coverage matrix built with N endpoints and M test cells. Auth uses JWT. App is Python/Flask.' ``` The web-exploit skill will systematically work through every pending cell in the matrix, ensuring no endpoint/param/injection combination is missed. **On thorough depth — also chain `/param-fuzz` and `/business-logic` after `/web-exploit` completes:** ``` cat ~/.config/opencode/commands/param-fuzz.md # Then invoke with: # /param-fuzz depth=thorough context=' endpoints registered. App is . Generated values observed: .' cat ~/.config/opencode/commands/business-logic.md # Then invoke with: # /business-logic depth=thorough context='.' ``` `/param-fuzz` covers: auth stripping, type confusion, boundary values, mass assignment, and entropy of generated values. `/business-logic` covers: value/quantity logic, workflow bypass, state machine abuse, BOLA/BFLA, replay/idempotency, quota bypass, and multi-tenant isolation. Both run after `/web-exploit` so injection findings are already confirmed and can inform where to focus. **Thorough-depth iteration gate — mandatory re-runs:** On `depth=thorough`, `session(action="complete")` enforces **3 full passes** before the scan can close. Each blocked call returns a **mandatory re-run brief** — concrete, ordered commands to re-execute all tools and skills at escalating aggressiveness. This is not a list of suggestions: you must execute every numbered step. - **Pass 1 brief** (after first complete() call): re-invoke /web-exploit (sqlmap --level=4 --risk=3, second-order injections, blind/OOB SQLi), /param-fuzz (bigger wordlists, HTTP verb tampering, type confusion), /business-logic (10 concurrent requests, all 9 phases again), /ai-redteam (PyRIT crescendo 10 turns, full Garak probe set), nuclei with all template categories, ffuf with raft-large-words.txt, and chain all unchained criticals to maximum impact. - **Pass 2 brief** (after second complete() call): re-invoke everything at MAXIMUM aggression — sqlmap --level=5 --risk=3 with tamper scripts, commix blind OS injection on all params, HTTP request smuggling, CRLF, web cache poisoning, deserialization probes on all cookies, 50-concurrent idempotency attacks, full sequential BOLA enumeration across all resource types, PyRIT 15-turn jailbreaks with hidden tool parameters. Produce a single executable end-to-end chain PoC for every critical finding. - **What "re-run" means**: reset tested_clean cells back to pending, use different techniques and payloads than pass 1, use more aggressive tool flags, test attack vectors that weren't tried before (not just the same tests again). - Call `session(action="recovery")` at any point to check `iteration_progress` (e.g. `"Iteration 2/3 — 1 more required"`). - Only after all quality gates AND 3 complete passes will `session(action="complete")` succeed. 6c. **Re-spider trigger** — the spider must re-run when the attack surface expands: 1. **New valid credentials discovered** — re-spider with auth cookie to discover authenticated-only endpoints 2. **Fuzzing reveals a new directory tree** — e.g., ffuf finds `/api/v2/` — spider that subtree 3. **Privilege escalation achieved** — re-spider as the higher-privilege user to find admin endpoints After re-spider, register all new endpoints into the coverage matrix. Existing cells are preserved — only genuinely new endpoints (deduplicated on normalized path + method) get added. The web-exploit skill then tests all new pending cells. 6b. **Source code checkpoint — MANDATORY when code is leaked** — if at ANY point during the scan you discover application source code (via path traversal, `.zip`/`.bak` file download, git repository exposure, directory listing, LFI, or any other means): - **STOP the current workflow phase** - Read and analyze the discovered source code immediately - Search for: hardcoded secrets, SQL query patterns, deserialization calls (`yaml.load`, `pickle.loads`, `eval`, `unserialize`), route definitions, authentication logic, file upload handlers, template rendering - Chain into `/codebase` if a substantial portion of the app source is available: ``` # READ THE FILE NOW and follow its workflow: cat ~/.config/opencode/commands/codebase.md # Then invoke with: # /codebase /tmp/leaked-source depth=quick context='Source code leaked via [method]. Partial codebase recovered.' ``` - Use discovered code patterns to inform ALL subsequent testing — if you find `yaml.load()` in source, immediately test YAML deserialization; if you find raw SQL queries, target those specific endpoints with SQLi; if you find `pickle.loads()`, test pickle deserialization - **Do NOT continue black-box testing when you have the source code for a specific feature** — switch to grey-box testing informed by the code - Resume the pentester workflow from where you left off 7. Call `report(action="diagram", data={...})` with a Mermaid diagram of the discovered network/app topology 8. Run `scan(tool="nuclei", ...)` on confirmed web services 9. **Exploit-DB lookup** — for every identified application + version (from httpx, whatweb, nuclei, or nmap service detection), search for known exploits: ``` kali(command="searchsploit saltstack 3000") kali(command="searchsploit apache 2.4.49") ``` If searchsploit returns relevant exploits: - **Has a Metasploit module?** → chain into `/metasploit`: ``` cat ~/.config/opencode/commands/metasploit.md ``` - **Standalone script only?** → mirror it, review, and run directly: ``` kali(command="searchsploit -m 48421") # download exploit to /tmp/ kali(command="cat /tmp/48421.py | head -30") # review what it does kali(command="python3 /tmp/48421.py --master TARGET") # run the exploit ``` - **Exploit needs a reverse shell callback?** → chain into `/reverse-shell`: ``` cat ~/.config/opencode/commands/reverse-shell.md ``` - **Needs deeper analysis?** → chain into `/analyze-cve`: ``` cat ~/.config/opencode/commands/analyze-cve.md ``` 9a. **Dependency version CVE lookup** — for every identified technology version (from httpx headers, error pages, `/static/` paths, or source code): - Check response headers for version strings: `Server`, `X-Powered-By`, `X-AspNet-Version`, `X-Generator` - Parse version from known paths: `/static/js/jquery-3.2.1.min.js`, `flask==0.10.1` in requirements.txt - For each versioned component, search for known CVEs: ``` kali(command="searchsploit flask 0.10") kali(command="searchsploit werkzeug 0.14") kali(command="searchsploit jinja2 2.5") kali(command="searchsploit pyyaml 3.13") ``` - Cross-reference with NVD/CVE databases for critical vulnerabilities in the identified stack - Check for known-vulnerable JavaScript libraries served by the application (jQuery, Angular, React, lodash) — use `retire.js` patterns or manual version checking - **Report each vulnerable dependency** with CVE ID, affected version, and known exploit availability — even if you cannot prove exploitability from a black-box perspective, these are valid findings (severity: Medium for exploitable, Low for theoretical) 10. Use `kali(command=...)` for deep dives (only in `standard` / `thorough`): nikto, sqlmap, gobuster, testssl, etc. 10a. **Post-exploitation checkpoint — MANDATORY on any foothold** — a foothold is either of these two things: **(A) Command execution achieved** — via command injection, SSTI, deserialization, file upload, debugger console, or any other vector. **(B) Credential material obtained** that authenticates to a reachable internal service — this means any form of secret that opens a door into a system not directly exposed: database passwords, private keys, API tokens, session material, service account credentials, cloud provider keys, internal service secrets extracted via SSRF, config leaks, or path traversal. The specific form does not matter. If you found something that lets you authenticate to something, that is a foothold. **Do NOT log credential material as a finding and continue to the next coverage cell.** Both (A) and (B) require the steps below — the difference is only the `access=` argument passed to `/post-exploit`. **For credential material (B):** skip Step 1 (no shell needed yet) and go directly to Step 2 using the service the credentials target as the pivot point. **Step 1 — Establish stable access:** - If the RCE is blind (no direct output, e.g. blind command injection), chain into `/reverse-shell` to get an interactive shell from the target to the Kali container. This transforms blind RCE into a full shell and makes all subsequent post-exploitation dramatically more efficient: ``` cat ~/.config/opencode/commands/reverse-shell.md ``` - If the RCE already provides interactive output (e.g. Werkzeug debugger console, web shell), proceed directly. **Step 2 — Environment detection and internal network discovery** — run these commands on the target to classify the environment and map reachable networks: ``` # Detect containerization cat /proc/1/cgroup 2>/dev/null | grep -E 'docker|kubepods|containerd' ls -la /.dockerenv 2>/dev/null # Detect Kubernetes ls /var/run/secrets/kubernetes.io/serviceaccount/ 2>/dev/null env | grep KUBERNETES # Detect cloud curl -s --max-time 2 http://169.254.169.254/latest/meta-data/ 2>/dev/null curl -s --max-time 2 -H "Metadata-Flavor: Google" http://169.254.169.254/computeMetadata/v1/ 2>/dev/null # Detect Active Directory / domain-joined host cat /etc/krb5.conf 2>/dev/null; echo "$USERDOMAIN $LOGONSERVER" 2>/dev/null ``` **Step 2b — Internal network scan (MANDATORY)** — always run this after environment detection. The goal is to discover what the compromised host can reach — this determines whether to chain into `/network-assess`, `/lateral-movement`, or `/ad-assessment`: ``` # Map network interfaces and subnets ip addr 2>/dev/null || ifconfig 2>/dev/null ip route 2>/dev/null || route -n 2>/dev/null || netstat -rn 2>/dev/null cat /etc/resolv.conf 2>/dev/null # Discover live hosts on local subnets (fast ARP-based or ping sweep) # Use the subnet from ip addr output, e.g. 10.0.0.0/24 for subnet in $(ip route 2>/dev/null | grep -v default | awk '{print $1}' | head -5); do echo "=== Scanning $subnet ===" for i in $(seq 1 254); do ip="${subnet%.*}.$i" ping -c1 -W1 "$ip" &>/dev/null && echo "LIVE: $ip" & done 2>/dev/null wait done # Active connections — reveals internal services the host talks to ss -tunapl 2>/dev/null || netstat -tunapl 2>/dev/null # ARP cache — hosts already communicated with ip neigh 2>/dev/null || arp -a 2>/dev/null # DNS zone info — may reveal internal hostnames cat /etc/hosts 2>/dev/null ``` If any scanning tools are available on the compromised host (nmap, ncat, curl), use them for more thorough service discovery on discovered subnets: ``` # Quick port scan on discovered live hosts (top ports) nmap -sT -T4 --top-ports 20 /24 2>/dev/null # Or if no nmap, use bash TCP scan for key ports for port in 22 80 443 445 3306 5432 6379 8080 8443 27017; do (echo >/dev/tcp//$port) 2>/dev/null && echo "OPEN: :$port" done ``` Record all discovered hosts, subnets, and services in a `report_note` — this feeds into the chaining decision in Step 3. **Step 3 — Chain into post-exploitation skills based on environment:** | Environment detected | Chain to | Depth | |---------------------|----------|-------| | Any RCE | `/post-exploit` | Always — privesc, credential harvesting, pivot prep | | Kubernetes (SA token, kubepods cgroup, KUBERNETES env vars) | `/container-k8s-security` | K8s RBAC abuse, secret enumeration, namespace traversal, container escape | | Docker (/.dockerenv, docker cgroup) without K8s | `/container-k8s-security` | Container escape, socket exposure, capability abuse | | Cloud metadata accessible (169.254.169.254) | `/cloud-security` | IMDS exploitation, IAM credential theft, cloud pivoting | | Internal network reachable (step 2b found live hosts on non-public subnets) | `/network-assess` | Internal service discovery, VLAN hopping, broadcast protocol abuse, lateral movement prep | | Credentials discovered during post-exploit | `/credential-audit` | Spray discovered creds across all known services | | Domain-joined host (AD indicators) | `/ad-assessment` | Domain enumeration, attack path analysis | ``` # Example chains — read each file and follow its workflow: cat ~/.config/opencode/commands/post-exploit.md # /post-exploit access=command_injection user=app os=linux context='Blind CMDi via POST /home size param. Alpine 3.7 container in K8s.' cat ~/.config/opencode/commands/container-k8s-security.md # /container-k8s-security perspective=internal context='RCE in pod cmd-5644658694. SA token at default path. K8s API at 10.96.0.1:443. Namespace: 141054a6-...' cat ~/.config/opencode/commands/network-assess.md # /network-assess perspective=internal context='RCE on 10.0.1.5. Step 2b found live hosts on 10.0.1.0/24 (10.0.1.1 gateway, 10.0.1.10 ssh, 10.0.1.20 http). ARP cache shows 10.0.2.0/24 also reachable.' ``` **This is a hard gate** — do NOT skip post-exploitation when a foothold is confirmed. A foothold is not the objective — it is the entry point. The real impact comes from what is reachable from it: internal networks, other services, cloud metadata, lateral movement paths. Skipping post-exploitation means reporting "credentials found" when the actual finding is "full database dump + RCE via PostgreSQL" or "JWT secret found" when the actual finding is "arbitrary admin token forgery for all users". **Blind RCE pivoting technique** — when you only have blind command injection (no reverse shell possible due to egress filtering), use the exfiltration pattern: ``` # Write command output to web-accessible directory POST /vulnerable-endpoint body: param=$(command > static/output.txt) GET /static/output.txt # read the output # For commands with special characters, base64 encode: POST /vulnerable-endpoint body: param=$(command | base64 > static/b64out.txt) GET /static/b64out.txt # decode locally ``` This is slower than an interactive shell but works when egress is blocked. Use it for initial enumeration, then try to find an egress channel for a reverse shell. 11. **Credential material checkpoint (late) — MANDATORY if new material found** — after deep enumeration, check if ANY new credential material was discovered since the early checkpoint: - A user list or username file (e.g. from FTP anonymous access, directory listing, web scraping, config files) - Password hashes (e.g. from database dumps, `.htpasswd`, LDAP, SAM/NTDS) - Cleartext credentials or API keys (e.g. from config files, backup files, git history) - Additional usernames from any source not available at step 4 **If new credential material was found: chain into `/credential-audit` again with `depth=thorough` and the discovered material.** ``` # READ THE FILE NOW and follow its workflow: cat ~/.config/opencode/commands/credential-audit.md # Then invoke with: # /credential-audit service=ssh,ftp,http depth=thorough userlist=/tmp/discovered-users.txt context='5 usernames found in users.txt.bk via FTP anonymous access. Services: SSH on 22, FTP on 21, HTTP on 80.' ``` Before invoking, write the discovered usernames to `/tmp/discovered-users.txt` via `kali(command=...)`. The credential-audit skill will handle: username-derived passwords, lockout detection, intelligent wordlist generation (cewl + john mutations + mask attacks), cross-service spraying, and verification. **Do NOT run ad-hoc hydra/medusa commands yourself** — the dedicated skill is more thorough and systematic. **If NO new material was found but the early checkpoint (step 4) was run at `depth=quick`**: consider upgrading to `depth=standard` now that more context is available (e.g. OS version, service banners, application type). 12. Use `http(action="request", ...)` to manually verify or PoC any finding 13. **Always before `session(action="complete", options={...})`:** - Call `report(action="diagram", data={...})` with a Mermaid diagram of the **application architecture** — even for pure web targets with no network infrastructure. Map out every component, endpoint, and feature that was tested (login, API routes, file upload, admin panel, auth flows, third-party integrations, etc.). This gives a clear picture of the attack surface covered. - For every confirmed exploit, call `http(action="request", options={"poc": true})` **and** `http(action="save_poc", ...)` to produce a Burp-ready `.http` file. Do not skip this even if the finding was already logged via `report(action="finding", data={...})`. - **On `depth=thorough`**: `session(action="complete")` enforces 3 mandatory re-run passes (see step 6c). When blocked, the response is a numbered list of concrete re-run commands — execute ALL of them, then call complete again. Do not skip steps or paraphrase them as done without running the tools. Check `session(action="recovery")` → `iteration_progress` to track your pass count. 14. Call `session(action="complete", options={...})` with a summary when done or when a limit is hit **Local codebase:** 0. **Chain into `/codebase` first** — this performs a comprehensive white-box source code review (ASVS 5.0), maps all endpoints, identifies auth architecture, traces dangerous patterns, and produces a security profile that makes subsequent scanning far more targeted: ``` # READ THE FILE NOW and follow its workflow: cat ~/.config/opencode/commands/codebase.md # Then invoke with: # /codebase /path/to/code depth=standard ``` 1. After `/codebase` completes, invoke additional skills based on what was found — do NOT test manually: - **Web/API endpoints present AND live target available** → MUST invoke `/web-exploit`: - First register all code-discovered endpoints into the coverage matrix (use `report(action="coverage", data={type:"endpoint",...})` for each one) - Then invoke `/web-exploit` with context from the code review (stack, auth type, known injection points): ``` cat ~/.config/opencode/commands/web-exploit.md ``` - **AI/LLM code found** (OpenAI calls, prompt templates, LangChain, chat endpoints, function calling) → MUST invoke `/ai-redteam`: ``` cat ~/.config/opencode/commands/ai-redteam.md ``` - **HTTPS target** → invoke `/ssl-tls-audit`: ``` cat ~/.config/opencode/commands/ssl-tls-audit.md ``` - You are now in grey-box mode: the coverage matrix has code-discovered endpoints and parameters, not just spider-discovered ones 2. If no live target is available, skip to step 3 3. Call `session(action="complete", options={...})` when done ## Chaining other skills During a pentest you may invoke other skills when the situation calls for it: | Skill | When to invoke | |-------|----------------| | `/codebase` | **Local codebase target — always chain first.** White-box ASVS 5.0 review: maps endpoints, auth, dangerous patterns, IaC. Produces security profile that makes all subsequent scanning targeted | | `/osint` | Before active scanning — run passive recon first to map subdomains, emails, employees, tech stack, cloud storage, and leaked credentials | | `/analyze-cve` | You discover a CVE-affected dependency (e.g. via nuclei or semgrep) — invoke it to trace whether the vulnerable code path is actually reachable and generate a Burp PoC | | `/web-exploit` | **MANDATORY after step 6a — web targets.** After spider + ffuf complete, build full endpoint inventory and chain here for systematic testing of EVERY endpoint against EVERY vulnerability class. Also invoke **immediately at detection time** — not after failing — when ANY of these are present: (1) non-Jinja2 template engine in stack (Twig, ERB, Smarty, Freemarker, Pebble, Velocity, Mako) — payloads differ per engine, using Jinja2 syntax on Twig produces zero output; (2) serialization format in cookie or request body (YAML `!!python`, PHP `O:`, Java `rO0AB`, Python pickle `\x80\x04`) — gadget chains are framework-specific; (3) blind injection confirmed (SQLi, CMDi, SSTI with no reflection) — switch to automated tooling immediately, manual char-by-char extraction wastes the entire budget; (4) XXE parse accepted — read all extraction variants before concluding entities are filtered; (5) 401/403 on a target endpoint — read auth bypass section (HTTP method tampering, path normalization, header spoofing) BEFORE defaulting to credential brute-force | | `/api-security` | **MANDATORY when an API surface is discovered** — OpenAPI/Swagger spec found (`/swagger.json`, `/openapi.json`, `/v3/api-docs`), GraphQL endpoint (`/graphql`, `/graphiql`, `/playground`), gRPC reflection responding, SOAP WSDL, MCP server, or any `/api/v*/...` route returning structured JSON. Chain here for the OWASP API Top 10 (2023): BOLA, BFLA, mass assignment, JWT/OAuth abuse, business-flow abuse, and inventory drift. Run BEFORE `/web-exploit` for API-first targets — `/web-exploit` handles injection depth, `/api-security` handles the auth/authz/business-logic surface that web-exploit doesn't cover | | `/codebase` | **Source code discovered mid-pentest** — via path traversal, .zip download, git exposure, or any other means. Chain immediately to analyze leaked code and convert to grey-box testing. This dramatically improves coverage. | | `/metasploit` | Exploitable CVE confirmed by nuclei/nikto — validate and exploit with Metasploit modules (runs in separate Docker container) | | `/ssl-tls-audit` | TLS services found — deep TLS/SSL configuration audit with PCI DSS 4.0 and NIST 800-52r2 compliance mapping | | `/network-assess` | Internal network scope — VLAN segmentation, broadcast protocol abuse (LLMNR/NBT-NS), SNMP/NFS/SMB enumeration, router/switch audit. Also chain from step 10a when internal subnets are reachable from a compromised host | | `/credential-audit` | **MANDATORY — three triggers:** (1) **Auth services detected** during recon (SSH, FTP, SMB, RDP, HTTP login, database, etc.) — invoke with `depth=quick` (no usernames) or `depth=standard` (usernames available). This is a hard gate at step 4 — do NOT skip. (2) **New credential material discovered** later (user list, hashes, cleartext creds from FTP anonymous, config leak, web scrape, LDAP dump, etc.) — invoke again with `depth=thorough`, the discovered user list, and all auth services. **NEVER run ad-hoc hydra/medusa yourself — always chain here.** (3) **JWT token found in any cookie or Authorization header** — invoke immediately for the full JWT attack sequence: `alg:none` bypass, RS256→HS256 key confusion, kid he …(truncated)
