hunt-vpn

hunt-vpn is a skill for Claude Code, Codex from Encod3d-Sec/TORCH. It costs 48 tokens per session (2,322 once invoked), scanned A, original, MIT.

A workflow for assessing enterprise SSL VPN appliances, which are network devices that provide encrypted remote access to an organisation.

In plain words
What is it for?
Use it when recon reveals products from vendors such as Fortinet, Citrix, Cisco, Palo Alto, or Ivanti. It helps build a vulnerability matrix and select documented checks for the identified appliance.
Why use it?
It organises vendor identification and checks for known weaknesses, exposed credentials, and vulnerable pre-login interfaces before deeper testing.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hunt-vpn scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Hunt: Enterprise VPN Appliances

Assumes hunt-core for the scope gate, two-account rule, confirmation gate, enumeration limits, stop conditions, wiki protocol, FIND output, and Deadends. Do not re-derive any of that here.

Wiki

qmd_query "SSL VPN Fortinet Citrix Cisco Palo Alto Pulse Ivanti CVE default credentials pre-auth exploit" via wiki-search MCP

Hub: [[network-moc]] (live index). Primary page: [[network-service-attacks]] (VPN-protocol section: IKE aggressive-mode PSK capture, PPTP handshake capture). CVE arsenal: wiki/cheatsheets/cve-arsenal.md (Perimeter / VPN / edge - Fortinet/Citrix/Ivanti/PAN-OS/Cisco pre-auth CVEs with PoC). Default creds: wiki/cheatsheets/default-credentials.md. Anchors: [[network-discovery]] (locating and banner-fingerprinting the exposed appliance).

When to Use

Recon surfaces: +CSCOE+ paths (Cisco ASA), Set-Cookie: SVPNCOOKIE= (Fortinet), NSC_AAA= (Citrix), DSAuthSession= (Pulse), BIGipServer* (F5), ports 443/8443/10443 with VPN login pages.

Attack surface (ranked)

Work top-down; exploit the first rung that lands, do not jump to CVEs before fingerprinting.

  1. Vendor fingerprint (cookie / header / login-page path) - which appliance, then which page below.
  2. Version fingerprint (JS file paths, meta tags, build strings) - narrows the CVE matrix to what actually applies to this build.
  3. Default credentials (short known-list, non-disruptive) - cheapest full-admin win, try before CVEs.
  4. Pre-auth CVE for the fingerprinted vendor + version - file read, session-token leak, or RCE.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

hunt-vpn is a skill published in the GitHub repository Encod3d-Sec/TORCH (318 stars, last pushed 8d ago), licensed MIT. It adds 48 tokens to every session and 2,322 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
