Written for no agent in particular: nothing here depends on one.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is -H 'Cookie: SESSID=../../../var/log/pan/test_$(id)_test.txt' \.

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

enterprise-vpn-attack 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 8d 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.

When to use this skill

Trigger when recon surfaces:

  • *.<client>.example/+CSCOE+/logon.html or similar +CSCOE+ paths → Cisco ASA / AnyConnect
  • intranet.* / vpn.* / connect.* / webvpn.* / wc.* / remote.* subdomains
  • Port 443 returning login pages with Server: Apache or banner like "AnyConnect", "FortiGate", "NetScaler", "GlobalProtect", "Pulse", "Ivanti"
  • TCP 8443 / 4443 / 10443 / 8888 (common VPN web-mgmt ports)
  • HTTP responses with Set-Cookie: webvpn= (Cisco) / SVPNCOOKIE= (Fortinet) / NSC_AAA= (Citrix) / DSAuthSession= (Pulse) / BIGipServer* (F5)

DO NOT use for:

  • Internal lateral-movement post-foothold (out of scope per user's boundary)
  • VPN client-side bugs (different attack class)
  • IPsec / L2TP / OpenVPN (different protocols, not SSL VPN web stack)

Vendor identification (fingerprinting)

Cisco ASA / AnyConnect

curl -skI 'https://target/+CSCOE+/logon.html' | head -10
# Look for: Set-Cookie: webvpn=; X-Frame-Options: SAMEORIGIN; CSP: ... block-all-mixed-content

ASA version: not banner-disclosed in modern builds; need to derive from JS file paths or test specific paths.

# Path-based version hints (older builds leaked builds in URLs)

# Look for: Set-Cookie: SVPNCOOKIE=, Server header missing or "xxxxxxxx-xxxxx"
