⚠️ AUTHORIZED USE ONLY This skill is for educational purposes or authorized security assessments only. You must have explicit, written permission from the system owner before using this tool. Misuse of this tool is illegal and strictly prohibited.

Mandatory confirmation gate Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:

1. Ask the user to state the exact target URL, IP, account, or resource.
2. Ask the user to confirm written authorization and the permitted scope.
3. Show the exact command(s) and explain their expected effect.
4. Wait for explicit confirmation in the current conversation.

Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.

HUNT-TLS-NETWORK — TLS/SSL & DNS Security

Reality Check (Read First)

Most findings in this class are Info/Low and routinely rejected as "best-practice" / "missing-hardening" by triage. This skill exists to stop you wasting a submission. Two questions before you report anything here:

1. Is there a real victim and a real action? "Missing HSTS" is not a vulnerability — demonstrated session-cookie capture from a victim you MitM'd is. "Missing CAA" is never a vulnerability you can demonstrate.
2. Does the program accept it? Many programs explicitly list missing SPF/DMARC, missing security headers, weak ciphers without exploit, and CAA as out of scope. Read scope first; quote the in-scope line in your report.

What actually pays in this class (in order):

• Dangling-CNAME / dangling-A subdomain takeover — you control content on target.com subdomain. Real impact, real bounty. (Owned in depth by hunt-subdomain; covered here for the TLS/DNS recon angle.)
• Spoofable DMARC, proven by delivered-to-inbox email — not "p=none exists" but an actual mail from ceo@target.com landing in a real inbox with a passing/none DMARC verdict in the headers.
• DNS AXFR returning internal hosts — full internal hostname/IP map. Concrete recon value, often Medium.
• mTLS / client-cert bypass on an internal service — reaching authenticated-only functionality without the cert. Real auth bypass = High.
• Exploited TLS weakness with a working decrypt/MitM PoC — almost never achievable remotely in 2024-2026 against a patched stack; see Phase 1 caveats.

What does NOT pay (do not report standalone): missing CAA, missing HSTS with no MitM PoC, missing security headers alone, weak-cipher support without an exploit, self-signed cert on a non-prod host, TLS 1.0/1.1 enabled without a downgrade victim.

Phase 1 — TLS/SSL Audit

# Quick TLS test with testssl.sh
brew install testssl
testssl.sh --fast $TARGET 2>/dev/null | grep -E "CRITICAL|HIGH|MEDIUM|OK|NOT" | head -30

# Or use sslyze (Python)
pip3 install sslyze
python3 -m sslyze $TARGET --json_out /tmp/sslyze_$TARGET.json 2>/dev/null
cat /tmp/sslyze_$TARGET.json | python3 -m json.tool | grep -i "vulnerability\|insecure\|error" | head -20

# Check certificate expiry and chain
echo | openssl s_client -connect $TARGET:443 -servername $TARGET 2>/dev/null | \
  openssl x509 -noout -dates -subject -issuer 2>/dev/null

# Check for weak ciphers manually (a successful handshake = the cipher is OFFERED, not exploitable)
openssl s_client -connect $TARGET:443 -cipher RC4-SHA 2>/dev/null | grep -i "cipher\|handshake"
openssl s_client -connect $TARGET:443 -cipher DES-CBC3-SHA 2>/dev/null | grep -i "cipher\|handshake"

# Protocol downgrade surface — TLS 1.0/1.1 still negotiable?
openssl s_client -connect $TARGET:443 -tls1   2>/dev/null | grep -E "Protocol|Cipher"
openssl s_client -connect $TARGET:443 -tls1_1 2>/dev/null | grep -E "Protocol|Cipher"

Accuracy / triage notes — do not over-claim TLS bugs:

• Offered ≠ exploitable. testssl/sslyze flagging RC4, 3DES, or TLS 1.0 means the server negotiates it. That is a hardening finding, not a demonstrated decrypt. Without a PoC it is Info/Low and frequently OOS.
• SWEET32 (CVE-2016-2183) — 3DES birthday attack. Requires a long-lived TLS session, an on-path attacker, and ~hundreds of GB / hours of same-key traffic. Realistically un-demonstrable in a bug bounty; report only the support of 3DES, expect Low/Info.
