Research update for HackTricks content

🤖 Agent Actions

I’ve read the existing SIP page and the related VoIP content and updated the SIP page to add practical, protocol-focused security content without duplicating the broader attacks that already exist in the main VoIP page.

What I changed and added

• Fixed small inaccuracies/typos in the INVITE/SDP example (corrected a=rtpmap line) and REGISTER section (formatting and “Authorization” spelling).
• Added “SIP Security and Pentesting Notes” section with:
  • Fingerprinting and discovery using OPTIONS (including a raw netcat probe and an nmap example).
  • Enumeration behavior notes and hardening tip for Asterisk (alwaysauthreject for chan_sip; notes for PJSIP).
  • Modern digest algorithms note (MD5, MD5-sess, SHA-256, SHA-512/256 per RFC 8760) and an actionable offline-cracking example using hashcat mode 11400 with the expected hash format and command. citeturn0search10turn0search7
  • SIP over TLS (sips) and SIP over WebSockets (RFC 7118) quick notes and what to test. citeturn0search8
  • DoS quick checks with a concrete iptables hashlimit rate-limiting example for UDP/5060.
  • “Recent, relevant CVE” note on Asterisk PJSIP CVE‑2024‑35190 with fixed versions to watch for during assessments. citeturn0search3
  • Focused hardening checklist (TLS/SRTP, digest algo policy, Asterisk-specific flags, topology hiding, disable unused methods/rate limits).
• Cross-linked to the main VoIP page to avoid duplicating enumeration/attacks already covered there using the HackTricks internal reference block.
• Added a concise References section (kept to 2 items as requested).

Files modified

• src/network-services-pentesting/pentesting-voip/basic-voip-protocols/sip-session-initiation-protocol.md

Key sources used

• RFC 8760 (digest with SHA-256/SHA-512/256). citeturn0search7
• Asterisk GHSA advisory for CVE‑2024‑35190. citeturn0search3
• Hashcat wiki (mode 11400 SIP digest auth, MD5). citeturn0search9
• RFC 7118 (SIP over WebSocket). citeturn0search8

If you want me to also add a short subsection showing how to craft/modify SIP over WebSocket probes or to include an NSE example for sip-enum-users/sip-brute, I can extend the page further while keeping it non-duplicative.
