yaklang/websocket-security

WebSocket 핸드셰이크, CSWSH, 도구(wsrepl, ws-harness, Burp) 및 일반적인 취약점. 앱에서 실시간 채널, 채팅, 알림 또는 WS 기반 API를 사용할 때 활용하세요.

websocket-security란 무엇인가요?

이 스킬은 WebSocket 보안 취약점을 식별하고 테스트하는 데 중점을 둡니다. WebSocket 핸드셰이크 프로세스, CSWSH(Cross-Site WebSocket Hijacking) 공격, 그리고 wsrepl, ws-harness, Burp Suite와 같은 도구를 활용한 분석 방법을 다룹니다. 실시간 채널, 채팅, 알림, 또는 WebSocket 기반 API를 사용하는 애플리케이션에서 발생할 수 있는 일반적인 보안 결함을 이해하고, 이를 효과적으로 진단하고 대응할 수 있도록 지원합니다. 주로 보안 연구원, 침투 테스터, 그리고 WebSocket을 사용하는 개발자에게 유용하며, Yaklang 언어 기반의 스크립트를 통해 자동화된 테스트를 수행할 수 있습니다.

websocket-security은(는) 무엇을 하나요?

WebSocket 핸드셰이크, CSWSH, 도구(wsrepl, ws-harness, Burp) 및 일반적인 취약점. 앱에서 실시간 채널, 채팅, 알림 또는 WS 기반 API를 사용할 때 활용하세요.

개요

이 스킬은 WebSocket 보안 취약점을 진단하고 대응하는 방법을 제공합니다. WebSocket 핸드셰이크의 보안 메커니즘, CSWSH(Cross-Site WebSocket Hijacking) 공격의 원리, 그리고 주요 도구(wsrepl, ws-harness, Burp Suite)를 사용한 실전 분석 기법을 다룹니다.

주요 내용

  • WebSocket 핸드셰이크 보안: 핸드셰이크 과정에서의 인증, 권한 부여, CSRF 방어 등.
  • CSWSH (Cross-Site WebSocket Hijacking): 취약점 식별 및 악용 예시.
  • 도구 사용법:
    • wsrepl: 대화형 WebSocket 재생 도구.
    • ws-harness: WebSocket 연결을 위한 테스트 자동화 도구.
    • Burp Suite: WebSocket 트래픽 분석 및 변조.

사용 시나리오

  • 채팅 애플리케이션의 WebSocket 엔드포인트 보안 검사.
  • 실시간 알림 시스템의 CSWSH 취약점 점검.
  • WebSocket 기반 API의 인증 우회 가능성 평가.

yaklang/401-403-bypass-techniques

401/403 bypass playbook. Use when encountering access-denied responses on admin panels, API endpoints, or restricted paths. Covers path manipulation, HTTP method tampering, header injection, protocol downgrade, and automated bypass tools.

yaklang/active-directory-acl-abuse

Active Directory ACL abuse playbook. Use when exploiting misconfigured AD permissions including GenericAll, WriteDACL, DCSync rights, shadow credentials, LAPS reading, GPO abuse, and BloodHound-guided attack paths.

yaklang/active-directory-certificate-services

AD Certificate Services attack playbook. Use when targeting misconfigured AD CS for privilege escalation via ESC1-ESC13 template abuse, NTLM relay to enrollment, CA officer abuse, and certificate-based persistence.

yaklang/active-directory-kerberos-attacks

Kerberos attack playbook for Active Directory. Use when targeting AD authentication via AS-REP roasting, Kerberoasting, golden/silver/diamond tickets, delegation abuse, or pass-the-ticket attacks.

yaklang/ai-ml-security

AI/ML security playbook. Use when assessing model supply chain attacks (pickle RCE, poisoned weights), adversarial examples, model poisoning, model stealing, data privacy attacks (membership inference, model inversion), and autonomous agent security risks.

yaklang/android-pentesting-tricks

Android pentesting playbook. Use when testing Android applications for SSL pinning bypass, exported component abuse, WebView vulnerabilities, intent redirection, root detection bypass, tapjacking, and backup extraction during authorized mobile security assessments.

yaklang/anti-debugging-techniques

Anti-debugging detection and bypass playbook. Use when reversing protected binaries that detect debuggers via ptrace, PEB flags, timing checks, or signal/exception handlers on Linux and Windows.

yaklang/api-auth-and-jwt-abuse

API authentication and JWT abuse playbook. Use when testing bearer tokens, API keys, claim trust, header spoofing, rate limits, and API auth boundary weaknesses.

yaklang/api-authorization-and-bola

API authorization and BOLA testing playbook. Use when APIs expose object identifiers, nested resources, hidden writable fields, or weak function-level authorization.

yaklang/api-recon-and-docs

API reconnaissance and documentation review playbook. Use when discovering endpoints, schemas, versions, OpenAPI specs, hidden docs, and surface area for API testing.

yaklang/api-sec

Entry P1 category router for API security. Use when choosing between API recon, authorization, token abuse, and hidden-parameter workflows before any deeper API topic skill.

yaklang/arbitrary-write-to-rce

Arbitrary write to RCE playbook. Use when you have an arbitrary write primitive (from heap exploitation, format string, or OOB write) and need to convert it into code execution by targeting GOT, hooks, _IO_FILE vtable, exit_funcs, TLS_dtor_list, modprobe_path, .fini_array, or C++ vtables.

yaklang/authbypass-authentication-flaws

Authentication bypass testing playbook. Use when assessing login flows, password reset logic, account recovery, MFA bypass, token predictability, brute-force resistance, and session boundary flaws.

yaklang/auth-sec

Entry P1 category router for authentication and authorization. Use when testing login flows, sessions, object authorization, JWT, OAuth, CORS, CSRF, and enterprise SSO weaknesses before any deeper auth topic skill.

yaklang/binary-protection-bypass

Binary protection bypass playbook. Use when identifying and bypassing ASLR, PIE, NX/DEP, stack canary, RELRO, FORTIFY_SOURCE, CET, and MTE protections in ELF binaries to enable exploitation.

yaklang/browser-exploitation-v8

Browser and V8 exploitation playbook. Use when exploiting JavaScript engine vulnerabilities including JIT type confusion, incorrect bounds elimination, and V8 sandbox bypass to achieve renderer RCE and sandbox escape in Chrome/Chromium.

yaklang/business-logic-vuln

Entry P1 category router for business logic testing. Use when workflow abuse, race conditions, pricing flaws, or multi-step state attacks matter more than parser-level input injection.

yaklang/business-logic-vulnerabilities

Business logic vulnerability playbook. Use when reasoning about workflows, race conditions, price manipulation, coupon abuse, state machines, and multi-step authorization gaps.

yaklang/classical-cipher-analysis

Classical cipher analysis playbook. Use when encountering substitution ciphers, Vigenere, transposition, XOR, or encoded text in CTF challenges that requires frequency analysis, Kasiski examination, or known-plaintext cryptanalysis.

yaklang/clickjacking

Clickjacking playbook. Use when testing whether target pages can be framed, whether X-Frame-Options or CSP frame-ancestors are properly configured, and whether UI redress attacks can trigger sensitive actions.
