4RD Kleinanzeigen Suite | Source Code Leak. inkl. ThreatMetrix Bypass!!


Recommended Posts

 Gesamtprojekt (4RD Suite) Source Code!

Inhalt:

  - Portal (Portal/app_portal.py, 385 LOC, Port 8000): Flask-App für User-Reg, Login, Krypto-Payments, Subscriptions,
  Referrals. Templates: Shop, Marketplace, Profile, Invoice.


  - KLZ (KLZ/app_kleinanzeigen.py, 1128 LOC, Port 8001): Flask-API + UI für Account-, Ad-, Chat-Verwaltung. Schreibt
  Tasks in SQLite-Queues.


  - Client Loop (Client/loop.py, 669 LOC): Worker-Daemon, pollt Task-Tabellen, dispatcht in Worker-Module.
  - DB: SQLite (4rd.db), migriert von MySQL — Adapter sqlite_adapter.py, alte mysql_instance.py-Wrapper

 

  Anti-Detection-Stack (Client/client/utils/)

  1. ThreatMetrix.py (310 LOC) — Reverse-Engineered LexisNexis-iOS-SDK:
    - create_session() durchläuft fetch_mobile_conf → h46_metrix → submit_device_check
    - AES-CBC mit CRC32-derived Key, ECDSA-P256-Signatur, gzip-Payloads, XOR-ja-Encoding
    - Liefert X-EBAYK-WENKSE-SESSION-ID für die Kleinanzeigen-API


  2. solver.py — Akamai BMP-Sensor (X-acf-sensor-data) für api.kleinanzeigen.de
  3. unique_device.py — Generiert plausible iPhone-Hardware-Fingerprints (IP-abhängig)
  4. noble_tls / tls_client — TLS-JA3/JA4-Fingerprint-Spoofing (Safari iOS 18)
  5. Residential Proxies (proxyList.txt, anyip.io) — DE-geo-routing pro Account
