Vulnerabilities & ExploitsUDP Proxies and QUIC Protocol: How Real IP Addresses Leak Through Anti-Detect Browsers
Anti-detect browser users relying on UDP-capable proxies face a hidden risk of real IP leakage when the browser fails to properly route UDP traffic. The QUIC protocol, which powers HTTP/3, runs over UDP and enables features like 0-RTT handshakes, independent streams, and connection migration that can bypass proxy routes. WebRTC connections using ICE, STUN, and TURN further increase exposure because they often attempt direct UDP paths outside the configured SOCKS5 proxy. Without deep network stack control such as TUN interfaces or socket interception, browsers may send WebRTC and QUIC packets through the host's real network interface. Aurorium Browser claims to solve this by natively supporting UDP proxying so that both QUIC and WebRTC traffic stays inside the tunnel. The article stresses that simply disabling WebRTC or forcing HTTP/2 fallback is insufficient and can itself create detectable anomalies for anti-fraud systems.
Deploying Self-Hosted Hysteria 2 Proxy on Debian-Based Linux VPS via Terminal
A detailed guide explains how to set up a personal Hysteria 2 proxy server on a KVM VPS running Debian or Ubuntu without any web panels. The process begins with generating ed25519 SSH keys, hardening the sshd_config file, and restricting access with ufw to only TCP port 22 and UDP port 443. Hysteria 2 is downloaded from GitHub, made executable, and configured using a TOML file that enables salamander obfuscation and a self-signed TLS certificate. A custom systemd unit ensures the service restarts on failure. The client configuration includes SHA256 pinning of the server certificate to prevent MITM attacks. The guide emphasizes manual CLI operations that apply equally to other services such as Nginx and stresses checking local laws before deployment.
