A WebRTC leak is when a browser reveals your real IP address despite a proxy or VPN, because WebRTC requests ICE candidates that expose the true network — and in anti-detect setups, a leak links every profile to the operator's real IP.
WebRTC is designed for peer-to-peer connections, and its ICE mechanism gathers and exposes IP addresses directly to the page. A proxy hides the HTTP traffic but not necessarily the WebRTC candidates. When a browser leaks, the real IP becomes visible alongside the proxy identity. Browser fingerprinting for social media covers the broader signal set this fits into.
How Does the Leak Happen?
The page uses WebRTC to request ICE candidates, which include local and public IPs. A browser with WebRTC enabled returns the real IP regardless of the proxy in use. The leak is silent — the operator sees the proxy IP, but the page can also see the real one. Anti-detect browser fingerprint types lists where WebRTC handling sits in the browser stack.
Why Does It Cause Bans?
A leak exposes the same real IP across every profile using that browser. Platforms see one real IP behind many profiles with different proxies — a classic operator signature. Mobile proxies versus residential covers the proxy layer, but a WebRTC leak bypasses it entirely.
How Do You Prevent It?
Disable WebRTC or block ICE candidate retrieval, use a browser built for isolation that handles WebRTC correctly, or route at a layer WebRTC cannot bypass. Security research covers how platforms combine network and device signals. Testing for leaks before running accounts is essential.
Why Does This Matter at Scale?
The scale stakes are documented. Security research shows how platforms correlate network and device signals, and GeeTest's analysis covers the depth — one leak at scale links the network, which is why device-level network identity matters.
At scale, one leak can link an entire network. Every profile on that browser shares the real IP, so a single leak undoes the isolation that keeps accounts safe. How to manage 50 social profiles safely covers the operational checks that catch leaks before they cause damage.
How Conbersa Eliminates the Leak Problem
Conbersa eliminates WebRTC leaks entirely because each account runs on a physical device with its own SIM and mobile network. The device's real IP is the account's intended IP — there is no proxy to leak and no contradiction to expose. The platform sees exactly the identity the account is supposed to have. No spoofing, no leaks, no linkage.
We built Conbersa because a leak in a virtualized setup links everything. If your anti-detect setup is exposing the real IP behind your profiles, authentic device-level network identity removes the leak vector entirely.
