What Is a WebRTC Leak?
A WebRTC leak occurs when your real IP address is exposed through the WebRTC (Web Real-Time Communication) feature in modern browsers.
Even if you’re using a VPN, proxy, or other anonymity tools, certain websites can still request your device’s network information via WebRTC and reveal your true IP. This creates a serious risk for privacy, security, and multi-account operations.
Why Do WebRTC Leaks Happen?
- Built-in browser feature: Most browsers (Chrome, Firefox, Edge) have WebRTC enabled by default to support real-time communications like video calls or file transfers.
- Direct IP requests: WebRTC attempts to establish peer-to-peer connections and fetches network interfaces directly, bypassing VPN or proxy routing.
- Lack of restrictions: Standard browsers don’t strictly limit these requests, which means users often leak their real IP without knowing.
Risks of WebRTC Leaks
- Account Linking – Platforms can detect that multiple accounts belong to the same user by comparing IPs.
- Privacy Exposure – Malicious websites or trackers can access your true location and ISP details.
- Account Suspensions – Platforms like Amazon, Facebook, or Google may flag and ban accounts if they detect mismatched or hidden IP activity.
Real-World Examples
- A Facebook Ads manager used a VPN to log into multiple accounts, but due to a WebRTC leak, Facebook detected the same real IP and banned all accounts.
- A cross-border Amazon seller managed multiple stores on different proxies. Since WebRTC wasn’t disabled, Amazon detected their real network and restricted accounts.
- With MasLogin Antidetect Browser, users can block WebRTC leaks, ensuring each account runs in a fully isolated environment and preventing real IP exposure.
Who Should Care About WebRTC Leaks?
- E-commerce sellers – Amazon, Shopee, eBay, Lazada store operators
- Social media managers – Running multiple accounts on Facebook, Instagram, TikTok, Twitter (X)
- Affiliate marketers – Working with proxies and multiple accounts
- Privacy-conscious users – Anyone concerned about IP or geolocation exposure
