From e4273f51502747f1ba95e6030d968f533b0695ee Mon Sep 17 00:00:00 2001 From: lockbitchat Date: Sat, 16 Aug 2025 20:58:42 -0400 Subject: [PATCH] Major Security Improvements: - Enhanced user fingerprinting with WebGL, Canvas, and Audio fingerprinting - Hardware binding to prevent F5/Ctrl+F5 abuse - Persistent storage across browser sessions (localStorage + sessionStorage) - Global demo session counter with 10 session limit per device - Multi-tab protection (max 2 tabs simultaneously) - Anti-reset protection with hardware mismatch detection Demo Session Protection: - Advanced fingerprint generation with CPU benchmarking - Enhanced validation with cryptographic verification - Automatic cleanup and session completion tracking - Cooldown periods between sessions (1min + 15min completion) - Weekly partial reset of global counters Fixes: - Fixed SessionTimer console spam after connection disconnect - Added missing registerEnhancedDemoSessionUsage method - Corrected method calls from generateUserFingerprint to generateAdvancedUserFingerprint - Implemented proper event handling for connection state changes WebRTC Improvements: - Added peer-disconnect, new-connection, and connection-cleaned events - Enhanced connection cleanup with proper UI notifications - Fixed SessionTimer state management during disconnections - Prevented infinite re-rendering and console logging Performance Optimizations: - Auto-save persistent data every 30 seconds - Periodic cleanup of old session data (every 6 hours) - Memory management for used preimages (10k limit) - Tab heartbeat system for multi-tab detection Testing: - Demo sessions now properly enforce limits - P2P anonymity maintained (no server validation) - Compatible with incognito mode restrictions - Resistant to common abuse techniques --- index.html | 1 - src/components/ui/Header.jsx | 2 +- src/components/ui/SessionTimer.jsx | 74 ++- src/network/EnhancedSecureWebRTCManager.js | 42 ++ src/session/PayPerSessionManager.js | 714 +++++++++++++++++---- 5 files changed, 697 insertions(+), 136 deletions(-) diff --git a/index.html b/index.html index d329c15..9094536 100644 --- a/index.html +++ b/index.html @@ -3244,7 +3244,6 @@ } try { - console.log('📤 Attempting to send message:', messageInput.substring(0, 100));
