The system combines a sophisticated proxy connectivity Checker with a Microsoft account Checker engine, built for reliability, scalability, and production deployment.
Key Features:
- Multi-Protocol Support: HTTP/1.1 with TLS 1.2/1.3, automatic redirect handling
- Intelligent Proxy Rotation: Failure-based proxy blacklisting with 5-strike system
- Subscription Detection:
- GamePass identification
- Active subscription enumeration
- Service availability checking
- Comprehensive Result Categorization:
- VALID: Successfully authenticated accounts
- INVALID: Invalid credentials
- CUSTOM: 2FA-enabled accounts
- RECOVER_OR_ABUSE: Security-challenged accounts
- ERROR_RETRY: Transient failures
- Progress Persistence: JSON-based checkpointing with line-by-line resume
- Domain Validation: Microsoft-specific domain filtering (350+ domains supported)
Enhanced Security Posture Assessment:
- Multi-Factor Detection: Automatically identifies 2FA-enabled accounts for security maturity evaluation
- Security Challenge Recognition: Detects accounts under recovery or abuse investigation by Microsoft
- Domain-Specific Validation: Filters only Microsoft domains (350+ domains) for targeted security testing
Comprehensive Account Intelligence:
- Subscription Enumeration: Identifies active GamePass and other Microsoft service subscriptions
- Entitlement Analysis: Distinguishes between accounts with active services vs. no active services
- Service-Level Insights: Provides granular visibility into account service portfolios
High-Performance Architecture:
- Parallel Processing: Configurable thread pool (1-100 threads) for optimal throughput
- Proxy Rotation Intelligence: 5-strike failure system with automatic blacklisting of malfunctioning proxies
- Connection Pooling: Optimized HttpClient reuse with TLS 1.2/1.3 support
Advanced Proxy Management:
- Smart Proxy Selection: Dynamic proxy rotation with quality-based routing
- Failure Resilience: Automatic proxy failure detection and replacement
- Seamless Integration: Direct import from Proxy Checker's validated proxy lists
