NetProbe: Net Recon & OSINT

NetProbe: Net Recon & OSINT is an ultimate mobile security suite designed to transform your Android device into a professional diagnostic station for asynchronous network security auditing, passive perimeter defense analysis (OSINT), and proactive infrastructure resiliency testing. This platform is engineered specifically for system administrators, network security engineers, and compliance auditors. Powered by a non-blocking Java NIO socket engine and the Jsoup DOM-parsing core, NetProbe performs deep infrastructure inspections completely offline-first, removing any reliance on third-party cloud middleware or external logging servers. CORE DIAGNOSTIC MODULES: 1. ADVANCED RECON CONVEYOR An automated multi-threaded pipeline that triggers an 11-stage deep perimeter audit with a single action to identify potential security misconfigurations: • GeoIP & Telemetry: Localized MaxMind database queries and connection latency verification. • DNS-over-HTTPS (DoH): Encrypted DNS record harvesting (A/TXT) via secure Cloudflare endpoints. • CDN Bypass Reveal: Scan underlying subdomain footprints (direct, mail, dev) to verify the configuration of backend server proxy protection behind Cloudflare. • Smart Port Scanner: Fast Scan utilizing an internal SQLite port catalog or a Full Scan across all 65535 sockets with adaptive thread pool configurations. • Jsoup Web Spider: Advanced DOM crawler mapping internal assets, interactive inputs, SEO tags, and underlying CMS infrastructure. • Contact OSINT Scraper: Extract public corporate emails, international phone numbers, and social handles directly from isolated DOM text to check for public data leaks. • Metadata Extractor: Fragmented HTTP Range queries fetching the first 64KB of remote documents to dissect hidden EXIF metadata leaks (author accounts, software versions). • Cryptographic SSL Auditor: Inspect TLS versions (up to TLS 1.3) and block ciphers for POODLE, BEAST, and ROBOT compliance vulnerabilities. • Web Security & CORS Inspector: Validation of CSP, HSTS, session cookie flags (HttpOnly, Secure, SameSite), and cross-origin resource sharing policy leakage risks. • Session Guard: Local offline Base64 decomposition of active JWT session tokens. • Seamless retrieval of robots.txt exclusions, passive crt.sh CT logs, and raw TCP WHOIS (Port 43). 2. LOAD RESILIENCY TESTING ENGINE A highly efficient multi-vector load generator running on a background Java NIO Selector to evaluate server stability under simulated high-user traffic conditions and peak request loads: • HTTP Flood Simulation: High-frequency burst of asynchronous HEAD/GET socket streams to verify web server request management. • Connection Starvation (Slowloris): Emulate slow client behavior to test server socket timeout thresholds and keep-alive limits. • Slow POST Simulation (RUDY): Check server session-clearing algorithms by transmitting POST forms slowly at 1 byte per 10 seconds to detect RAM exhaustion vectors. • Dynamic Target Hunting: Jsoup automation mapping calculation-heavy endpoints (search boxes, dynamic filters) to maximize load validation efficiency. • Persistent real-time HTTP liveness monitor. 3. ADVANCED CONFIGURATOR Take complete control over your toolkit layout. All thread capacities, NIO socket limits, custom DoH endpoints, and the Fast Scan port dictionary are driven by a dynamic NoSQL ORM (Squl) inside SQLite, managed by a sleek Material 3 Flexbox UI (ChipGroup) supporting interactive add/delete operations. DATA PRIVACY & INTEGRITY: NetProbe operates strictly on a Zero-Server architecture. Your target maps, harvested data logs, and profiles remain entirely inside your device's isolated local app sandbox. Complete data destruction can be executed instantly via standard Android OS storage management tools.
