| Layer | Challenge | FU10 Solution | |-------|-----------|----------------| | 1 | TLS Fingerprinting | Use curl-impersonate or modified pyhttpx to mimic Chrome’s exact cipher suites. | | 2 | IP Reputation | Rotate through ISP-grade residential proxies; avoid datacenter IPs. | | 3 | Behavioral Analysis | Record and replay real user sessions; inject random micro-movements. | | 4 | Canvas Fingerprint | Undetectable canvas randomization using html2canvas patches. | | 5 | AudioContext | Simulate realistic oscillator output via WebAudio API hooks. | | 6 | Request Timing | Add random ±200ms between resource loads (CSS, JS, images). | | 7 | Cookie Obsfucation | Parse and replay HttpOnly cookies with correct SameSite attributes. | | 8 | Shadow DOM | Use Element.shadowRoot traversal and polyfills for closed shadow roots. | | 9 | Rate Limiting | Distributed request queue with token-bucket algorithm. | | 10 | Payload Encryption | Reverse-engineer client-side encryption (often AES-CBC or RSA-OAEP) and replicate. | fu10 crawling
