Key — Robotrader License

| Attack | Mitigation | |--------|-------------| | (NOP out jump on license fail) | Obfuscated control flow + checksum verification scattered across execution | | Keygen creation (reversing signature algorithm) | Use secure hardware for signing; never embed private key in software | | Memory dumping (extract valid license after validation) | Encrypt license in memory with a runtime-derived key | | Emulation of license server (local fake server) | Pin TLS certificates; use certificate pinning and nonce challenges |
