This file is an instructional collection of DNS exploitation techniques (ECS spoofing, NSEC walking, IXFR tricks, rebinding, DNS tunneling) intended for CTFs or security research. It contains dual-use code that, if executed against systems without authorization, can be used to enumerate DNS zones, retrieve sensitive TXT records, perform DNS-based exfiltration decoding, and conduct DNS rebinding attacks. The code is not obfuscated and does not itself install backdoors or exfiltrate local machine data automatically, but it provides straightforward, actionable patterns that an attacker could reuse. Treat as high-risk to use against production/unauthorized targets and ensure use only in authorized testing environments.
