SAD DNS: Researchers pull source code as DNS cache poisoning technique deemed ‘too dangerous’
The DNS cache poisoning attack was discovered in 2008 and fixed, but researchers found a way to bypass mitigations. Attackers can again poison the cache of DNS resolvers and cause them to return a malicious spoofed IP address instead of the real IP of a domain. It is so severe that the source code to reproduce it was pulled after its publication and DNS providers like Cloudflare are working on new mitigations.
