Discovered in December 2024, asteroid 2024 YR4 was briefly considered the “most dangerous asteroid” in decades after scientists initially estimated it had a 3.1% chance of colliding with the Earth in 2032. Closer observations quickly ruled out a “city killer” scenario, but instead astronomers calculated there was a 4.3% chance that the moon lay in the path of impact.

While the idea of reverse FQDNs may seem straightforward, there are several potential gotchas that need to be addressed for this attack to work properly. It relies on the coordinated abuse of two different services: getting a free IPv6 tunnel and getting name servers that resolve the reverse DNS domain to the owner’s content. The IPv6 tunnel encapsulates IPv6 traffic and sends it over IPv4, but the actor doesn’t need or use the tunnel. It’s simply an easy way to get administrative access to a free IPv6 range. The tunnel isn’t surprising, but the ability to claim ownership of a .arpa domain with a DNS provider is. Given the reserved nature of the .arpa TLD, we wouldn’t expect it to be as easy as entering the domain in a web form. When we evaluated a few DNS providers to check if they were vulnerable, this was the point in the process that was ultimately the determining factor. If the provider prevented us from claiming ownership of a .arpa domain, either by explicitly denying the request or by the request failing, we considered the DNS provider not vulnerable.
