Description

In [your paper](https://thehackerblog.com/hacking-guatemalas-dns-spying-on-active-directory-users-by-exploiting-a-tld-misconfiguration/) you claim that this health report could be used to find TLDs with a vulnerability similar to the .gt one. Actually, there are several false positives because you just test if the MNAME in the SOA exists or not. You should also check if the SLD exists or not (if it exists, you cannot hijack it). Example: .fr is in the list. It is true the MNAME does not resolve but, because it is in an existing SLD, the attack is not possible.

Research direction

Start by locating the health-report check that tests whether the SOA MNAME resolves, then reproduce the reported .fr result and compare it with .gt. Done means an existing SLD such as .fr is not reported as vulnerable, while the genuinely exploitable .gt case remains detectable.
