i hijacked some telephone infrastructure of a few islands over the span of multiple months; and accidentally logged information of a few hundreds of thousands of phone calls going to military bases in the process..
it's a really really silly story :P
@lina Thanks for the writeup and explanation of what you did. I’ve worked with DNS for decades and did some experiments with public ENUM back in the 2000s when it was all new.. and I am sadly not surprised by the neglect you found.
Public ENUM was an interesting idea… but the ease for spammers to call people by just walking the DNS tree doomed it (there was even a script that made that trivial).
Now, *private* ENUM inside telcos was a HUGE usage. Probably still is!
@lina silly story, awesome writeup! thanks for the research and the lulz
