"The thing about this hack was that it was because of a weakness that is notable… so it's astonishing to see it in Amazon's bequest."
He said the entrance to voice records was a major concern, however was uncertain if different programmers could have thought about the weaknesses in explicit subdomains used to dispatch the assault.
"In spite of the fact that if the security specialists discovered it, I'm certain less conscientious individuals could have done likewise."
