North Korea got nuclear weapons technology from Pakistan, and possibly from China many years ago, not from India. Since India is not, unlike their neighbors to the north-west, bat-shit insane, they probably know that selling asymmetric weapons tech to countries that are bat-shit insane does not advance any of India's political or economic interests. As such they have probably already taken measures comparable to the US or France to secure their project rather than cold calling every drug exporting, famine inducing, hereditary dictatorship in their Rolodex.
And for similar reasons, nobody is any more worked up about this than if France tested a new missile, and maybe even a little less concerned than if the US developed a new ICBM.
