Just change your local resolver to be authoritative for the domain(s) in question, and bob&amp;#x27;s your uncle.&lt;p&gt;But next they&amp;#x27;ll likely use more domains, and more expensive ones, so that random security researchers can&amp;#x27;t just expense the registration on the corporate credit card. I know .ng costs 50k, but .np might be pretty comical to deploy if you&amp;#x27;re not really worried about a global off switch.</text><parent_chain><item><author>eterm</author><text>Under that same assumption of assuming maximum damage, what was the motivation for the malware author to put in a killswitch?</text></item><item><author>ufmace</author><text>I would think not.
