Under normal circumstances, this [a way that the BlackBerry Router can be shut down using a flaws in the routing protocol] should be viewed as an internal-only vulnerability because the BlackBerry Router will only communicate with the BlackBerry Infrastructure. An external user attempting to exploit this needs to manipulate Domain Name System (DNS) queries. This results in a denial of service and does not require any further action to interrupt connectivity to external services. Enterprises can mitigate the risk of DNS hijacking by creating static entries in their local DNS or HOSTS tables for the BlackBerry Infrastructure.

ISP server attack
Valid reply with poisoned additional information. False .com server address installed in ISP servers - 10% of servers vulnerable
Hypothetical attack: a new signature is added by X, whose public key resides at a false domain Y. A commercially successful DNS attack last year used the same vulnerabilities and topology.
