+	    works by targeting an Unbound instance. Unbound is queried for a
+	    rogue domain name when the cached delegation information is about to
+	    expire. The rogue nameserver delays the response so that the cached
+	    delegation information is expired. Upon receiving the delayed answer
+	    containing the delegation information, Unbound overwrites the now
+	    expired entries. This action can be repeated when the delegation
+	    information is about to expire making the rogue delegation
+	    information ever-updating.</p>
+	  <p>novel type of the "ghost domain names" attack. The vulnerability
+	    works by targeting an Unbound instance. Unbound is queried for a
+	    subdomain of a rogue domain name. The rogue nameserver returns
+	    delegation information for the subdomain that updates Unbound's
+	    delegation cache. This action can be repeated before expiry of the
+	    delegation information by querying Unbound for a second level
+	    subdomain which the rogue nameserver provides new delegation
+	    information.</p>
