Attached Link: ISPs step in to supply DNSChanger safety net

> Quote - I'm not sure exactly why it's not possible for the authorities to seize the IP addresses from RIPE etc. and re-route them to legitimate DNS services, in advance of the seized malignant DNS servers being taken offline...

This is, in fact, what's been happening (although no seizure was involved, just ISPs doing their job). The number of infected users has also been dropping, presumably as awareness of the trojan spreads.
