-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I suppose one way would be to essentially take a leaf out of the p2p and malware playbooks...
Indroducing "Fast-flux p2p downloads with signed and checksummed packages" :P Seriously though, a distributed directory with metadata with signatures of the original provider available during searches could potentially work somewhat. Although, if the attacker has full control of the end point there is little they really can't do and blocking any downloads they want is up to them... however we can force them into the whole blacklisting arms race against packages rather than into the blacklisting domains which is somewhat easier which is what they quite often currently do. I don't have all the answers myself and my gut feeling is to just secure machines better (even if this ends up being a box with many sandboxes with well defined secure communications paths between apps, kinda like what vmware is aiming at atm) in the first place to stop 'evil-hacksaws' getting on the systems in the first place.
