Don't beleive the listing of hijacked netblocks @ Spamhaus, its maintained by someone who doesn't seem to know the difference between spammer-hijacked netblocks & netblocks assigned by ISPs to thier users.
Actually, Spamhaus is very good at detecting zombies. The link provided is not strictly hijacked networks, though. In all cases, Spamhaus tends to side on a "questionable" zombie, as sometimes it's difficult to tell if a network was truly hijacked. As known spamhausen do hijack more networks and demonstrate a track record, it does lead to more easily detecting when a network or AS has been hijacked. In all cases, the list is about spam, not netblock hijacks. -Jack
