The Jargon File (version 4.4.7, 29 Dec 2003):

zombie
 n.

    1. [Unix] A process that has died but has not yet relinquished its process
    table slot (because the parent process hasn't executed a wait(2) for it
    yet). These can be seen in ps(1) listings occasionally. Compare orphan.

    2. A machine, especially someone's home box, that has been cracked and is
    being used as part of a second-stage attack by miscreants trying to mask
    their home IP address. Especially used of machines being exploited in large
    gangs for a mechanized denial-of-service attack like Tribe Flood Network;
    the image that goes with this is of a veritable army of zombies mindlessly
    doing the bidding of a necromancer.
