Trap Door or Trapdoor

Trapdoor (trap door), also called a back door, is an entrance into a network, system or program created by the system’s designers or managers. However, attackers often use back doors that they detect or install themselves, as part of an exploit. In some cases, a worm is designed to take advantage of a back door created by an earlier attack. For example, Nimda gained entrance through a back door left by Code Red.
