Als Backdoor (auch Trapdoor, selten Hintertür) bezeichnet man einen (oft vom Autor eingebauten) Teil eines Computerprogrammes, der es Benutzern ermöglicht, unter Umgehung der normalen Zugriffssicherung Zugang zum Computer (oder einem Computerprogramm) zu erlangen.Eine Variante besteht darin, in einem System fest vorgegebene, nur dem Ersteller des Systems bekannte Passwörter oder andere versteckte Funktionen, die ein Login ohne die sonst übliche Authentifizierung ermöglichen, einzubauen. Bekanntes Beispiel hierfür ist wohl das von Award Software über mehrere Jahre vergebene BIOS-Universalpasswort „lkwpeter“ (wobei es sich nicht um das Paßwort handelte, sondern um ein einprägsames Wort, was zum richtigen Hash führte). Publikumswirksam demonstriert wurde der Einsatz einer Hintertür auch im Kinofilm Jurassic Park.

Le backdoor in informatica sono paragonabili a porte di servizio che consentono di superare in parte o in toto le procedure di sicurezza attivate in un sistema informatico. Queste "porte" possono essere intenzionalmente create dai gestori del sistema informatico per permettere una più agevole opera di manutenzione dell'infrastruttura informatica, e più spesso da cracker intenzionati a manomettere il sistema. Possono anche essere installate autonomamente da alcuni malware (come virus, worm o trojan), in modo da consentire ad un utente esterno di prendere il controllo remoto della macchina senza l'autorizzazione del proprietario.
