fictional character, possibly created by Joe Talmadge, originally used or referred to in Usenet news postings, portraying the stereotypical newbie (novice or newcomer) on the Net, generally a blackhat wannabe. Postings from B1FF typically use capital letters, deliberately misspell words, and replace letters with non-alphabetic characters (dudes=D00Dz). Because such people tend to claim !33t (elite) status, !33t has come to replace B1FF in more recent writings, although there are many variations in spelling for both terms. B1FF is probably the preferred one, since it looks like hexadecimal representation. No relation to the biff mail notification utility.

It is activated in some innocent-appearing manner; for example, a key sequence at a terminal. Invocation of the backdoor can also be done by sending a specific packet to a network port; see RAT. Software developers often introduce backdoors in their code to enable them to reenter the system and perform certain functions; see maintenance hook. The backdoor is sometimes left in a fully developed system either by design or by accident. Synonymous with trap door, which was formerly the preferred usage. Usage back door is also very common.
