Screenshot of the April Fool's Day implementation of the RFC 5314 'Evil Bit' protocol.

The evil bit is a fictional IPv4 packet header field proposed in RFC 3514, a humorous April Fools' Day RFC from 2003 authored by Steve Bellovin.

The RFC recommended that the last remaining unused bit in the IPv4 packet header be used to indicate whether a packet had been sent with malicious intent, thus making computer security engineering an easy problem -- simply ignore any messages with the evil bit set.
