Abstract
A method for detection of phishing attempts in received electronic mail messages includes retrieving the source code, displayed text, and a list of all specified addresses contained within the source code of a received electronic message. Visual character normalization is applied to each specified address to develop all possible address combinations and to form a normalized address list. The specified addresses are removed from the normalized address list to create a revised address list, upon which comparison tests are performed to determine if each address in the revised address list is from a valid source. The recipient of the electronic message is informed of any message found to be from an invalid source.
