Abstract

Methods and systems for detecting suspicious electronic communications, such as electronic mail (email) messages containing, originated or purportedly originated from misspelled and/or deliberately misleading addresses, are provided. According to one embodiment, an electronic communication, such as an electronic mail (email) message, is scanned to determine whether the electronic communication contains one or more suspicious addresses or represents a suspicious traffic pattern. If the electronic communication is determined to contain one or more suspicious addresses or is determined to represent a suspicious traffic pattern, then the electronic communication is handled in accordance with an electronic communication security policy associated with suspicious electronic communications. For example, an event may be logged, the electronic communication may be dropped or quarantined, the communication may be tagged as spam or possible phishing and/or an end user may be alerted to the existence of the one or more suspicious addresses.
