1. A computer-implemented method of detecting potential steganography use comprising: identifying an electronic communication associated with a computer file; determining whether to analyze the communication for potential use of steganography to hide content in the computer file; analyzing a set of steganographic criteria to determine whether the computer file potentially includes hidden content in response to a determination to analyze the communication for potential use of steganography; determining that the computer file potentially includes hidden content in response to a determination that at least a portion of the steganographic criteria are satisfied; and determining that the computer file does not potentially include hidden content in response to a determination that at least a portion of the steganographic criteria are not satisfied.
