ABSTRACT:
Method and apparatus for detecting web-based electronic mail in network traffic is described. In some examples, web pages are extracted from the network traffic. Fields in each page of a group of the web pages that share a documents structure are identified. A statistical analysis of the fields of each page in the group of web pages is performed to identify any electronic mail (e-mail) fields. The group of web pages is indicated to include web-based e-mail messages if the fields of each page in the group of web pages include at least one e-mail field.
