MailSniper — Attack Tool
MailSniper is a penetration testing tool for searching through email in a Microsoft Exchange environment for specific terms (passwords, insider intel, network architecture information, etc.). It can be used by a non-administrative user to search their own email, or by an Exchange administrator to search the mailboxes of every user in a domain.
