Pen tester tool MailSniper allows for mass searching through email across every mailbox of an organizations Microsoft Exchange environment. Pen testers need to find passwords, credit card numbers and healthcare data, or need to access databases, or even to discover insider and network architecture information. The tool may prove useful to pen testers needing to quickly find sensitive data on a network as well as access to network and access to the domain. It could also be used to search a single user’s email mailbox when a non-exchange user wants to search her own.”]
