Why dump directly from memory?

In most linux environments users can access the memory of processes, this allows attackers to harvest credentials, private keys, or anything that isnt suppose to be seen but is being processed by a program in clear text.

Features

Ability to enter regex lists
Clear and Readable Display
Check if Memory Range is Writable with Current Permissions
Output in XML and HTML along with the default output (process name:result)
Ability to Mass Scan Every Proccess or a Specific PID
Able to choose memory sections to scan
Ability to Show Detailed Process Information
Ability to Scan Process Environment Files
Memory dumps automatically removes unicode characters which allows for processing with other tools or manually
