Add RAT category and add fileless-xec into it

[ariary]

What is RAT tools category?

A remote access Trojan (RAT) is a malware program that includes a back door for administrative control over the target computer.

I think this kind of tools could not be placed into other category and are part of the arsenal of a pentester.

What is fileless-xec?
fileless-xec could be used as a stealth dropper (kind of trojan that has been designed to "install" some sort of malware to a target system). It enable us to retrieve a remote binary file and execute it in one step without dropping binary on disk.

• The binary file is not mapped into the host file system
• The execution program name could be customizable
• Bypass 3rd generation firewall could be done with http3 support
• Bypass network restriction with icmp support
• Handle different type of connection with remote (client or server)
