Working with Exploit Payloads
Metasploit helps deliver our exploit payloads against a target system. When creating an Exploit Payload, we have several things to consider, from the operating system architecture, to anti-virus, IDS, IPS, etc. In evading detection of our exploits we will want to encode our payloads to remove any bad characters and add some […]

Coding Exploit Targets in your Metasploit Module
Exploits define a list of targets that includes a name, number, and options. Targets are specified by number when launched.
Sample Target Code for an Exploit Module:
‘Targets’ =>

Working with Exploit Mixins
Exploit::Remote::Tcp
Code:
lib/msf/core/exploit/tcp.rb
Provides TCP options and methods.
Defines RHOST, RPORT, ConnectTimeout
Provides connect(), disconnect()
Creates self.sock as the global socket
Offers SSL, Proxies, CPORT, CHOST
Evasion via small segment sends
Exposes user options as methods – rhost() rport() ssl()
Exploit::Remote::DCERPC
Code:
lib/msf/core/exploit/dcerpc.rb
Inherits from the TCP mixin and has the following methods and options:
dcerpc_handle()
dcerpc_bind()
dcerpc_call()
Supports IPS evasion methods with multi-context BIND […]

Formatting our Exploit Module
The format of an Exploit Module in Metasploit is similar to that of an Auxiliary Module but there are more fields.
There is always a Payload Information Block. An Exploit without a Payload is simply an Auxiliary Module.
A listing of available Targets is outlined.
Instead of defining run(), exploit() and […]

Writing your own TFTP Fuzzer Tool
One of the most powerful aspects of Metasploit is how easy it is to make changes and create new functionality by reusing existing code. For instance, as this very simple Fuzzer code demonstrates, you can make a few minor modifications to an existing Metasploit module to […]
