## FTP Bounce - Scanning
### Manual
1. Conecte-se ao FTP vulnerável
2. Use \*\*`PORT`\*\* ou **`EPRT`** (mas apenas 1 deles) para estabelecer uma conexão com o _\_ que você deseja escanear:
`PORT 172,32,80,80,0,8080`\
`EPRT |2|172.32.80.80|8080|`
3. Use **`LIST`** (isso apenas enviará para o _\_ conectado a lista de arquivos atuais na pasta FTP) e verifique as possíveis respostas: `150 File status okay` (Isso significa que a porta está aberta) ou `425 No connection established` (Isso significa que a porta está fechada)
1. Em vez de `LIST`, você também pode usar **`RETR /file/in/ftp`** e procurar por respostas semelhantes `Open/Close`.
Exemplo usando **PORT** (porta 8080 de 172.32.80.80 está aberta e porta 7777 está fechada):

### **nmap**
```bash
nmap -b :@
nmap -Pn -v -p 21,80 -b ftp:ftp@10.2.1.5 127.0.0.1 #Scan ports 21,80 of the FTP
nmap -v -p 21,22,445,80,443 -b ftp:ftp@10.2.1.5 192.168.0.1/24 #Scan the internal network (of the FTP) ports 21,22,445,80,443
```
