# Techniques du proxy Squid
## Proxys SQUID :
Si nous lançons une analyse sur le port 80, cela indique qu'il est **filtré** et non fermé :
### Méthode avec FoxyProxy
Voici le site normal où **rien n'apparaît**:
Nous créons un nouveau proxy avec **l'IP de la machine** et le port **3128**:
Avec **FoxyProxy**, le contenu apparaît :
### Méthode en ligne de commande :
Nous envoyons avec curl une requête au serveur web en utilisant le proxy de la machine via le port **3128**:
S'il demande **authentification**, faites-le comme suit :
## Reconnaissance des chemins (en passant par le proxy) :
Parfois, les **chemins n'apparaissent que** avec le proxy, voici un exemple de la façon de les voir :
```bash
gobuster dir -u http://192.168.71.131/ --proxy http://192.168.71.131:3128 -w /usr/share/SecLists/Discovery/Web-Content/directory-list-2.3-medium.txt -t 20
```
## Script Python automatisé :
```python
#!/usr/bin/python3
import sys, signal, requests
def def_handler(sig, frame):
print("/n/n[!] Exiting.../n")
sys.exit(1)
# Techniques de proxy Squid
signal.signal(signal.SIGINT, def_handler)
main_url = "http://127.0.0.1"
squid_proxy = {'http': 'http://192.168.71.131:3128'}
def portDiscovery():
common_tcp_port= {21, 22, 23, 25, 53, 80, 110, 111, 135, 139, 143, 443, 445, 993, 995, 1723, 3306, 3389, 5900, 8080, 8443, 8888, 5900, 6666, 6667, 6668, 6669, 7000, 10000, 32768, 32769, 32770, 32771, 32772, 32773, 32774, 32775, 32776, 32777, 32778, 32779, 49152, 49153, 49154, 49155, 49156, 49157, 49158, 49159, 49160, 49161, 49162}
for tcp_port in common_tcp_port:
r = requests.get(main_url + ':' + str(tcp_port), proxies=squid_proxy)
if r.status_code != 503:
print("/n[+] Port " + str(tcp_port) + "- OUVERT")
if __name__ == '__main__':
portDiscovery()
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://hacking-notes.jord4n.pro/fr/web-vulnerabilities/proxys-squid-attack/proxys-squid-techniques-pentesting-web.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
