Bypassing EDR in a Crystal Clear Way This blog takes you from how C2 payloads actually work under the hood all the way to building a fully evasive reflective loader that bypasses one of the best EDR's, covering module overloading with .pdata registration, NtContinue entry transfer, API call stack spoofing with Draugr, sleep masking, and Crystal Palace YARA signature removal. Every technique explained from why it exists, not just how it works.

🔒 Безопасная настройка OpenSSH: запрет root, ограничение IP, ключи 99% взломов SSH из-за дефолтных настроек. Боты бьют по root:22 24/7. За 10 минут превратим sshd_config в крепость: без root, только ключи, белый список IP. 1️⃣Бэкап и редактирование /etc/ssh/sshd_config
sudo cp /etc/ssh/sshd_config /etc/ssh/sshd_config.bak
sudo nano /etc/ssh/sshd_config
2️⃣ Запрет root и паролей PermitRootLogin no PasswordAuthentication no PubkeyAuthentication yes 3️⃣Ограничение по IP (AllowUsers) # Только с вашего офиса и VPS AllowUsers admin@192.168.1.100 admin@203.0.113.5 deploy@10.0.0.50 # Или подсети AllowUsers *@203.0.113.0/24 Root всё равно заблокирован, но можно @ваш_IP для root при необходимости. 4️⃣ Смена порта (обязательно) Port 2222 Боты сканируют 22, ваш 2222 игнорят. Откройте в ufw: sudo ufw allow 2222/tcp 5️⃣ Современные алгоритмы 2025 # Только сильные шифры Ciphers chacha20-poly1305@openssh.com,aes256-gcm@openssh.com,aes128-gcm@openssh.com MACs hmac-sha2-512-etm@openssh.com,hmac-sha2-256-etm@openssh.com KexAlgorithms curve25519-sha256,[email protected] 6️⃣ Таймауты и лимиты ClientAliveInterval 300 ClientAliveCountMax 0 MaxAuthTries 3 LoginGraceTime 30 MaxSessions 2 🔑 Генерация и настройка ключей На локальной машине:
ssh-keygen -t ed25519 -C "admin@server" -f ~/.ssh/server_key
ssh-copy-id -i ~/.ssh/server_key.pub [email protected] -p 2222
Права на сервере:
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys
chown -R $USER:$USER ~/.ssh
Тестирование перед рестартом
sudo sshd -t  
# синтаксис конфига
sshd -T | grep -E "(permitrootlogin|passwordauthentication)"  
# эффективные настройки
Подключитесь с нового терминала: ssh -p 2222 admin@server 🔄Применение
sudo systemctl restart sshd
sudo ufw deny 22  # закройте старый порт
sudo ufw reload
🚨Fail2ban как вишенка
sudo apt install fail2ban
sudo systemctl enable fail2ban
В /etc/fail2ban/jail.local: [sshd] enabled = true port = 2222 💥Результат: 0% брутфорса, только ваши ключи с ваших IP. Логи чистые. 🖥 CodeGuard: Academy | Чат
