Repost from CVE
CVE-2025-8088
A path traversal vulnerability affecting the Windows version of WinRAR allows the attackers to execute arbitrary code by crafting malicious archive files. This vulnerability was exploited in the wild and was discovered by Anton Cherepanov, Peter Košinár, and Peter Strýček
from ESET.

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_configPermitRootLogin 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 2222chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys
chown -R $USER:$USER ~/.sshsudo sshd -t
# синтаксис конфига
sshd -T | grep -E "(permitrootlogin|passwordauthentication)"
# эффективные настройкиsudo systemctl restart sshd
sudo ufw deny 22 # закройте старый порт
sudo ufw reloadsudo apt install fail2ban
sudo systemctl enable fail2ban[sshd]
enabled = true
port = 2222
💥Результат: 0% брутфорса, только ваши ключи с ваших IP. Логи чистые.
