🕳 Ngrok: SSH Reverse Tunnel Agent

Did you know that you can run ngrok without even installing ngrok? You can start tunnels via SSH without downloading an ngrok agent by running an SSH reverse tunnel command:

ssh -i ~/.ssh/id_ed25519 -R 80:localhost:80 v2@tunnel.us.ngrok.com http

Hi Active Directory / ADCS hackers, I've published something! You can add the new SID extension manually if certificate templates allow for custom names: https://t.co/SndcHH3Kz7

👩‍💻 За кулисами Red Team. Интересные ситуации в проектах.

Друзья, рады вам сообщить, что уже в эту субботу, 1 апреля, мы проведём наш первый стрим в этом году!

Мы пригласили экспертов информационной безопасности, которые поделятся опытом работы в Red Team и расскажут о самых интересных и необычных ситуациях, с которыми они сталкивались в проектах по тестированию на проникновение. Вы узнаете, как они решают проблемы и справляются с непредсказуемыми ситуациями в процессе работы.

🌟 У нас в гостях:

🔹 @T3m3t_N0sc3 – гуру инфраструктурных пентестов и автор множества статей по Red Team;

🔹 @clevergod – вице-капитан команды Кодебай с колоссальным опытом в ред тим проектах;

🔹 @Riocool – основатель группы единомышленников RedTeam Brazzers, участник команды True0xA3;

🔹 @Acrono – создатель группы Telegram APT и автор нескольких CVE для Windows.

🎤 И, конечно же, ваш незаменимый ведущий – @puni1337!

⏰ Мы ждем вас 1 апреля в 17:00 по московскому времени!

👹 [ snovvcrash, sn🥶vvcr💥sh ]

Have been playing around with Domain Fronting via Fastly and discovered that you actually do not need to confirm the domain name ownership (by adding a CNAME) for the traffic to flow towards your IP. A bug or feature? 🤔

​​​⚛️ AtomLdr

A DLL loader with advanced evasive.

Features:
• DLL unhooking from \KnwonDlls\ directory, with no RWX sections
• The encrypted payload is saved in the resource section and retrieved via custom code
• AES256-CBC Payload encryption using custom no table/data-dependent branches using ctaes; this is one of the best custom AES implementations I've encountered
• Indirect syscalls, utilizing HellHall with ROP gadgets
• Payload injection using APC calls - alertable thread
• Api hashing using two different implementations of the CRC32 string hashing algorithm
• The total Size is 17kb

📜 Abusing Code Signing Certificates

Abusing code signing certificates is not new. In the past few years alone, it has proven to be an effective method of bypassing certain security controls to allow malicious software to run and look seemingly benign. This article describes code signing methods, as well as tools for copying the signature from legitimate PE files.
