🪄 Red Wizard This tool automates the deployment of a comprehensive infrastructure with redirectors, backend systems, phishing relays, OSINT machines, and more. It is designed to be user-friendly, providing wizards to walk administrators and Red Team operators through the deployment process. The infrastructure is also self-documenting, making the sharing of all relevant details to the team of operators an effortless task. 🌐 Details: https://www.secura.com/blog/red-wizard-1 #redteam #relay #infrastructure #phishing

Шпаргалка по быстрому развертыванию старой Убунты Зачем? Статистика не врет – бо́льшая часть проломов с внешки начинается с дырявого веба. Веб же, в основном, крутится на *NIX-ах, и чаще всего, на жесть как не до конца обновленных. К сожалению (нет, на самом деле, к частью), реал-лайф отличается от CTF-таска, поэтому нестандартного SUID-ника / сплойтабельной cron-задачи / нестойкого sudo -l правила найти удается далеко не всегда, а залутаться от рута ой как хочется. Следовательно, если сходу не взлетает PwnKit, linPEAS (по секрету) запускать никто не будет, ведь ядерным сплоитом проще и быстрее. Однако, предвосхищая контраргументы на тему небезопасности их применения, ядерные уязвимости требуют бережного использования в проде. Обычно под этим подразумевается предварительное тестирование оных на подготовленном стенде с продовым сетапом (ревизия ОС, версия ядра). На примере Убунты покажем, как быстро задеплоить такой стенд. 1. Смотрим ОС и ядро на таргете:

$ cat /etc/os-release
$ uname -a

2. Идем на old-releases.ubuntu.com и хватаем нужный ISO-шник торрентом, разворачиваем на ВМ. 3. Меняем репозитории системных пакетов на архивные:

$ sudo sed -i -re 's/([a-z]{2}\.)?archive.ubuntu.com|security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list
$ sudo apt-get update

4. Накатываем нужное ядро:

$ sudo apt-get install linux-image-$(uname -r)

5. Правим настройки GRUB, чтобы при загрузке иметь возможность свичнуть ядро:

$ gksudo gedit /etc/default/grub
--> GRUB_TIMEOUT=-1
--> #GRUB_HIDDEN_TIMEOUT=0
$ sudo update-grub
$ sudo reboot  # (on boot select the kernel from "Previous Linux versions")

6. Ставим метапакеты компиляции и gcc-multilib на случай, если древний сплоит будет собираться с -m32:

$ sudo apt-get install build-essential gcc-multilib

В среднем процесс занимает не более 15 минут вместе с загрузкой образа и адаптацией команд выше под тестируемый дистрибутив. P. S. Если версия ОСи достаточно старая, чтобы libssl не дал скачать сорцы с Гитхаба с помощью wget/curl (i. e., не поддерживает хотя бы TLSv1.2), репозитории можно клонировать, отключив в клиенте гита проверку SSL-ей (для гетов/курлов такое не прокатит – все равно обосрутся):

$ export GIT_SSL_NO_VERIFY=1
$ git clone https://github.com/<EXP_AUTHOR>/<EXP_REPO>

🔐 Exploiting SCCM’s AdminService API for Site Takeover 🔐 Extensive research into SCCM services has revealed a security flaw within the AdminService API, exploiting the authentication process and leading to unauthorized access. The AdminService API, backed by Microsoft Negotiate authentication, could be leveraged by malicious actors for privilege escalation, granting unauthorized Full Administrator privileges on the targeted site. 🌐 Details: https://posts.specterops.io/site-takeover-via-sccms-adminservice-api-d932e22b2bf #ad #sccm #site #takeover

Ⓜ️ Metabase Pre-auth RCE Earlier this week, it was reported that Metabase open source before 0.46.6.1 and Metabase Enterprise before 1.46.6.1 has a vulnerability that allows attackers to execute arbitrary commands on the server, at the server's privilege level. Authentication is not required for exploitation. This vulnerability was designated as CVE-2023-38646.

TGSThief I think a lot of people have seen the project GIUDA . It is an interesting way to get the TGS of a user whose logon session is just present on the computer. The problem is that its code is written in Pascal, so I had to rewrite the project in C++. How to use: Just run the tool and select the desired logon session! The tool will automatically escalate privileges and request a TGS. Advantages: - We do not need to run the code on behalf of the system. Run the program as a local administrator, the privilege escalation will happen automatically. - I also added SPN validation through regex, so there is less chance of making a mistake and not getting TGS. - The TGS ticket is optionally injected into the logon session where the tool is running. The TGS ticket is simply output in base64 for convenience, and only embedded if required. - It is not necessary to run the tool ten times to see the LUID. You can now select the LUID you want from the drop down list. Thanks to: @Michaelzhm

Если есть привилегия SeTcbPrivilege (а локальный админ может ее активировать), то можно запросить TGS билет для любого авторизованного в системе пользователя без указания его пароля. Интересный сценарий... https://github.com/foxlox/GIUDA #ad #pentest #redteam #soft #git

🎯 Meterpreter vs Modern EDR This blog post explains how making minor adjustments to the Meterpreter shellcode dropper can effectively evade modern EDRs. Three modifications are employed on the Meterpreter reference dropper. These modifications involve encrypting the Meterpreter shellcode using the XOR algorithm, incorporating valid metadata via a manifest file, and relocating the Meterpreter shellcode from the .text section to the .data section. https://redops.at/en/blog/meterpreter-vs-modern-edrs-in-2023 #av #edr #meterpreter #xor #cpp
