So you want to exploit ADCS ESC8 with only netexec and ntlmrelayx ? Fear not my friend, I will show you how to do it 👆

NetExec now supports "Pass-the-Cert" as an authentication method, thanks to @_dirkjan original work on PKINITtools ⛱️

imo way to complicated to extract the ntds, once you got a user with backup privilege group just do:

nxc smb dc -u user -p pass -M backup_operator

Keeping the blog alive. For people who may be unaware, you can embed a file in a C/C++ program without needing to make a giant byte array in a header file for it. Kind of went a little bit overboard on the detail with this lol but it's pretty useful

New blog from me on using CLR customizations to improve the OPSEC of your .NET execution harness. This includes a novel AMSI bypass that I identified in 2023. By taking control of CLR assembly loads, we can load assemblies from memory with no AMSI scan.

And to be precise, it affects the GetComputernameW itself, and not just one tool using it.

🔍 Exploring WinRM plugins for lateral movement

In this blog, the process of leveraging WinRM plugins to perform lateral movement to other systems is explored. Additionally, the use of the CIM_LogicFile WMI class to bypass certain tricky detections by Microsoft Defender is examined. Finally, all the logic is incorporated into a Cobalt Strike BOF.

Сегодня я увидел в нескольких каналах информацию про атаку Targeted Timeroasting и очень вдохновился ею.
В двух словах, что такое атака Timeroasting - Это атака, позволяющая получить хеш пароля машинной учетной записи. В целом, мы знаем, что это для нас бесполезно, т.к. пароль машины чаще всего очень длинный и сложный. Но есть сценарии, когда пароль все таки бывает простой и, в совокупности с атакой pre2k, можно построить интересный вектор. Об этом в своем блоге недавно писал @snovvcrash.

Суть атаки Targeted Timeroasting немного в другом: если у нас есть права GenericWrite на объект пользователя, то мы можем превратить этого пользователя в компьютер (что?) и запросить хеш для него. Превратить пользователя в компьютер можно двумя простыми шагами:
1. Меняем userAccountControl на 4096 (UF_WORKSTATION_TRUST_ACCOUNT)
2. Переименовываем sAMAccountName в тоже имя, но со знаком $ на конце
После этих действий сервис времени будет уверен, что это теперь компьютер и отдаст вам хеш.
Хорошо, как можно это использовать?

1 Сценарий.
У нас есть права Domain Admins и не хочется шуметь с помощью атаки DcSync, тогда можно запустить Targeted Timeroasting на всех пользователей и вы получите хеши учеток, которые потом надо будет еще сбрутать.

2 Сценарий.
Захватили учетку HelpDesk. Чаще всего у этой учетки есть права GenericWrite на половину домена. CA в домене нет, значит не провести атаку Shadow Creds. Проведя атаки Targeted Kerberoasting или Targeted AsReproasting мы получим билеты, которые нет возможности побрутить по большим словарям. А с помощью атаки Targeted Timeroasting мы, во-первых, не сильно нашумим на SIEM (не факт, конечно), а во-вторых, получим хеши, которые можно перебирать с чудовещной скоростью.
Остальные сценарии придумайте сами :)

Свежий ресерч про эту атаку вы можете прочитать в блоге. Брутить хеши на hashcat можно так:

git clone https://github.com/hashcat/hashcat && cd hashcat
git checkout 5236f3bd7 && make
./hashcat -m31300

Для атаки Targeted Timeroasting был разработан PowerShell скрипт. Но сегодня я переписал атаку на Python и выложил у себя в репозитории: https://github.com/PShlyundin/TimeSync
Назвал инструмент TimeSync, потому что мне эта атака очень напомнила классический DcSync.
