With my new blog post "Direct Syscalls: A journey from high to low" I try to explain what a syscall is, what a direct syscall is, why an attacker (red team) uses it, etc.
I also try to explain how to build and understand your own shellcode dropper step by step, starting with high level APIs and ending with direct syscalls (low level APIs).

The code samples to play with in your own LAB are also available in my github repository.

О дампе реестра с помощью SecretsDump и Co.
Долгое время я не знал, что, оказывается, secretsdump[.]py не только читает и расшифровывает ветки SAM и SECURITY прямиком из удаленного реестра, но также и экспортирует их на диск в файлы
В случаях, когда нужно спарсить LSA прямиком с Windows-хоста, я любил пользоваться SharpSecDump (который тоже сохраняет ветки на диск в файлы
После прочтения недавнего поста от @Synacktiv я узнал о крутой тулзе SharpSecretsdump, которая (по беглому просмотру) не дампает хивы в файлы и, соответственно, оставляет меньше IOC-ов от своего использования. Рекомендую обновить арсенал всем заинтересованным 😉
Долгое время я не знал, что, оказывается, secretsdump[.]py не только читает и расшифровывает ветки SAM и SECURITY прямиком из удаленного реестра, но также и экспортирует их на диск в файлы
%SYSTEMROOT%\Temp\*.tmp для извлечения отдельных значений, которые не получается достать "на горячую" (скриншот 1). Приостановив выполнение скрипта, их можно скачать и убедиться в этом самостоятельно (скриншот 2).В случаях, когда нужно спарсить LSA прямиком с Windows-хоста, я любил пользоваться SharpSecDump (который тоже сохраняет ветки на диск в файлы
%SYSTEMROOT%\*.log) с флагом -target=127.0.0.1, однако после того, как умные люди (@bugch3ck) заметили, что права доступа на экспортированные ветки позволяют низкопривилегированным пользакам их прочитать, стал относиться к ее использованию более аккуратно. Это происходит из-за наследования прав на создаваемые файлы в директории C:\Windows\ (скриншоты 3, 4).После прочтения недавнего поста от @Synacktiv я узнал о крутой тулзе SharpSecretsdump, которая (по беглому просмотру) не дампает хивы в файлы и, соответственно, оставляет меньше IOC-ов от своего использования.
