Кросс-сессионная активация или захватываем сессию пользователя без RemotePotato0, TGSThief, mimikatz и Process Injection! Давным-давно я писал о способе злоупотребления интерфейсом IHxHelpPaneServer. Однако вы когда в последний раз использовали моникеры? И я давным-давно... Поэтому нужно было найти альтернативный способ исполнения кода в сессии другого пользователя, забыв про все техники внедрения. Если посмотреть на код RemotePotato0 или RemoteKrbRelay , то можно заметить использование недокументированных интерфейсов ISpecialSystemProperties и IStandartActivator. Причем не сказать, что их использование довольно редкое. Их можно встретить в любой программе, которая позволяет стащить учётные данные (имеет переключатель -session). Сами по себе, они позволяют контролировать сессию, в которой создавать COM-объект. Ранее мы ловили от них только аутентификацию, но что мешает соединить использование этих интерфейсов с описанным в SeMishaPrivilege COM-классом IHxHelpPaneServer? Конечно же ничего! И я написал небольшой POC, который выложил на GitHub . Если вам интересно подробно окунуться в принцип работы инструмента, то советую обратить внимание на нашу статью на medium :)

😈 dirDevil: Hiding Code and Content Within Folder Structures This article describes a method for hiding data within directory structures by using GUIDs in folder names to encode information. This approach bypasses antivirus and DLP systems since the data is stored in folder names rather than files, making it difficult to detect and analyze. 🔗 Research: https://trustedsec.com/blog/dirdevil-hiding-code-and-content-within-folder-structures 🔗 Source: https://github.com/nyxgeek/dirdevil #hide #code #folder #evasion

🪞 Smoke and Mirrors — Driver Signatures Are Optional ItsNotASecurityBoundary is an exploit that leverages False File Immutability assumptions in Windows Code Integrity (ci.dll) to trick it into accepting an improperly-signed security catalog containing fraudulent authentihashes. With attacker-controlled authentihashes loaded and trusted by CI, the kernel will load any driver of the attacker's choosing, even unsigned ones. 🔗 https://github.com/gabriellandau/ItsNotASecurityBoundary #driver #signature #bypass #ffi #windows

💻 TREVORproxy This is a simple SOCKS proxy that helps avoid Smart Lockout by load-balancing your requests between multiple IP addresses. It accomplishes this with built-in Linux features -- no complex OpenVPN setups or strange firewall configurations. There are two techniques that TREVORproxy can use to spread your requests across multiple IP addresses: an SSH Proxy and a Subnet Proxy. — SSH Proxy You give TREVORproxy some hosts that support SSH, and it sends your traffic through them, making sure to balance equally between all the hosts. — Subnet Proxy If you have access to a /64 IPv6 subnet (Linode is perfect for this), TREVORproxy will load-balance your requests across eighteen quintillion (18,446,744,073,709,551,616) unique source addresses. 🔗 Source: https://github.com/blacklanternsecurity/TREVORproxy #ip #rotation #waf #bypass
