My friend @mojeda_101 and I had the funny idea to leverage GPO item-level targeting for domain persistence.

🖼️ RegreSSHion — OpenSSH Unauthenticated RCE

The Qualys Threat Research Unit has discovered a Remote Unauthenticated Code Execution vulnerability in OpenSSH’s server (sshd) in glibc-based Linux systems. CVE assigned to this vulnerability is CVE-2024-6387.

The vulnerability, which is a signal handler race condition in OpenSSH’s server (sshd), allows unauthenticated remote code execution (RCE) as root on glibc-based Linux systems.

New tool drop! 🔥🔥 de-optimizer uses several mathematical approaches for mutating machine code instructions to their functional equivalents. Very good for bypassing rule-based detection without using any RWE memory.

Recently, I wanted to quickly test some sleep obfuscation ideas against @jdu2600's EtwTi-FluctuationMonitor using Beacon, without dealing with UDRL debugging. At the end of the journey, I ended up with:

- A way to generate and load, via a PE loader, a UDRL-less Beacon payload.

- A way to generate and load, via a PE loader, a UDRL-less Beacon payload.
- A generic PE loader to hook Sleep and quickly prototype evasion ideas.
- Two different (though not necessarily novel) sleep obfuscation techniques, which allowed me to evade EtwTi-FluctuationMonitor and other scanners.

I dubbed these techniques MemoryBouncing and MemoryHopping. They both involve moving to another area of memory at every sleep and/or freeing the PE memory.

Here’s the blog post:

And the PE loader used, dubbed Dojoloader:

In his BH Asia presentation, @jdu2600 gave some hints on how the RX->RW detection could be bypassed. It sounded fun to test, and it was indeed a fascinating challenge for me. A huge thanks to him and his tools for sparking my curiosity.

Cool finding from my colleague @cj_berlin detailed here: . PS remoting and SSH ignores "Deny Logon restrictions". So if you enable SSHd on a Domain Controller, every domain user can log in... and, for example, perform a #RemotePotato0 attack 😲

Когда-то давно мы с моим хорошим другом @DrunkF0x на пентесте опробовали скрипт LDAPmonitor (как раз тогда он только вышел) - на тот момент все, что он делал, это "(objectClass=*)" на все объекты каждые N секунд и сравнивал результаты. Разумеется, это было жутко неэффективно, создает кучу трафика в эфире, а на больших доменах я бы вообще не рискнул запускать… Тогда у Ромы и появилась идея опроса изменений по значениям USN (Update Sequence Number), на основе которой им был разработан ADSpider 🕷️
Поздравляю с релизом!
