🕳 Ngrok: SSH Reverse Tunnel Agent

Did you know that you can run ngrok without even installing ngrok? You can start tunnels via SSH without downloading an ngrok agent by running an SSH reverse tunnel command:

ssh -i ~/.ssh/id_ed25519 -R 80:localhost:80 [email protected] http

I've found that fibers may be something to look at when it comes to execute local in-memory code. This is a simple PoC of how you can leverage fibers to execute in-memory code without spawning threads and hiding suspicious thread stacks among others.

ETWHash

ETWHash is a C# POC that is able to extract NetNTLMv2 hashes of incoming authentications via SMB, by consuming ETW events from the Microsoft-Windows-SMBServer provider {D48CE617-33A2-4BC3-A5C7-11AA4F29619E}

🥶 Freeze

Freeze.rs is a payload creation tool used for circumventing EDR security controls to execute shellcode in a stealthy manner. Freeze.rs utilizes multiple techniques to not only remove Userland EDR hooks, but to also execute shellcode in such a way that it circumvents other endpoint monitoring controls.

This is a reverse/back-connect SOCKS5 proxy tunnel that can be used to route traffic through a system that can't be directly accessed (e.g. due to NAT). The channel is secured by mutually trusted TLS with auto-generated certificates based on a connection key.

CVE-2023-32233 LPE

In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled.

Once the PoC is started on a vulnerable system, it may leave that system in an unstable state with corrupted kernel memory. We strongly recommend to test the PoC on a dedicated system to avoid potential data corruptions.

🔀 Direct Syscalls vs Indirect Syscalls

This post discusses Indirect Syscalls as a solution to eliminate indicators of compromise and avoid detection by EDRs. Indirect Syscalls allow the execution of Syscall and Return statements in the memory of ntdll.dll, which is the usual behavior in Windows.

We took a Cobalt Strike profile, modified it, and bypassed Crowdstrike & Sophos without encrypting the shellcode. Also bypassed all published YARA rules, sleep detections, and string detections around a CS beacon.

🎯 GitLab CE/EE Path Traversal Vulnerability (CVE-2023-2825)

On May 23, 2023, GitLab released version 16.0.1, which addressed a critical vulnerability, CVE-2023-2825, impacting both the Community Edition (CE) and Enterprise Edition (EE) version 16.0.0. This vulnerability enables unauthenticated users to read arbitrary files by exploiting a path traversal bug. Additionally, an unauthenticated malicious user can leverage a path traversal vulnerability to read arbitrary files on the server if there is an attachment present in a public project nested within a minimum of five groups.
