Privilege Escalation

Hardware-based Privilege Escalation

  • Writeups
  • Tools
    • Inception
      • Inception is a physical memory manipulation and hacking tool exploiting PCI-based DMA. The tool can attack over FireWire, Thunderbolt, ExpressCard, PC Card and any other PCI/PCIe HW interfaces.
    • PCILeech
      • PCILeech uses PCIe hardware devices to read and write from the target system memory. This is achieved by using DMA over PCIe. No drivers are needed on the target system.
    • physmem
      • physmem is a physical memory inspection tool and local privilege escalation targeting macOS up through 10.12.1. It exploits either CVE-2016-1825 or CVE-2016-7617 depending on the deployment target. These two vulnerabilities are nearly identical, and exploitation can be done exactly the same. They were patched in OS X El Capitan 10.11.5 and macOS Sierra 10.12.2, respectively.

  • Command and Control
    • Empire
      • Empire is a post-exploitation framework that includes a pure-PowerShell2.0 Windows agent, and a pure Python 2.6/2.7 Linux/OS X agent. It is the merge of the previous PowerShell Empire and Python EmPyre projects. The framework offers cryptologically-secure communications and a flexible architecture. On the PowerShell side, Empire implements the ability to run PowerShell agents without needing powershell.exe, rapidly deployable post-exploitation modules ranging from key loggers to Mimikatz, and adaptable communications to evade network detection, all wrapped up in a usability-focused framework. PowerShell Empire premiered at BSidesLV in 2015 and Python EmPyre premeiered at HackMiami 2016.
    • Koadic
      • Koadic, or COM Command & Control, is a Windows post-exploitation rootkit similar to other penetration testing tools such as Meterpreter and Powershell Empire. The major difference is that Koadic does most of its operations using Windows Script Host (a.k.a. JScript/VBScript), with compatibility in the core to support a default installation of Windows 2000 with no service packs (and potentially even versions of NT4) all the way through Windows 10.

SessionGopher works by querying the HKEY_USERS hive for all users who have logged onto a domain-joined box at some point. It extracts PuTTY, WinSCP, SuperPuTTY, FileZilla, and RDP saved session information. It automatically extracts and decrypts WinSCP, FileZilla, and SuperPuTTY saved passwords. When run in Thorough mode, it also searches all drives for PuTTY private key files (.ppk) and extracts all relevant private key information, including the key itself, as well as for Remote Desktop (.rdp) and RSA (.sdtid) files.

        • Kerberos Credential Thiever (GNU/Linux) - Ronan Loftus, Arne Zismer
          • Kerberos is an authentication protocol that aims to reduce the amount of sensitive data that needs to be sent across a network with lots of network resources that require authentication. This reduces the risk of having authentication data stolen by an attacker. Network Attached Storage devices, big data processing applications like Hadoop, databases and web servers commonly run on GNU/Linux machines that are integrated in a Kerberos system. Due to the sensitivity of the data these services deal with, their security is of great importance. There has been done a lot of research about sniffing and replaying Kerberos credentials from the network. However, little work has been done on stealing credentials from Kerberos clients on GNU/Linux. We therefore investigate the feasibility of extracting and reusing Kerberos credentials from GNU/Linux machines. In this research we show that all the credentials can be extracted, independently of how they are stored on the client. We also show how these credentials can be reused to impersonate the compromised client. In order to improve the security of Kerberos, we also propose mitigations to these attacks.

        • 3snake
          • Targeting rooted servers, reads memory from sshd and sudo system calls that handle password based authentication. Doesn't write any memory to the traced processes. Spawns a new process for every sshd and sudo command that is run. Listens for the proc event using netlink sockets to get candidate processes to trace. When it receives an sshd or sudo process ptrace is attached and traces read and write system calls, extracting strings related to password based authentication.

Unlike many of the enumeration tools out there already, nullinux can enumerate multiple targets at once and when finished, creates a users.txt file of all users found on the host(s). This file is formatted for direct implementation and further exploitation.This program assumes Python 2.7, and the smbclient package is installed on the machine. Run the script to check if these packages are installed.

Armed with the bug, it was trivial to programmatically bypass Apple's touted 'User-Approved Kext' security feature, dump all passwords from the keychain, bypass 3rd-party security tools, and much more! And as Apple's patch was incomplete (surprise surprise) we'll drop an 0day that (still) allows unprivileged code to post synthetic events and bypass various security mechanisms on a fully patched macOS box!

      • Macs are becoming commonplace in corporate environments as a alternative to Windows systems. Developers, security teams, and executives alike favor the ease of use and full administrative control Macs provide. However, their systems are often joined to an active directory domain and ripe for attackers to leverage for initial access and lateral movement. Mac malware is evolving as Mac computers continue to grow in popularity. As a result, there is a need for proactive detection of attacks targeting MacOS systems in a enterprise environment. Despite advancements in MacOS security tooling for a single user/endpoint, little is known and discussed regarding detection at a enterprise level. This talk will discuss common tactics, techniques and procedures used by attackers on MacOS systems, as well as methods to detect adversary activity. We will take a look at known malware, mapping the techniques utilized to the MITRE ATT&CK framework. Attendees will leave equipped to begin hunting for evil lurking within their MacOS fleet.

    • You Can Type, but You Can’t Hide: A Stealthy GPU-based Keylogger
      • Keyloggers are a prominent class of malware that harvests sensitive data by recording any typed in information. Key- logger implementations strive to hide their presence using rootkit-like techniques to evade detection by antivirus and other system protections. In this paper, we present a new approach for implementing a stealthy keylogger: we explore the possibility of leveraging the graphics card as an alterna- tive environment for hosting the operation of a keylogger. The key idea behind our approach is to monitor the system’s keyboard buffer directly from the GPU via DMA, without any hooks or modifications in the kernel’s code and data structures besides the page table. The evaluation of our pro- totype implementation shows that a GPU-based keylogger can effectively record all user keystrokes, store them in the memory space of the GPU, and even analyze the recorded data in-place, with negligible runtime overhead.

Payloads can be retrieved using Web or DNS delivery or both; SharpShooter is compatible with the MDSec ActiveBreach PowerDNS project. Alternatively, stageless payloads with embedded shellcode execution can also be generated for the same scripting formats.

This is an evasion technique to get round content / file-type inspection implemented by some security-appliances. This tool is not designed to create awesome HTA content. There are many other tools/techniques that can help you with that. What it might help you with is getting your HTA into an environment in the first place, and (if you use environmental keying) to avoid it being sandboxed.

      • Invoke-PSImage
        • Invoke-PSImage takes a PowerShell script and embeds the bytes of the script into the pixels of a PNG image. It generates a oneliner for executing either from a file of from the web (when the -Web flag is passed). The least significant 4 bits of 2 color values in each pixel are used to hold the payload. Image quality will suffer as a result, but it still looks decent. The image is saved as a PNG, and can be losslessly compressed without affecting the ability to execute the payload as the data is stored in the colors themselves. It can accept most image types as input, but output will always be a PNG because it needs to be lossless. Each pixel of the image is used to hold one byte of script, so you will need an image with at least as many pixels as bytes in your script. This is fairly easy—for example, Invoke-Mimikatz fits into a 1920x1200 image.
