Full Disk Encryption w/ TPM2 on Kali

Short HOWTO about setting up Full Disk Encryption with unattended auto-unlock using TPM2 on Kali.

Useful for rogue devices (auto-connecting to C2), headless pentest boxes, etc. storing confidential information but lacking physical security.

NOTE: In order to maintain integrity and protect the encryption key, hardening the boot process with Secure Boot is a must. For making Secure Boot work (without messing up the default UEFI keys stored in the hardware), the Microsoft-signed UEFI shim loader is used (available in the Kali repo) which is able to load securely an arbitrary ELF image as 2nd stage

log4j RCE Exploitation Detection

You can use these commands and rules to search for exploitation attempts against log4j RCE vulnerability CVE-2021-44228

Grep / Zgrep

This command searches for exploitation attempts in uncompressed files in folder /var/log and all sub folders

sudo egrep -I -i -r '\$(\{|%7B)jndi:(ldap[s]?|rmi|dns|nis|iiop|corba|nds|http):/[^\n]+' /var/log

Overview

In the default configuration of Active Directory, it is possible to remotely take over Workstations (Windows 7/10/11) and possibly servers (if Desktop Experience is installed) when their WebClient service is running. This is accomplished in short by;

• Triggering machine authentication over HTTP via either MS-RPRN or MS-EFSRPC (as demonstrated by @tifkin_). This requires a set of credentials for the RPC call.
• Relaying that machine authentication to LDAPS for configuring RBCD
• RBCD takeover

The caveat to this is that the WebClient service does not automatically start at boot. However, if the WebClient service has been triggered to start on a workstation (for example, via some SharePoint interactions), you can remotely take over that system. In addition, there are several ways to coerce the WebClient service to start remotely which I cover in a section below.
