PowerMemory: Exploit the Credentials present in Files and Memory

PowerMemory is a PowerShell post-exploitation tool. It uses Microsoft binaries and therefore is able to execute on a machine, even after the Device Guard Policies have been set. In the same way, it will bypass antivirus detection. PowerMemory can retrieve credentials information and manipulate memory. It can execute shellcode and modify process in memory (in userland and kernel land as a rootkit). PowerMemory will access everywhere in user-land and kernel-land by using the trusted Microsoft debugger aka cdb.exe which is digitally signed. PoweMemory was tested on 2003, 2008r2, 2012, 2012r2 and Windows 7 – 32 and 64 bits, Windows 8 and Windows 10 Home edition.

Features:
  • fully PowerShell
  • it can work locally, remotely or from a dump file collected on a machine
  • it does not use the operating system .dll to locate credentials address in memory but a simple Microsoft debugger
  • it does not use the operating system .dll to decypher passwords collected –> it is does in the PowerShell (AES, TripleDES, DES-X)
  • it breaks undocumented Microsoft DES-X
  • it works even if you are on a different architecture than the target
  • it leaves no trace in memory less

Magic Unicorn is a simple tool for using a PowerShell downgrade attack and inject shellcode straight into memory. Based on Matthew Graeber’s powershell attacks and the powershell bypass technique presented by David Kennedy (TrustedSec) and Josh Kelly at Defcon 18. Usage is simple, just run Magic Unicorn (ensure Metasploit is installed and in the right path) and magic unicorn will automatically generate a powershell command that you need to simply cut and paste the powershell code into a command line window or through a payload delivery system.Unicorn is a PowerShell injection tool utilizing Matthew Graebers attack and expanded to automatically downgrade the process if a 64 bit platform is detected. This is useful in order to ensure that we can deliver a payload with just one set of shellcode instructions. This will work on any version of Windows with PowerShell installed
