LsassReflectDumping – A Deep Dive Into Secure Credential Extraction Techniques

This tool leverages the Process Forking technique using the RtlCreateProcessReflection API to clone the lsass.exe process.

Once the clone is created, it utilizes MINIDUMP_CALLBACK_INFORMATION callbacks to generate a memory dump of the cloned process.

Steps

• Getting the handle of Lsass.exe process
• Cloning Lsass.exe process using RtlCreateProcessReflection (Process Forking)
• Using MINIDUMP_CALLBACK_INFORMATION callbacks to create cloned process minidump
• Confirming the dump content and size.
• Terminating the cloned process.

Usage

Simply execute the compiled file.

ReflectDump.exe 

Offline Dumping

Use Mimikatz or Pypykatz to parse the dump file offline.

sekurlsa::minidump [filename] sekurlsa::logonpasswords
pypykatz lsa minidump [filename]

Upcoming Features

* Encrypt dump before writing on disk to bypass static detection.
* Exfiltrate on C2 Server
