Theme Overview

8 February 2022

We're releasing the fifth release of our Conti ransomware theme with new TTPs focused on data collection and exfiltration. To date, our Conti theme now contains the following kill-chains:

Recon and Initial Access
Local and Remote Discovery
Gain privileges and persist
Move to remote systems
Data collection and exfiltration (Current Release)
Deploy ransomware

Data Collection and Exfiltration

This chain performs collection and exfiltration. First we enumerate the users home directory then attempt to dump hashes via Kerberoasting and AS-REProasting. Once we have target data, the ingress and configure Rclone to work with an ephemeral Mega account then automatically exfiltrate to a Data folder in Mega. Check it out on the Prelude chains website.

Watch a demonstration:

We have 1 more week to go in our Conti theme providing you with an entire Conti adversary attack from beginning to end.
