Conti Move To Remote System

Using the Jambi agent from the previous chain, discover targets on the Active Directory and then perform targeted lateral movement of the Jambi agent by first moving the agent to the desired target and then starting the agent.

TTP Tuesday: Conti (Release 4)

Move to remote systems

Theme Overview

We're releasing the fourth installment of our Conti ransomware theme with new TTPs focused on Windows lateral-movement using live off the land techniques. To date, our Conti theme now contains the following kill-chains:

1. Recon and Initial Access
2. Local and Remote Discovery
3. Gain privileges and persist
4. Move to remote systems (Current Release)
5. Data collection and exfiltration
6. Deploy ransomware

Move To Remote Systems

This chain performs lateral movement within the domain. First, we check for all hosts on the domain. After selecting a target, we then enable access to the target's storage resources. We then move the agent executable from our current host to the target host. Finally, we execute the agent on the target host performing lateral movement within the domain. This chain does have a user custom fact for the target host information which you can provide in the facts section, or you can modify the TTP itself removing `#{target.host}` and providing the information manually.
