The Problem of Ransomware
How does ransomware propagate?
Ransomware attacks follow a very predictable method of spreading across hybrid IT once they have successfully entered an organization. Two of the key tactics employed in this process are “Network and Domain Discovery” and “Lateral Movement”:
MITRE ATT&CK® Tactics Essential to Ransomware
Network Discovery helps the attacker build a better understanding of the target environment – what exists, how are they interconnected, what is accessible.
Stop this and the attacker has less useful information about the victim’s network – the net effect is that they are either limited in the progress they can make or are forced to change their tactics to gather the same information, increasing the chances of detection.
Lateral Movement enables the attacker to move to the next target or intermediary victim.
Stop this and the attack cannot progress any further, significantly reducing the number of compromised resources.
Limiting or preventing Network Discovery and Lateral Movement severely hampers the progress of the attack. However doing this successfully has been a challenge for organizations due to:
- Poor visibility
A lack of visibility makes it difficult to identify potential weak points in the system, and monitor the movements of the attacker
- Too many open ports
Commonly used ports left open create pathways for ransomware to quickly spread and take over the organization
- A lack of proactive security defenses
Relying solely on detection-based solutions has shown to be too slow in stopping an attack
