Testing Your Defences Against Encryption-Based Attacks

Service Overview

Ransomware remains one of the most disruptive and costly cyber threats organisations face today. Adversaries continuously refine their tactics, combining data exfiltration, targeted encryption, and multi-stage extortion techniques.

SilentGrid’s Ransomware Simulation leverages custom-built ransomware to safely replicate the encryption of local folders, network shares, and critical paths, simulating the full lifecycle of modern ransomware attacks. This controlled simulation provides critical insights into how your detection, response, and containment strategies perform under realistic attack conditions – without risking production environments.

Why Simulate Ransomware Attacks?

The Evolving Ransomware Threat

• Double Extortion – Attackers encrypt data while also exfiltrating sensitive information for additional leverage.
• Targeted Campaigns – Modern ransomware gangs conduct thorough reconnaissance to target high-value assets.
• Rapid Impact – Ransomware spreads laterally across networks, encrypting critical data in minutes if undetected.

Ransomware simulations expose weaknesses in endpoint security, SIEM alerting, EDR configurations, and response workflows, enabling your organisation to fortify defences before real attacks occur.

SilentGrid’s Ransomware Simulation Approach

SilentGrid uses internally developed ransomware that mimics the behaviour of real-world payloads, encrypting folders and files across local and networked environments. This allows us to test your security stack’s effectiveness at every stage of a ransomware attack – from initial execution to payload deployment and containment.

Key Characteristics of Our Custom Ransomware:

• Safe Execution – Designed to safely encrypt files without destructive impact. Files are restorable post-simulation.
• Controlled Environment – Simulations are executed in sandbox environments, isolated networks, or dedicated testing systems.
• Local and Network Testing – Encrypts files on local machines, remote shares, and critical infrastructure paths to simulate lateral spread.
• Payload Flexibility – Tailored to match your environment, allowing us to test different payload delivery mechanisms.

Deliverables and Reporting

SilentGrid provides comprehensive reports outlining:

• Detection and Response Gaps – Identification of missed detections, slow responses, and containment delays.
• Endpoint Security Evaluation – Assessing the performance of EDR, antivirus, and file integrity monitoring tools.
• Incident Response Recommendations – Tactical guidance on improving ransomware readiness and remediation workflows.
• Executive Summary – High-level overview for leadership, detailing potential business impacts and strategic risk mitigations.

Benefits of Ransomware Simulation

• Test Real-World Scenarios
  Experience ransomware attacks safely and realistically in controlled environments.

• Identify Detection Gaps
  Uncover blind spots in EDR, SIEM, and incident response processes.

• Strengthen Containment Protocols
  Assess your organisation’s ability to contain ransomware spread across endpoints and networks.

• Improve Response Readiness
  Equip SOC and IR teams with real-world experience in managing ransomware incidents.

Is Ransomware Simulation Right for You?

Ransomware simulation is ideal for organisations that:

• Manage high-value data or operate in targeted industries (finance, healthcare, critical infrastructure).
• Have SIEM, EDR, and incident response processes that need validation.
• Want to test network segmentation and endpoint protections against encryption-based threats.
• Require hands-on experience to train SOC analysts and response teams.
