Testing Locked-Down Environment Security

Restricted environments—such as virtual desktops, kiosks, and embedded terminals—are designed to enforce user limitations and prevent unauthorised access to underlying systems. However, misconfigurations, software vulnerabilities, and insecure design often allow attackers to escape these environments, escalate privileges, and gain access to sensitive resources.

SilentGrid's Restricted Environment Breakout Testing simulates real-world attacks against virtual desktops, kiosk terminals, embedded systems, and locked-down environments to uncover vulnerabilities that could lead to breakouts, data exposure, or network compromise.

Methodology

SilentGrid's breakout testing methodology leverages real-world adversarial tactics and technical experience of our senior consultants.

Environment Reconnaissance

• Mapping and enumerating restrictions, configurations, and sandbox policies
• Identifying hidden functionality and exposed file systems

Breakout Attempt and Exploitation

• Simulating command injection, script execution, and interface bypass attacks
• Testing for vulnerabilities in underlying hypervisors, kiosk software, or desktop environments

Privilege Escalation and Lateral Movement

• Assessing pathways for post-breakout privilege escalation
• Testing for segmentation flaws that allow attackers to pivot into sensitive networks

Persistence Testing

• Evaluating methods for gaining persistence within compromised environments
• Testing breakout methods that persist through reboots or session resets

Deliverables

SilentGrid's restricted environment assessments provide detailed insights for strengthening controls and preventing unauthorised breakouts.

Why Restricted Environment Security Matters

Breakouts from locked-down environments can lead to:

✓ Access to internal networks and sensitive systems
✓ Privilege escalation, data exfiltration, and network reconnaissance
✓ Unauthorised administrative access through overlooked misconfigurations
