Simulation

Test your last line of defense against encryption and data exfiltration — the final phases of a devastating attack.

Encryption and data exfiltration detection is the very last layer of defense to prevent disaster. If this layer fails, everything else was for nothing.

Last Line of Defense

Encryption Bypass

Testing endpoint protection ability to detect and halt file encryption operations before significant data loss occurs.

Living Off the Land

Utilizing legitimate system tools to stage and execute ransomware operations while evading signature-based detection.

Obfuscated C2

Establishing encrypted exfiltration channels that blend with legitimate traffic to test egress monitoring capabilities.

Ransomware Encryption

Deploying various encryption techniques used by modern ransomware groups to validate detection and response speeds.

Data Exfiltration Methods

Using multiple exfiltration techniques including DNS tunneling, HTTPS staging, and cloud service abuse to move data out.

Data Discovery & Staging

Identifying and cataloging sensitive data assets, then staging them for exfiltration to test data loss prevention controls.
