Unpacking a post-compromise breach simulation with Vector Command

The reality of modern cyber threats

In today’s evolving cyber landscape, breaches are not a matter of if, but when. Attackers continue to refine their techniques, using stealthy post-compromise tactics to maintain persistence, escalate privileges, and move laterally across networks. The key to staying ahead is not just preventing attacks, but building resilience to withstand and respond to them effectively.

This concept of resilience aligns with Continuous Threat Exposure Management (CTEM), a proactive approach to security validation. According to Gartner, CTEM consists of five pillars:

When we look at the five pillars, described by Gartner:

Scope of your organization’s attack surface;Discover your attack surface;Prioritize your vulnerabilities;Validate security controls and finally;Mobilize people and processes to operationalize the CTEM findings.

Vector Command plays a critical role in the fourth pillar, continuously testing security defenses through post-compromise breach simulations that replicate real-world adversary tactics.

How Vector Command tests resilience

This blog is the third in our Vector Command series, where we explore the tactics, techniques, and procedures (TTPs) leveraged by Rapid7’s expert red team. Today, we’re focusing on post-compromise breach simulations—a critical capability in assessing an organization’s ability to detect and respond to a persistent adversary.

TTP mapping to the MITRE ATT&CK framework

Once an attacker gains access—whether through phishing or external exploitation—the real damage begins. As part of our post-compromise breach simulation, Vector Command emulates the tactics and techniques adversaries use once they’re inside, leveraging the MITRE ATT&CK® frameworks ..
