When a zero-day exploit targets your infrastructure, the clock starts ticking. Fast. And in today’s threat landscape, speed without context is chaos. That’s why more security teams are turning to Managed Detection and Response (MDR) to bridge the gap between alert and action.
But what does effective MDR look like during a live, fast-moving attack?
In our latest eBook, The First 24 Hours of a Cyberattack, we break down how Rapid7 MDR responded to a real-world threat – CVE-2025-53770 — before it could spread. You’ll see how detection, investigation, and containment unfolded in near real time, and what it takes to stay in control when the timeline is measured in minutes.
What really happens when an exploit hits?
Most incident timelines start when an alert is received. But by then, attackers may already be moving laterally, stealing credentials, or setting up persistence. Rapid7 MDR detected the SharePoint exploit within minutes of deployment, triaged the encoded PowerShell command, and escalated the threat before any sensitive data was exposed.
The key? Context-rich detection powered by agentic AI, combined with 24/7 expert response and real-time containment. No noise. No delay. No uncertainty.
What this means for security teams
Even the best internal SOCs are overwhelmed. High volumes of low-context alerts, complex hybrid environments, and constant pressure to prove ROI make it harder to focus on what matters. This eBook gives you a front-row seat to:
-
What makes a signal stand out from the noise
-
How a named analyst team and unlimited IR change the game
-
Why automated triage must be backed by human insight
-
What clear reporting and guided recovery actually look like
MDR in action
Outnumbered. Never outmatched.
This isn’t a hypothetical walkthrough. It’s a breakdown of what really happened when Rapid7 MDR faced a widespread, fast-moving exploit in the wild. You’ll see:
-
How the attacker was identified in seconds, not hours
-
What tools, processes, and people helped stop lateral movement
-
Where visibility, threat intel, and Active Response came together to contain the incident
