Cyber attacks via MDR

When a zero-day exploit strikes, every minute counts. But speed without context leads to chaos. That’s why many security teams rely on Managed Detection and Response (MDR) to bridge the gap between alert and response.

In the e-book “The First 24 Hours of a Cyber Attack,” we show how Rapid7 MDR detected and stopped a real threat – CVE-2025-53770 – before it could spread. Detection, investigation and containment were performed in near real time, supported by agent-based AI and 24/7 expert response.

The key: context-rich detection, clear escalation, and immediate containment. Rapid7 MDR detected the SharePoint exploit within minutes, triaged encrypted PowerShell commands, and blocked the threat before any data was compromised.

The e-book shows how signals are distinguished from noise, why unlimited incident response is crucial, how humans and AI interact, and what clear reporting and guided recovery look like.

This is not a theoretical scenario, but a real attack and a lesson in how MDR provides security teams with clarity, confidence and control.
