Root-cause analysis of a DDoS·breach and a rebuilt defense system

Pinned down the root cause of DDoS·hacking attempts and rebuilt the defense, from detection through response.

THE CHALLENGE

Why it was hard.

Repeated DDoS and intrusion attempts shook the service, but the team kept blocking ad hoc without pinning down the cause. Defense was scattered, so the same attack came back in a new shape. They needed a system, not one-off blocks.

Constraints

  • Respond live — keep availability
  • Root cause first
  • A standing system that prevents recurrence
OUR APPROACH

What we did.

  1. Incident analysisTrace logs, traffic, and intrusion paths to the root cause
  2. Defense designWAF, rate limiting, network boundaries, least privilege
  3. Automated detection·responseAnomaly detection with automatic blocking and alerts
  4. Standing operationsDrills and regular reviews keep the system sharp
OUTCOME

Outcome.

Ad hoc blocking became a standing defense that starts from root cause. We built boundaries and detection so the same attack can't recur, and it has run incident-free since — detecting and responding to attacks 24/7.
