Attackers are exploiting weak secrets hygiene, over-privileged accounts and flat networks faster than most teams can detect them. This guide walks you step-by-step through a realistic breach using the MITRE ATT&CK framework to expose the exact failure points that let adversaries escalate, pivot and exfiltrate your data. Learn how identity-first security, dynamic credentials and zero trust access patterns help teams close these vulnerabilities, reduce blast radius and build a more resilient security posture across cloud-native environments.
