AZURE AD CLIENT SECRET LEAK: THE KEYS TO CLOUD

Summary from the TLDR InfoSec newsletter

Exposing Azure AD credentials in public configuration files (like appsettings.json) gives attackers direct access to cloud resources because with these secrets, attackers can impersonate trusted apps, exfiltrate data, escalate privileges, and persist within an organization. Leaks occur due to misconfiguration, poor secrets management, and insufficient security checks. To prevent this, restrict access, move secrets out of code, rotate exposed keys immediately, use least privilege, and monitor for misuse to prevent severe breaches.
