Detecting Password-Spraying in Entra ID Using a Honeypot Account
Category:Industry News / Research & Tools
TrustedSec details a practical detection pattern for Entra ID password spraying using a decoy/honeypot account. The method leverages sign‑in error codes and IP telemetry to distinguish real user mistakes from automated sprays, reducing false positives in cloud identity environments.
CORTEX Protocol Intelligence Assessment
Business Impact: Enhanced detection improves mean‑time‑to‑detect for credential attacks on cloud identities. Technical Context: Uses Entra sign‑in logs (e.g., 50126, 50079) and decoy account activity for signal fidelity.
Strategic Intelligence Guidance
- Create decoy users with monitored sign‑in logs.
- Alert on repeated failures against decoys.
- Correlate spray activity by IP, app, and geo.
- Automate blocking and step‑up auth on detection.
