⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could enumerate all valid user accounts, enabling targeted credential attacks, social engineering, or account takeover attempts against the entire user base.

🟠

Likely Case

Attackers will gather partial user account information through error message analysis, facilitating targeted attacks against discovered accounts.

🟢

If Mitigated

📡 Detection & Monitoring

Log Indicators:

  • Unusual volume of failed login attempts
  • Patterns of sequential username/account testing
  • Requests to authentication endpoints with varying usernames

Network Indicators:

  • High volume of requests to login/authentication endpoints from single IPs
  • Patterns suggesting automated account enumeration

SIEM Query:

source="vira-investing-logs" AND (event_type="authentication_failure" OR event_type="login_attempt") | stats count by src_ip, username | where count > threshold
