Admin Login Attack Detection

What This Means

Detect attacks targeting administrative accounts. Monitor privileged account authentication for brute force, credential stuffing, and unauthorized access attempts against admin interfaces.

Example Log

-- Multiple platforms showing admin account targeting:
[IIS]     POST /admin/login 401 from 185.220.101.42 (user: admin)
[Windows] Event 4625: Administrator failed from 185.220.101.42 Type 10
[SSH]     Failed password for root from 185.220.101.42
[Web]     POST /wp-admin/admin-ajax.php 401 from 185.220.101.42

Indicators of Suspicious Activity

• Concentrated attacks on accounts named admin, administrator, root, sa, dba
• Attacks targeting known admin endpoints (/admin, /wp-admin, /administrator, /manager)
• Login attempts using default credentials for common platforms
• Simultaneous admin attacks across multiple services from one IP
• Admin authentication from non-admin workstations or non-PAW systems
• Successful admin login from unrecognized IP or location

How to Investigate

1. Identify all admin accounts being targeted across all platforms
2. Verify that no admin accounts still use default passwords
3. Check if any targeted admin accounts successfully authenticated from attack IPs
4. Review admin endpoint exposure — which admin panels are internet-accessible
5. Assess whether admin accounts have MFA enforced consistently
6. Check for admin account creation or privilege escalation around the attack time

Recommended Mitigations

• Rename or disable default admin accounts (Administrator, root, sa)
• Restrict admin login pages to internal networks or VPN-only access
• Enforce MFA on all administrative accounts without exception
• Implement Privileged Access Workstations (PAWs) for admin tasks
• Deploy honeypot admin pages that alert on any login attempt
• Require Just-In-Time admin access with time-limited elevation
