Put your snort skills into practice and defend against a live attack. The room invites you to a challenge where you will investigate a series of traffic data and stop malicious activity under two different scenarios. Let’s start working with Snort to analyse live and captured traffic.
Before joining this room, we suggest completing the Snort room.
Note: There are two VMs attached to this challenge. Each task has dedicated VMs. You don’t need SSH or RDP, the room provides a “Screen Split” feature.
// 01 Task 2 Scenario 1 | Brute-Force
Use the attached VM to finish this task.

Sir, you need to observe the traffic with Snort and identify the anomaly first. Then you can create a rule to stop the brute-force attack. GOOD LUCK!
First of all, start Snort in sniffer mode and try to figure out the attack source, service and port.
Then, write an IPS rule and run Snort in IPS mode to stop the brute-force attack. Once you stop the attack properly, you will have the flag on the desktop!
Here are a few points to remember:
- Create the rule and test it with “-A console” mode.
- Use “-A full” mode and the default log path to stop the attack.
- Write the correct rule and run the Snort in IPS “-A full” mode.
- Block the traffic at least for a minute and then the flag file will appear on your desktop.
Question: Stop the attack and get the flag (which will appear on your Desktop)

Question: What is the name of the service under attack?
Answer: SSH
Question: What is the used protocol/port in the attack?
