Digital forensics

We suspect that one of our machines has been compromised. We need to investigate the incident to gather more information.

Question 1: What was the name of the script that ran on the machine?

Question 2: Which service was used to connect the machine to other devices?

Question 3: What IP address did the machine try to connect to?

Question 4: We think the script hidden a command to be executed later. Can you find that command?

Question 5: What does make a secure system? You could get an answer from our Team!
