Deep Blue is one of the most straightforward challenges in the Blue Teams Labs. It focuses on understanding Windows Event codes and analyzing command history. Throughout this challenge, I learned how to identify Meterpreter, a tool that allows attackers to control a victim’s computer by running an invisible shell and establishing a reverse communication channel.

The key to success is patience, careful analysis, and asking critical questions. For example: “Should a software update be located in a user’s downloads folder?” This type of thinking is essential for detecting suspicious activity.
