Instructions:
Unzip the challenge (pass: cyberdefenders.org), examine the image, and answer the provided questions.
Case Overview:
The SOC team got an alert regarding some illegal port scanning activity coming from an employee's system. The employee was not authorized to do any port scanning or any offensive hacking activity within the network. The employee claimed that he had no idea about that, and it is probably a malware acting on his behalf. The IR team managed to respond immediately and take a full forensic image of the user's system to perform some investigations.
There is a theory that the user intentionally installed illegal applications to do port scanning and maybe other things. He was probably planning for something bigger, far beyond a port scanning!
It all began when the user asked for a salary raise that was rejected. After that, his behavior was abnormal and different. The suspect is believed to have weak technical skills, and there might be an outsider helping him!
Your objective as a soc analyst is to analyze the image and to either confirm or deny this theory.
