Explanation
The log files show that the attacker was able to access files and directories that were not intended to be accessible by web users, such as "/etc/passwd" and "/var/log". This indicates that the attacker was able to exploit a vulnerability in the web server or application that allowed them to manipulate the file path and access arbitrary files on the server. This is a type of attack known as directory traversal, which can lead to information disclosure, privilege escalation, or remote code execution3.
