Top Three Linux Enumeration Tools (2024)
PSPY
PSPY is a tool which allows obtaining processes information without having root privileges.

Sensitive information can be obtained only with permissions. This helps to get root access on numerous systems.
How PSPY works?
Pspy obtains the information of the processes in procfs (Linux process files system). The inotify API is used, which does not need root permissions. With this API, we can get notifications when a file is created, altered or deleted. Pspy monitors with the notify
API the contents of the system /proc folder to try to capture the processes that are created.
Some useful commands are,
● –help: To see all the flags present and their definition
● -p: Enables printing commands to stdout.
● -f: Enables printing file system events to stdout.
● -r: List of directories to watch with Inotify. pspy will watch all subdirectories recursively (by default, watches /usr, /tmp, /etc, /home, /var, and /opt).
● –debug: Prints verbose error messages which are otherwise hidden.
