FLAG OVER
Daily AlpacaHackTopic: Environment VariableReleased: Mar 9, 2026
The Process Filesystem (procfs) is a virtual filesystem that allows process and kernel information to be accessed as files on systems such as Linux.
In CTFs, players aim to obtain the flag by reading information under /proc/self/ or /proc/<pid>/, such as the state of a running process, environment variables, and command-line arguments.
