fstab
fstab (file systems table) is a configuration file commonly found in the directory /etc in Unix and Unix-like operating systems that defines how disk partitions, devices, or remote file systems should be automatically mounted during boot. It lists these file systems with their mount points, file system types, and relevant options. This allows for consistent and automated management of file system mounts.

This was also picked up by PEAS earlier
The MySQL enumeration revealed that zeno is the lastname of the edward user. There is a high likelihood that the password was reused. I will test it against the target SSH server.
